WGET(1)                             GNU Wget                             WGET(1)



NAME
       Wget - The non-interactive network downloader.

SYNOPSIS
       wget [option]... [URL]...

DESCRIPTION
       GNU Wget is a free utility for non-interactive download of files from the
       Web.  It supports HTTP, HTTPS, and FTP protocols, as well as retrieval
       through HTTP proxies.

       Wget is non-interactive, meaning that it can work in the background,
       while the user is not logged on.  This allows you to start a retrieval
       and disconnect from the system, letting Wget finish the work.  By
       contrast, most of the Web browsers require constant user's presence,
       which can be a great hindrance when transferring a lot of data.

       Wget can follow links in HTML, XHTML, and CSS pages, to create local
       versions of remote web sites, fully recreating the directory structure of
       the original site.  This is sometimes referred to as "recursive
       downloading."  While doing that, Wget respects the Robot Exclusion
       Standard (/robots.txt).  Wget can be instructed to convert the links in
       downloaded files to point at the local files, for offline viewing.

       Wget has been designed for robustness over slow or unstable network
       connections; if a download fails due to a network problem, it will keep
       retrying until the whole file has been retrieved.  If the server supports
       regetting, it will instruct the server to continue the download from
       where it left off.

OPTIONS
   Option Syntax
       Since Wget uses GNU getopt to process command-line arguments, every
       option has a long form along with the short one.  Long options are more
       convenient to remember, but take time to type.  You may freely mix
       different option styles, or specify options after the command-line
       arguments.  Thus you may write:

               wget -r --tries=10 http://fly.srk.fer.hr/ -o log

       The space between the option accepting an argument and the argument may
       be omitted.  Instead of -o log you can write -olog.

       You may put several options that do not require arguments together, like:

               wget -drc <URL>

       This is completely equivalent to:

               wget -d -r -c <URL>

       Since the options can be specified after the arguments, you may terminate
       them with --.  So the following will try to download URL -x, reporting
       failure to log:

               wget -o log -- -x

       The options that accept comma-separated lists all respect the convention
       that specifying an empty list clears its value.  This can be useful to
       clear the .wgetrc settings.  For instance, if your .wgetrc sets
       "exclude_directories" to /cgi-bin, the following example will first reset
       it, and then set it to exclude /~nobody and /~somebody.  You can also
       clear the lists in .wgetrc.

               wget -X " -X /~nobody,/~somebody

       Most options that do not accept arguments are boolean options, so named
       because their state can be captured with a yes-or-no ("boolean")
       variable.  For example, --follow-ftp tells Wget to follow FTP links from
       HTML files and, on the other hand, --no-glob tells it not to perform file
       globbing on FTP URLs.  A boolean option is either affirmative or negative
       (beginning with --no).  All such options share several properties.

       Unless stated otherwise, it is assumed that the default behavior is the
       opposite of what the option accomplishes.  For example, the documented
       existence of --follow-ftp assumes that the default is to not follow FTP
       links from HTML pages.

       Affirmative options can be negated by prepending the --no- to the option
       name; negative options can be negated by omitting the --no- prefix.  This
       might seem superfluous---if the default for an affirmative option is to
       not do something, then why provide a way to explicitly turn it off?  But
       the startup file may in fact change the default.  For instance, using
       "follow_ftp = on" in .wgetrc makes Wget follow FTP links by default, and
       using --no-follow-ftp is the only way to restore the factory default from
       the command line.

   Basic Startup Options
       -V
       --version
           Display the version of Wget.

       -h
       --help
           Print a help message describing all of Wget's command-line options.

       -b
       --background
           Go to background immediately after startup.  If no output file is
           specified via the -o, output is redirected to wget-log.

       -e command
       --execute command
           Execute command as if it were a part of .wgetrc.  A command thus
           invoked will be executed after the commands in .wgetrc, thus taking
           precedence over them.  If you need to specify more than one wgetrc
           command, use multiple instances of -e.

   Logging and Input File Options
       -o logfile
       --output-file=logfile
           Log all messages to logfile.  The messages are normally reported to
           standard error.

       -a logfile
       --append-output=logfile
           Append to logfile.  This is the same as -o, only it appends to
           logfile instead of overwriting the old log file.  If logfile does not
           exist, a new file is created.

       -d
       --debug
           Turn on debug output, meaning various information important to the
           developers of Wget if it does not work properly.  Your system
           administrator may have chosen to compile Wget without debug support,
           in which case -d will not work.  Please note that compiling with
           debug support is always safe---Wget compiled with the debug support
           will not print any debug info unless requested with -d.

       -q
       --quiet
           Turn off Wget's output.

       -v
       --verbose
           Turn on verbose output, with all the available data.  The default
           output is verbose.

       -nv
       --no-verbose
           Turn off verbose without being completely quiet (use -q for that),
           which means that error messages and basic information still get
           printed.

       -i file
       --input-file=file
           Read URLs from a local or external file.  If - is specified as file,
           URLs are read from the standard input.  (Use ./- to read from a file
           literally named -.)

           If this function is used, no URLs need be present on the command
           line.  If there are URLs both on the command line and in an input
           file, those on the command lines will be the first ones to be
           retrieved.  If --force-html is not specified, then file should
           consist of a series of URLs, one per line.

           However, if you specify --force-html, the document will be regarded
           as html.  In that case you may have problems with relative links,
           which you can solve either by adding "<base href="url">" to the
           documents or by specifying --base=url on the command line.

           If the file is an external one, the document will be automatically
           treated as html if the Content-Type matches text/html.  Furthermore,
           the file's location will be implicitly used as base href if none was
           specified.

       -F
       --force-html
           When input is read from a file, force it to be treated as an HTML
           file.  This enables you to retrieve relative links from existing HTML
           files on your local disk, by adding "<base href="url">" to HTML, or
           using the --base command-line option.

       -B URL
       --base=URL
           Resolves relative links using URL as the point of reference, when
           reading links from an HTML file specified via the -i/--input-file
           option (together with --force-html, or when the input file was
           fetched remotely from a server describing it as HTML). This is
           equivalent to the presence of a "BASE" tag in the HTML input file,
           with URL as the value for the "href" attribute.

           For instance, if you specify http://foo/bar/a.html for URL, and Wget
           reads ../baz/b.html from the input file, it would be resolved to
           http://foo/baz/b.html.

       --config=FILE
           Specify the location of a startup file you wish to use.

   Download Options
       --bind-address=ADDRESS
           When making client TCP/IP connections, bind to ADDRESS on the local
           machine.  ADDRESS may be specified as a hostname or IP address.  This
           option can be useful if your machine is bound to multiple IPs.

       -t number
       --tries=number
           Set number of retries to number.  Specify 0 or inf for infinite
           retrying.  The default is to retry 20 times, with the exception of
           fatal errors like "connection refused" or "not found" (404), which
           are not retried.

       -O file
       --output-document=file
           The documents will not be written to the appropriate files, but all
           will be concatenated together and written to file.  If - is used as
           file, documents will be printed to standard output, disabling link
           conversion.  (Use ./- to print to a file literally named -.)

           Use of -O is not intended to mean simply "use the name file instead
           of the one in the URL;" rather, it is analogous to shell redirection:
           wget -O file http://foo is intended to work like wget -O - http://foo
           > file; file will be truncated immediately, and all downloaded
           content will be written there.

           For this reason, -N (for timestamp-checking) is not supported in
           combination with -O: since file is always newly created, it will
           always have a very new timestamp. A warning will be issued if this
           combination is used.

           Similarly, using -r or -p with -O may not work as you expect: Wget
           won't just download the first file to file and then download the rest
           to their normal names: all downloaded content will be placed in file.
           This was disabled in version 1.11, but has been reinstated (with a
           warning) in 1.11.2, as there are some cases where this behavior can
           actually have some use.

           Note that a combination with -k is only permitted when downloading a
           single document, as in that case it will just convert all relative
           URIs to external ones; -k makes no sense for multiple URIs when
           they're all being downloaded to a single file; -k can be used only
           when the output is a regular file.

       -nc
       --no-clobber
           If a file is downloaded more than once in the same directory, Wget's
           behavior depends on a few options, including -nc.  In certain cases,
           the local file will be clobbered, or overwritten, upon repeated
           download.  In other cases it will be preserved.

           When running Wget without -N, -nc, -r, or -p, downloading the same
           file in the same directory will result in the original copy of file
           being preserved and the second copy being named file.1.  If that file
           is downloaded yet again, the third copy will be named file.2, and so
           on.  (This is also the behavior with -nd, even if -r or -p are in
           effect.)  When -nc is specified, this behavior is suppressed, and
           Wget will refuse to download newer copies of file.  Therefore,
           ""no-clobber"" is actually a misnomer in this mode---it's not
           clobbering that's prevented (as the numeric suffixes were already
           preventing clobbering), but rather the multiple version saving that's
           prevented.

           When running Wget with -r or -p, but without -N, -nd, or -nc, re-
           downloading a file will result in the new copy simply overwriting the
           old.  Adding -nc will prevent this behavior, instead causing the
           original version to be preserved and any newer copies on the server
           to be ignored.

           When running Wget with -N, with or without -r or -p, the decision as
           to whether or not to download a newer copy of a file depends on the
           local and remote timestamp and size of the file.  -nc may not be
           specified at the same time as -N.

           Note that when -nc is specified, files with the suffixes .html or
           .htm will be loaded from the local disk and parsed as if they had
           been retrieved from the Web.

       -c
       --continue
           Continue getting a partially-downloaded file.  This is useful when
           you want to finish up a download started by a previous instance of
           Wget, or by another program.  For instance:

                   wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z

           If there is a file named ls-lR.Z in the current directory, Wget will
           assume that it is the first portion of the remote file, and will ask
           the server to continue the retrieval from an offset equal to the
           length of the local file.

           Note that you don't need to specify this option if you just want the
           current invocation of Wget to retry downloading a file should the
           connection be lost midway through.  This is the default behavior.  -c
           only affects resumption of downloads started prior to this invocation
           of Wget, and whose local files are still sitting around.

           Without -c, the previous example would just download the remote file
           to ls-lR.Z.1, leaving the truncated ls-lR.Z file alone.

           Beginning with Wget 1.7, if you use -c on a non-empty file, and it
           turns out that the server does not support continued downloading,
           Wget will refuse to start the download from scratch, which would
           effectively ruin existing contents.  If you really want the download
           to start from scratch, remove the file.

           Also beginning with Wget 1.7, if you use -c on a file which is of
           equal size as the one on the server, Wget will refuse to download the
           file and print an explanatory message.  The same happens when the
           file is smaller on the server than locally (presumably because it was
           changed on the server since your last download attempt)---because
           "continuing" is not meaningful, no download occurs.

           On the other side of the coin, while using -c, any file that's bigger
           on the server than locally will be considered an incomplete download
           and only "(length(remote) - length(local))" bytes will be downloaded
           and tacked onto the end of the local file.  This behavior can be
           desirable in certain cases---for instance, you can use wget -c to
           download just the new portion that's been appended to a data
           collection or log file.

           However, if the file is bigger on the server because it's been
           changed, as opposed to just appended to, you'll end up with a garbled
           file.  Wget has no way of verifying that the local file is really a
           valid prefix of the remote file.  You need to be especially careful
           of this when using -c in conjunction with -r, since every file will
           be considered as an "incomplete download" candidate.

           Another instance where you'll get a garbled file if you try to use -c
           is if you have a lame HTTP proxy that inserts a "transfer
           interrupted" string into the local file.  In the future a "rollback"
           option may be added to deal with this case.

           Note that -c only works with FTP servers and with HTTP servers that
           support the "Range" header.

       --progress=type
           Select the type of the progress indicator you wish to use.  Legal
           indicators are "dot" and "bar".

           The "bar" indicator is used by default.  It draws an ASCII progress
           bar graphics (a.k.a "thermometer" display) indicating the status of
           retrieval.  If the output is not a TTY, the "dot" bar will be used by
           default.

           Use --progress=dot to switch to the "dot" display.  It traces the
           retrieval by printing dots on the screen, each dot representing a
           fixed amount of downloaded data.

           When using the dotted retrieval, you may also set the style by
           specifying the type as dot:style.  Different styles assign different
           meaning to one dot.  With the "default" style each dot represents 1K,
           there are ten dots in a cluster and 50 dots in a line.  The "binary"
           style has a more "computer"-like orientation---8K dots, 16-dots
           clusters and 48 dots per line (which makes for 384K lines).  The
           "mega" style is suitable for downloading very large files---each dot
           represents 64K retrieved, there are eight dots in a cluster, and 48
           dots on each line (so each line contains 3M).

           Note that you can set the default style using the "progress" command
           in .wgetrc.  That setting may be overridden from the command line.
           The exception is that, when the output is not a TTY, the "dot"
           progress will be favored over "bar".  To force the bar output, use
           --progress=bar:force.

       -N
       --timestamping
           Turn on time-stamping.

       --no-use-server-timestamps
           Don't set the local file's timestamp by the one on the server.

           By default, when a file is downloaded, it's timestamps are set to
           match those from the remote file. This allows the use of
           --timestamping on subsequent invocations of wget. However, it is
           sometimes useful to base the local file's timestamp on when it was
           actually downloaded; for that purpose, the --no-use-server-timestamps
           option has been provided.

       -S
       --server-response
           Print the headers sent by HTTP servers and responses sent by FTP
           servers.

       --spider
           When invoked with this option, Wget will behave as a Web spider,
           which means that it will not download the pages, just check that they
           are there.  For example, you can use Wget to check your bookmarks:

                   wget --spider --force-html -i bookmarks.html

           This feature needs much more work for Wget to get close to the
           functionality of real web spiders.

       -T seconds
       --timeout=seconds
           Set the network timeout to seconds seconds.  This is equivalent to
           specifying --dns-timeout, --connect-timeout, and --read-timeout, all
           at the same time.

           When interacting with the network, Wget can check for timeout and
           abort the operation if it takes too long.  This prevents anomalies
           like hanging reads and infinite connects.  The only timeout enabled
           by default is a 900-second read timeout.  Setting a timeout to 0
           disables it altogether.  Unless you know what you are doing, it is
           best not to change the default timeout settings.
           All timeout-related options accept decimal values, as well as
           subsecond values.  For example, 0.1 seconds is a legal (though
           unwise) choice of timeout.  Subsecond timeouts are useful for
           checking server response times or for testing network latency.

       --dns-timeout=seconds
           Set the DNS lookup timeout to seconds seconds.  DNS lookups that
           don't complete within the specified time will fail.  By default,
           there is no timeout on DNS lookups, other than that implemented by
           system libraries.

       --connect-timeout=seconds
           Set the connect timeout to seconds seconds.  TCP connections that
           take longer to establish will be aborted.  By default, there is no
           connect timeout, other than that implemented by system libraries.

       --read-timeout=seconds
           Set the read (and write) timeout to seconds seconds.  The "time" of
           this timeout refers to idle time: if, at any point in the download,
           no data is received for more than the specified number of seconds,
           reading fails and the download is restarted.  This option does not
           directly affect the duration of the entire download.

           Of course, the remote server may choose to terminate the connection
           sooner than this option requires.  The default read timeout is 900
           seconds.

       --limit-rate=amount
           Limit the download speed to amount bytes per second.  Amount may be
           expressed in bytes, kilobytes with the k suffix, or megabytes with
           the m suffix.  For example, --limit-rate=20k will limit the retrieval
           rate to 20KB/s.  This is useful when, for whatever reason, you don't
           want Wget to consume the entire available bandwidth.

           This option allows the use of decimal numbers, usually in conjunction
           with power suffixes; for example, --limit-rate=2.5k is a legal value.

           Note that Wget implements the limiting by sleeping the appropriate
           amount of time after a network read that took less time than
           specified by the rate.  Eventually this strategy causes the TCP
           transfer to slow down to approximately the specified rate.  However,
           it may take some time for this balance to be achieved, so don't be
           surprised if limiting the rate doesn't work well with very small
           files.

       -w seconds
       --wait=seconds
           Wait the specified number of seconds between the retrievals.  Use of
           this option is recommended, as it lightens the server load by making
           the requests less frequent.  Instead of in seconds, the time can be
           specified in minutes using the "m" suffix, in hours using "h" suffix,
           or in days using "d" suffix.

           Specifying a large value for this option is useful if the network or
           the destination host is down, so that Wget can wait long enough to
           reasonably expect the network error to be fixed before the retry.
           The waiting interval specified by this function is influenced by
           "--random-wait", which see.

       --waitretry=seconds
           If you don't want Wget to wait between every retrieval, but only
           between retries of failed downloads, you can use this option.  Wget
           will use linear backoff, waiting 1 second after the first failure on
           a given file, then waiting 2 seconds after the second failure on that
           file, up to the maximum number of seconds you specify.

           By default, Wget will assume a value of 10 seconds.
       --random-wait
           Some web sites may perform log analysis to identify retrieval
           programs such as Wget by looking for statistically significant
           similarities in the time between requests. This option causes the
           time between requests to vary between 0.5 and 1.5 * wait seconds,
           where wait was specified using the --wait option, in order to mask
           Wget's presence from such analysis.

           A 2001 article in a publication devoted to development on a popular
           consumer platform provided code to perform this analysis on the fly.
           Its author suggested blocking at the class C address level to ensure
           automated retrieval programs were blocked despite changing DHCP-
           supplied addresses.

           The --random-wait option was inspired by this ill-advised
           recommendation to block many unrelated users from a web site due to
           the actions of one.

       --no-proxy
           Don't use proxies, even if the appropriate *_proxy environment
           variable is defined.

       -Q quota
       --quota=quota
           Specify download quota for automatic retrievals.  The value can be
           specified in bytes (default), kilobytes (with k suffix), or megabytes
           (with m suffix).

           Note that quota will never affect downloading a single file.  So if
           you specify wget -Q10k ftp://wuarchive.wustl.edu/ls-lR.gz, all of the
           ls-lR.gz will be downloaded.  The same goes even when several URLs
           are specified on the command-line.  However, quota is respected when
           retrieving either recursively, or from an input file.  Thus you may
           safely type wget -Q2m -i sites---download will be aborted when the
           quota is exceeded.

           Setting quota to 0 or to inf unlimits the download quota.

       --no-dns-cache
           Turn off caching of DNS lookups.  Normally, Wget remembers the IP
           addresses it looked up from DNS so it doesn't have to repeatedly
           contact the DNS server for the same (typically small) set of hosts it
           retrieves from.  This cache exists in memory only; a new Wget run
           will contact DNS again.

           However, it has been reported that in some situations it is not
           desirable to cache host names, even for the duration of a short-
           running application like Wget.  With this option Wget issues a new
           DNS lookup (more precisely, a new call to "gethostbyname" or
           "getaddrinfo") each time it makes a new connection.  Please note that
           this option will not affect caching that might be performed by the
           resolving library or by an external caching layer, such as NSCD.

           If you don't understand exactly what this option does, you probably
           won't need it.

       --restrict-file-names=modes
           Change which characters found in remote URLs must be escaped during
           generation of local filenames.  Characters that are restricted by
           this option are escaped, i.e. replaced with %HH, where HH is the
           hexadecimal number that corresponds to the restricted character. This
           option may also be used to force all alphabetical cases to be either
           lower- or uppercase.

           By default, Wget escapes the characters that are not valid or safe as
           part of file names on your operating system, as well as control
           characters that are typically unprintable.  This option is useful for
           changing these defaults, perhaps because you are downloading to a
           non-native partition, or because you want to disable escaping of the
           control characters, or you want to further restrict characters to
           only those in the ASCII range of values.

           The modes are a comma-separated set of text values. The acceptable
           values are unix, windows, nocontrol, ascii, lowercase, and uppercase.
           The values unix and windows are mutually exclusive (one will override
           the other), as are lowercase and uppercase. Those last are special
           cases, as they do not change the set of characters that would be
           escaped, but rather force local file paths to be converted either to
           lower- or uppercase.

           When "unix" is specified, Wget escapes the character / and the
           control characters in the ranges 0--31 and 128--159.  This is the
           default on Unix-like operating systems.

           When "windows" is given, Wget escapes the characters \, |, /, :, ?,
           ", *, <, >, and the control characters in the ranges 0--31 and
           128--159.  In addition to this, Wget in Windows mode uses + instead
           of : to separate host and port in local file names, and uses @
           instead of ? to separate the query portion of the file name from the
           rest.  Therefore, a URL that would be saved as
           www.xemacs.org:4300/search.pl?input=blah in Unix mode would be saved
           as www.xemacs.org+4300/search.pl@input=blah in Windows mode.  This
           mode is the default on Windows.

           If you specify nocontrol, then the escaping of the control characters
           is also switched off. This option may make sense when you are
           downloading URLs whose names contain UTF-8 characters, on a system
           which can save and display filenames in UTF-8 (some possible byte
           values used in UTF-8 byte sequences fall in the range of values
           designated by Wget as "controls").

           The ascii mode is used to specify that any bytes whose values are
           outside the range of ASCII characters (that is, greater than 127)
           shall be escaped. This can be useful when saving filenames whose
           encoding does not match the one used locally.

       -4
       --inet4-only
       -6
       --inet6-only
           Force connecting to IPv4 or IPv6 addresses.  With --inet4-only or -4,
           Wget will only connect to IPv4 hosts, ignoring AAAA records in DNS,
           and refusing to connect to IPv6 addresses specified in URLs.
           Conversely, with --inet6-only or -6, Wget will only connect to IPv6
           hosts and ignore A records and IPv4 addresses.

           Neither options should be needed normally.  By default, an IPv6-aware
           Wget will use the address family specified by the host's DNS record.
           If the DNS responds with both IPv4 and IPv6 addresses, Wget will try
           them in sequence until it finds one it can connect to.  (Also see
           "--prefer-family" option described below.)

           These options can be used to deliberately force the use of IPv4 or
           IPv6 address families on dual family systems, usually to aid
           debugging or to deal with broken network configuration.  Only one of
           --inet6-only and --inet4-only may be specified at the same time.
           Neither option is available in Wget compiled without IPv6 support.

       --prefer-family=none/IPv4/IPv6
           When given a choice of several addresses, connect to the addresses
           with specified address family first.  The address order returned by
           DNS is used without change by default.

           This avoids spurious errors and connect attempts when accessing hosts
           that resolve to both IPv6 and IPv4 addresses from IPv4 networks.  For
           example, www.kame.net resolves to 2001:200:0:8002:203:47ff:fea5:3085
           and to 203.178.141.194.  When the preferred family is "IPv4", the
           IPv4 address is used first; when the preferred family is "IPv6", the
           IPv6 address is used first; if the specified value is "none", the
           address order returned by DNS is used without change.

           Unlike -4 and -6, this option doesn't inhibit access to any address
           family, it only changes the order in which the addresses are
           accessed.  Also note that the reordering performed by this option is
           stable---it doesn't affect order of addresses of the same family.
           That is, the relative order of all IPv4 addresses and of all IPv6
           addresses remains intact in all cases.

       --retry-connrefused
           Consider "connection refused" a transient error and try again.
           Normally Wget gives up on a URL when it is unable to connect to the
           site because failure to connect is taken as a sign that the server is
           not running at all and that retries would not help.  This option is
           for mirroring unreliable sites whose servers tend to disappear for
           short periods of time.

       --user=user
       --password=password
           Specify the username user and password password for both FTP and HTTP
           file retrieval.  These parameters can be overridden using the
           --ftp-user and --ftp-password options for FTP connections and the
           --http-user and --http-password options for HTTP connections.

       --ask-password
           Prompt for a password for each connection established. Cannot be
           specified when --password is being used, because they are mutually
           exclusive.

       --no-iri
           Turn off internationalized URI (IRI) support. Use --iri to turn it
           on. IRI support is activated by default.

           You can set the default state of IRI support using the "iri" command
           in .wgetrc. That setting may be overridden from the command line.

       --local-encoding=encoding
           Force Wget to use encoding as the default system encoding. That
           affects how Wget converts URLs specified as arguments from locale to
           UTF-8 for IRI support.

           Wget use the function "nl_langinfo()" and then the "CHARSET"
           environment variable to get the locale. If it fails, ASCII is used.

           You can set the default local encoding using the "local_encoding"
           command in .wgetrc. That setting may be overridden from the command
           line.

       --remote-encoding=encoding
           Force Wget to use encoding as the default remote server encoding.
           That affects how Wget converts URIs found in files from remote
           encoding to UTF-8 during a recursive fetch. This options is only
           useful for IRI support, for the interpretation of non-ASCII
           characters.

           For HTTP, remote encoding can be found in HTTP "Content-Type" header
           and in HTML "Content-Type http-equiv" meta tag.

           You can set the default encoding using the "remoteencoding" command
           in .wgetrc. That setting may be overridden from the command line.

       --unlink
           Force Wget to unlink file instead of clobbering existing file. This
           option is useful for downloading to the directory with hardlinks.
   Directory Options
       -nd
       --no-directories
           Do not create a hierarchy of directories when retrieving recursively.
           With this option turned on, all files will get saved to the current
           directory, without clobbering (if a name shows up more than once, the
           filenames will get extensions .n).

       -x
       --force-directories
           The opposite of -nd---create a hierarchy of directories, even if one
           would not have been created otherwise.  E.g. wget -x
           http://fly.srk.fer.hr/robots.txt will save the downloaded file to
           fly.srk.fer.hr/robots.txt.

       -nH
       --no-host-directories
           Disable generation of host-prefixed directories.  By default,
           invoking Wget with -r http://fly.srk.fer.hr/ will create a structure
           of directories beginning with fly.srk.fer.hr/.  This option disables
           such behavior.

       --protocol-directories
           Use the protocol name as a directory component of local file names.
           For example, with this option, wget -r http://host will save to
           http/host/... rather than just to host/....

       --cut-dirs=number
           Ignore number directory components.  This is useful for getting a
           fine-grained control over the directory where recursive retrieval
           will be saved.

           Take, for example, the directory at ftp://ftp.xemacs.org/pub/xemacs/.
           If you retrieve it with -r, it will be saved locally under
           ftp.xemacs.org/pub/xemacs/.  While the -nH option can remove the
           ftp.xemacs.org/ part, you are still stuck with pub/xemacs.  This is
           where --cut-dirs comes in handy; it makes Wget not "see" number
           remote directory components.  Here are several examples of how
           --cut-dirs option works.

                   No options        -> ftp.xemacs.org/pub/xemacs/
                   -nH               -> pub/xemacs/
                   -nH --cut-dirs=1  -> xemacs/
                   -nH --cut-dirs=2  -> .

                   --cut-dirs=1      -> ftp.xemacs.org/xemacs/
                   ...

           If you just want to get rid of the directory structure, this option
           is similar to a combination of -nd and -P.  However, unlike -nd,
           --cut-dirs does not lose with subdirectories---for instance, with -nH
           --cut-dirs=1, a beta/ subdirectory will be placed to xemacs/beta, as
           one would expect.

       -P prefix
       --directory-prefix=prefix
           Set directory prefix to prefix.  The directory prefix is the
           directory where all other files and subdirectories will be saved to,
           i.e. the top of the retrieval tree.  The default is . (the current
           directory).

   HTTP Options
       --default-page=name
           Use name as the default file name when it isn't known (i.e., for URLs
           that end in a slash), instead of index.html.

       -E
       --adjust-extension
           If a file of type application/xhtml+xml or text/html is downloaded
           and the URL does not end with the regexp \.[Hh][Tt][Mm][Ll]?, this
           option will cause the suffix .html to be appended to the local
           filename.  This is useful, for instance, when you're mirroring a
           remote site that uses .asp pages, but you want the mirrored pages to
           be viewable on your stock Apache server.  Another good use for this
           is when you're downloading CGI-generated materials.  A URL like
           http://site.com/article.cgi?25 will be saved as article.cgi?25.html.

           Note that filenames changed in this way will be re-downloaded every
           time you re-mirror a site, because Wget can't tell that the local
           X.html file corresponds to remote URL X (since it doesn't yet know
           that the URL produces output of type text/html or
           application/xhtml+xml.

           As of version 1.12, Wget will also ensure that any downloaded files
           of type text/css end in the suffix .css, and the option was renamed
           from --html-extension, to better reflect its new behavior. The old
           option name is still acceptable, but should now be considered
           deprecated.

           At some point in the future, this option may well be expanded to
           include suffixes for other types of content, including content types
           that are not parsed by Wget.

       --http-user=user
       --http-password=password
           Specify the username user and password password on an HTTP server.
           According to the type of the challenge, Wget will encode them using
           either the "basic" (insecure), the "digest", or the Windows "NTLM"
           authentication scheme.

           Another way to specify username and password is in the URL itself.
           Either method reveals your password to anyone who bothers to run
           "ps".  To prevent the passwords from being seen, store them in
           .wgetrc or .netrc, and make sure to protect those files from other
           users with "chmod".  If the passwords are really important, do not
           leave them lying in those files either---edit the files and delete
           them after Wget has started the download.

       --no-http-keep-alive
           Turn off the "keep-alive" feature for HTTP downloads.  Normally, Wget
           asks the server to keep the connection open so that, when you
           download more than one document from the same server, they get
           transferred over the same TCP connection.  This saves time and at the
           same time reduces the load on the server.

           This option is useful when, for some reason, persistent (keep-alive)
           connections don't work for you, for example due to a server bug or
           due to the inability of server-side scripts to cope with the
           connections.

       --no-cache
           Disable server-side cache.  In this case, Wget will send the remote
           server an appropriate directive (Pragma: no-cache) to get the file
           from the remote service, rather than returning the cached version.
           This is especially useful for retrieving and flushing out-of-date
           documents on proxy servers.

           Caching is allowed by default.

       --no-cookies
           Disable the use of cookies.  Cookies are a mechanism for maintaining
           server-side state.  The server sends the client a cookie using the
           "Set-Cookie" header, and the client responds with the same cookie
           upon further requests.  Since cookies allow the server owners to keep
           track of visitors and for sites to exchange this information, some
           consider them a breach of privacy.  The default is to use cookies;
           however, storing cookies is not on by default.

       --load-cookies file
           Load cookies from file before the first HTTP retrieval.  file is a
           textual file in the format originally used by Netscape's cookies.txt
           file.

           You will typically use this option when mirroring sites that require
           that you be logged in to access some or all of their content.  The
           login process typically works by the web server issuing an HTTP
           cookie upon receiving and verifying your credentials.  The cookie is
           then resent by the browser when accessing that part of the site, and
           so proves your identity.

           Mirroring such a site requires Wget to send the same cookies your
           browser sends when communicating with the site.  This is achieved by
           --load-cookies---simply point Wget to the location of the cookies.txt
           file, and it will send the same cookies your browser would send in
           the same situation.  Different browsers keep textual cookie files in
           different locations:

           Netscape 4.x.
               The cookies are in ~/.netscape/cookies.txt.

           Mozilla and Netscape 6.x.
               Mozilla's cookie file is also named cookies.txt, located
               somewhere under ~/.mozilla, in the directory of your profile.
               The full path usually ends up looking somewhat like
               ~/.mozilla/default/some-weird-string/cookies.txt.

           Internet Explorer.
               You can produce a cookie file Wget can use by using the File
               menu, Import and Export, Export Cookies.  This has been tested
               with Internet Explorer 5; it is not guaranteed to work with
               earlier versions.

           Other browsers.
               If you are using a different browser to create your cookies,
               --load-cookies will only work if you can locate or produce a
               cookie file in the Netscape format that Wget expects.

           If you cannot use --load-cookies, there might still be an
           alternative.  If your browser supports a "cookie manager", you can
           use it to view the cookies used when accessing the site you're
           mirroring.  Write down the name and value of the cookie, and manually
           instruct Wget to send those cookies, bypassing the "official" cookie
           support:

                   wget --no-cookies --header "Cookie: <name>=<value>"

       --save-cookies file
           Save cookies to file before exiting.  This will not save cookies that
           have expired or that have no expiry time (so-called "session
           cookies"), but also see --keep-session-cookies.

       --keep-session-cookies
           When specified, causes --save-cookies to also save session cookies.
           Session cookies are normally not saved because they are meant to be
           kept in memory and forgotten when you exit the browser.  Saving them
           is useful on sites that require you to log in or to visit the home
           page before you can access some pages.  With this option, multiple
           Wget runs are considered a single browser session as far as the site
           is concerned.

           Since the cookie file format does not normally carry session cookies,
           Wget marks them with an expiry timestamp of 0.  Wget's --load-cookies
           recognizes those as session cookies, but it might confuse other
           browsers.  Also note that cookies so loaded will be treated as other
           session cookies, which means that if you want --save-cookies to
           preserve them again, you must use --keep-session-cookies again.

       --ignore-length
           Unfortunately, some HTTP servers (CGI programs, to be more precise)
           send out bogus "Content-Length" headers, which makes Wget go wild, as
           it thinks not all the document was retrieved.  You can spot this
           syndrome if Wget retries getting the same document again and again,
           each time claiming that the (otherwise normal) connection has closed
           on the very same byte.

           With this option, Wget will ignore the "Content-Length" header---as
           if it never existed.

       --header=header-line
           Send header-line along with the rest of the headers in each HTTP
           request.  The supplied header is sent as-is, which means it must
           contain name and value separated by colon, and must not contain
           newlines.

           You may define more than one additional header by specifying --header
           more than once.

                   wget --header='Accept-Charset: iso-8859-2' \
                        --header='Accept-Language: hr'        \
                          http://fly.srk.fer.hr/

           Specification of an empty string as the header value will clear all
           previous user-defined headers.

           As of Wget 1.10, this option can be used to override headers
           otherwise generated automatically.  This example instructs Wget to
           connect to localhost, but to specify foo.bar in the "Host" header:

                   wget --header="Host: foo.bar" http://localhost/

           In versions of Wget prior to 1.10 such use of --header caused sending
           of duplicate headers.

       --max-redirect=number
           Specifies the maximum number of redirections to follow for a
           resource.  The default is 20, which is usually far more than
           necessary. However, on those occasions where you want to allow more
           (or fewer), this is the option to use.

       --proxy-user=user
       --proxy-password=password
           Specify the username user and password password for authentication on
           a proxy server.  Wget will encode them using the "basic"
           authentication scheme.

           Security considerations similar to those with --http-password pertain
           here as well.

       --referer=url
           Include `Referer: url' header in HTTP request.  Useful for retrieving
           documents with server-side processing that assume they are always
           being retrieved by interactive web browsers and only come out
           properly when Referer is set to one of the pages that point to them.

       --save-headers
           Save the headers sent by the HTTP server to the file, preceding the
           actual contents, with an empty line as the separator.

       -U agent-string
       --user-agent=agent-string
           Identify as agent-string to the HTTP server.

           The HTTP protocol allows the clients to identify themselves using a
           "User-Agent" header field.  This enables distinguishing the WWW
           software, usually for statistical purposes or for tracing of protocol
           violations.  Wget normally identifies as Wget/version, version being
           the current version number of Wget.

           However, some sites have been known to impose the policy of tailoring
           the output according to the "User-Agent"-supplied information.  While
           this is not such a bad idea in theory, it has been abused by servers
           denying information to clients other than (historically) Netscape or,
           more frequently, Microsoft Internet Explorer.  This option allows you
           to change the "User-Agent" line issued by Wget.  Use of this option
           is discouraged, unless you really know what you are doing.

           Specifying empty user agent with --user-agent="" instructs Wget not
           to send the "User-Agent" header in HTTP requests.

       --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified
           data in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work
           in exactly the same way. In particular, they both expect content of
           the form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file.
           In particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

           Please be aware that Wget needs to know the size of the POST data in
           advance.  Therefore the argument to "--post-file" must be a regular
           file; specifying a FIFO or something like /dev/stdin won't work.
           It's not quite clear how to work around this limitation inherent in
           HTTP/1.0.  Although HTTP/1.1 introduces chunked transfer that doesn't
           require knowing the request length in advance, a client can't use
           chunked unless it knows it's talking to an HTTP/1.1 server.  And it
           can't know that until it receives a response, which in turn requires
           the request to have been completed -- a chicken-and-egg problem.

           Note: if Wget is redirected after the POST request is completed, it
           will not send the POST data to the redirected URL.  This is because
           URLs that process POST often respond with a redirection to a regular
           page, which does not desire or accept POST.  It is not completely
           clear that this behavior is optimal; if it doesn't work out, it might
           be changed in the future.

           This example shows how to log to a server using POST and then proceed
           to download the desired pages, presumably only accessible to
           authorized users:

                   # Log in to the server.  This can be done only once.
                   wget --save-cookies cookies.txt \
                        --post-data 'user=foo&password=bar' \
                        http://server.com/auth.php

                   # Now grab the page or pages we care about.
                   wget --load-cookies cookies.txt \
                        -p http://server.com/interesting/article.php

           If the server is using session cookies to track user authentication,
           the above will not work because --save-cookies will not save them
           (and neither will browsers) and the cookies.txt file will be empty.
           In that case use --keep-session-cookies along with --save-cookies to
           force saving of session cookies.

       --content-disposition
           If this is set to on, experimental (not fully-functional) support for
           "Content-Disposition" headers is enabled. This can currently result
           in extra round-trips to the server for a "HEAD" request, and is known
           to suffer from a few bugs, which is why it is not currently enabled
           by default.

           This option is useful for some file-downloading CGI programs that use
           "Content-Disposition" headers to describe what the name of a
           downloaded file should be.

       --trust-server-names
           If this is set to on, on a redirect the last component of the
           redirection URL will be used as the local file name.  By default it
           is used the last component in the original URL.

       --auth-no-challenge
           If this option is given, Wget will send Basic HTTP authentication
           information (plaintext username and password) for all requests, just
           like Wget 1.10.2 and prior did by default.

           Use of this option is not recommended, and is intended only to
           support some few obscure servers, which never send HTTP
           authentication challenges, but accept unsolicited auth info, say, in
           addition to form-based authentication.

   HTTPS (SSL/TLS) Options
       To support encrypted HTTP (HTTPS) downloads, Wget must be compiled with
       an external SSL library, currently OpenSSL.  If Wget is compiled without
       SSL support, none of these options are available.

       --secure-protocol=protocol
           Choose the secure protocol to be used.  Legal values are auto, SSLv2,
           SSLv3, and TLSv1.  If auto is used, the SSL library is given the
           liberty of choosing the appropriate protocol automatically, which is
           achieved by sending an SSLv2 greeting and announcing support for
           SSLv3 and TLSv1.  This is the default.

           Specifying SSLv2, SSLv3, or TLSv1 forces the use of the corresponding
           protocol.  This is useful when talking to old and buggy SSL server
           implementations that make it hard for OpenSSL to choose the correct
           protocol version.  Fortunately, such servers are quite rare.

       --no-check-certificate
           Don't check the server certificate against the available certificate
           authorities.  Also don't require the URL host name to match the
           common name presented by the certificate.

           As of Wget 1.10, the default is to verify the server's certificate
           against the recognized certificate authorities, breaking the SSL
           handshake and aborting the download if the verification fails.
           Although this provides more secure downloads, it does break
           interoperability with some sites that worked with previous Wget
           versions, particularly those using self-signed, expired, or otherwise
           invalid certificates.  This option forces an "insecure" mode of
           operation that turns the certificate verification errors into
           warnings and allows you to proceed.

           If you encounter "certificate verification" errors or ones saying
           that "common name doesn't match requested host name", you can use
           this option to bypass the verification and proceed with the download.
           Only use this option if you are otherwise convinced of the site's
           authenticity, or if you really don't care about the validity of its
           certificate.  It is almost always a bad idea not to check the
           certificates when transmitting confidential or important data.

       --certificate=file
           Use the client certificate stored in file.  This is needed for
           servers that are configured to require certificates from the clients
           that connect to them.  Normally a certificate is not required and
           this switch is optional.

       --certificate-type=type
           Specify the type of the client certificate.  Legal values are PEM
           (assumed by default) and DER, also known as ASN1.

       --private-key=file
           Read the private key from file.  This allows you to provide the
           private key in a file separate from the certificate.

       --private-key-type=type
           Specify the type of the private key.  Accepted values are PEM (the
           default) and DER.

       --ca-certificate=file
           Use file as the file with the bundle of certificate authorities
           ("CA") to verify the peers.  The certificates must be in PEM format.

           Without this option Wget looks for CA certificates at the system-
           specified locations, chosen at OpenSSL installation time.

       --ca-directory=directory
           Specifies directory containing CA certificates in PEM format.  Each
           file contains one CA certificate, and the file name is based on a
           hash value derived from the certificate.  This is achieved by
           processing a certificate directory with the "c_rehash" utility
           supplied with OpenSSL.  Using --ca-directory is more efficient than
           --ca-certificate when many certificates are installed because it
           allows Wget to fetch certificates on demand.

           Without this option Wget looks for CA certificates at the system-
           specified locations, chosen at OpenSSL installation time.

       --random-file=file
           Use file as the source of random data for seeding the pseudo-random
           number generator on systems without /dev/random.

           On such systems the SSL library needs an external source of
           randomness to initialize.  Randomness may be provided by EGD (see
           --egd-file below) or read from an external source specified by the
           user.  If this option is not specified, Wget looks for random data in
           $RANDFILE or, if that is unset, in $HOME/.rnd.  If none of those are
           available, it is likely that SSL encryption will not be usable.

           If you're getting the "Could not seed OpenSSL PRNG; disabling SSL."
           error, you should provide random data using some of the methods
           described above.

       --egd-file=file
           Use file as the EGD socket.  EGD stands for Entropy Gathering Daemon,
           a user-space program that collects data from various unpredictable
           system sources and makes it available to other programs that might
           need it.  Encryption software, such as the SSL library, needs sources
           of non-repeating randomness to seed the random number generator used
           to produce cryptographically strong keys.

           OpenSSL allows the user to specify his own source of entropy using
           the "RAND_FILE" environment variable.  If this variable is unset, or
           if the specified file does not produce enough randomness, OpenSSL
           will read random data from EGD socket specified using this option.

           If this option is not specified (and the equivalent startup command
           is not used), EGD is never contacted.  EGD is not needed on modern
           Unix systems that support /dev/random.

   FTP Options
       --ftp-user=user
       --ftp-password=password
           Specify the username user and password password on an FTP server.
           Without this, or the corresponding startup option, the password
           defaults to -wget@, normally used for anonymous FTP.

           Another way to specify username and password is in the URL itself.
           Either method reveals your password to anyone who bothers to run
           "ps".  To prevent the passwords from being seen, store them in
           .wgetrc or .netrc, and make sure to protect those files from other
           users with "chmod".  If the passwords are really important, do not
           leave them lying in those files either---edit the files and delete
           them after Wget has started the download.

       --no-remove-listing
           Don't remove the temporary .listing files generated by FTP
           retrievals.  Normally, these files contain the raw directory listings
           received from FTP servers.  Not removing them can be useful for
           debugging purposes, or when you want to be able to easily check on
           the contents of remote server directories (e.g. to verify that a
           mirror you're running is complete).

           Note that even though Wget writes to a known filename for this file,
           this is not a security hole in the scenario of a user making .listing
           a symbolic link to /etc/passwd or something and asking "root" to run
           Wget in his or her directory.  Depending on the options used, either
           Wget will refuse to write to .listing, making the
           globbing/recursion/time-stamping operation fail, or the symbolic link
           will be deleted and replaced with the actual .listing file, or the
           listing will be written to a .listing.number file.

           Even though this situation isn't a problem, though, "root" should
           never run Wget in a non-trusted user's directory.  A user could do
           something as simple as linking index.html to /etc/passwd and asking
           "root" to run Wget with -N or -r so the file will be overwritten.

       --no-glob
           Turn off FTP globbing.  Globbing refers to the use of shell-like
           special characters (wildcards), like *, ?, [ and ] to retrieve more
           than one file from the same directory at once, like:

                   wget ftp://gnjilux.srk.fer.hr/*.msg

           By default, globbing will be turned on if the URL contains a globbing
           character.  This option may be used to turn globbing on or off
           permanently.

           You may have to quote the URL to protect it from being expanded by
           your shell.  Globbing makes Wget look for a directory listing, which
           is system-specific.  This is why it currently works only with Unix
           FTP servers (and the ones emulating Unix "ls" output).

       --no-passive-ftp
           Disable the use of the passive FTP transfer mode.  Passive FTP
           mandates that the client connect to the server to establish the data
           connection rather than the other way around.

           If the machine is connected to the Internet directly, both passive
           and active FTP should work equally well.  Behind most firewall and
           NAT configurations passive FTP has a better chance of working.
           However, in some rare firewall configurations, active FTP actually
           works when passive FTP doesn't.  If you suspect this to be the case,
           use this option, or set "passive_ftp=off" in your init file.

       --retr-symlinks
           By default, when retrieving FTP directories recursively and a
           symbolic link is encountered, the symbolic link is traversed and the
           pointed-to files are retrieved.  Currently, Wget does not traverse
           symbolic links to directories to download them recursively, though
           this feature may be added in the future.

           When --retr-symlinks=no is specified, the linked-to file is not
           downloaded.  Instead, a matching symbolic link is created on the
           local filesystem.  The pointed-to file will not be retrieved unless
           this recursive retrieval would have encountered it separately and
           downloaded it anyway.  This option poses a security risk where a
           malicious FTP Server may cause Wget to write to files outside of the
           intended directories through a specially crafted .LISTING file.

           Note that when retrieving a file (not a directory) because it was
           specified on the command-line, rather than because it was recursed
           to, this option has no effect.  Symbolic links are always traversed
           in this case.

   Recursive Retrieval Options
       -r
       --recursive
           Turn on recursive retrieving.    The default maximum depth is 5.

       -l depth
       --level=depth
           Specify recursion maximum depth level depth.

       --delete-after
           This option tells Wget to delete every single file it downloads,
           after having done so.  It is useful for pre-fetching popular pages
           through a proxy, e.g.:

                   wget -r -nd --delete-after http://whatever.com/~popular/page/

           The -r option is to retrieve recursively, and -nd to not create
           directories.

           Note that --delete-after deletes files on the local machine.  It does
           not issue the DELE command to remote FTP sites, for instance.  Also
           note that when --delete-after is specified, --convert-links is
           ignored, so .orig files are simply not created in the first place.

       -k
       --convert-links
           After the download is complete, convert the links in the document to
           make them suitable for local viewing.  This affects not only the
           visible hyperlinks, but any part of the document that links to
           external content, such as embedded images, links to style sheets,
           hyperlinks to non-HTML content, etc.

           Each link will be changed in one of the two ways:

           ·   The links to files that have been downloaded by Wget will be
               changed to refer to the file they point to as a relative link.

               Example: if the downloaded file /foo/doc.html links to
               /bar/img.gif, also downloaded, then the link in doc.html will be
               modified to point to ../bar/img.gif.  This kind of transformation
               works reliably for arbitrary combinations of directories.

           ·   The links to files that have not been downloaded by Wget will be
               changed to include host name and absolute path of the location
               they point to.

               Example: if the downloaded file /foo/doc.html links to
               /bar/img.gif (or to ../bar/img.gif), then the link in doc.html
               will be modified to point to http://hostname/bar/img.gif.

           Because of this, local browsing works reliably: if a linked file was
           downloaded, the link will refer to its local name; if it was not
           downloaded, the link will refer to its full Internet address rather
           than presenting a broken link.  The fact that the former links are
           converted to relative links ensures that you can move the downloaded
           hierarchy to another directory.

           Note that only at the end of the download can Wget know which links
           have been downloaded.  Because of that, the work done by -k will be
           performed at the end of all the downloads.

       -K
       --backup-converted
           When converting a file, back up the original version with a .orig
           suffix.  Affects the behavior of -N.

       -m
       --mirror
           Turn on options suitable for mirroring.  This option turns on
           recursion and time-stamping, sets infinite recursion depth and keeps
           FTP directory listings.  It is currently equivalent to -r -N -l inf
           --no-remove-listing.

       -p
       --page-requisites
           This option causes Wget to download all the files that are necessary
           to properly display a given HTML page.  This includes such things as
           inlined images, sounds, and referenced stylesheets.

           Ordinarily, when downloading a single HTML page, any requisite
           documents that may be needed to display it properly are not
           downloaded.  Using -r together with -l can help, but since Wget does
           not ordinarily distinguish between external and inlined documents,
           one is generally left with "leaf documents" that are missing their
           requisites.
           For instance, say document 1.html contains an "<IMG>" tag referencing
           1.gif and an "<A>" tag pointing to external document 2.html.  Say
           that 2.html is similar but that its image is 2.gif and it links to
           3.html.  Say this continues up to some arbitrarily high number.

           If one executes the command:

                   wget -r -l 2 http://<site>/1.html

           then 1.html, 1.gif, 2.html, 2.gif, and 3.html will be downloaded.  As
           you can see, 3.html is without its requisite 3.gif because Wget is
           simply counting the number of hops (up to 2) away from 1.html in
           order to determine where to stop the recursion.  However, with this
           command:

                   wget -r -l 2 -p http://<site>/1.html

           all the above files and 3.html's requisite 3.gif will be downloaded.
           Similarly,

                   wget -r -l 1 -p http://<site>/1.html

           will cause 1.html, 1.gif, 2.html, and 2.gif to be downloaded.  One
           might think that:

                   wget -r -l 0 -p http://<site>/1.html

           would download just 1.html and 1.gif, but unfortunately this is not
           the case, because -l 0 is equivalent to -l inf---that is, infinite
           recursion.  To download a single HTML page (or a handful of them, all
           specified on the command-line or in a -i URL input file) and its (or
           their) requisites, simply leave off -r and -l:

                   wget -p http://<site>/1.html

           Note that Wget will behave as if -r had been specified, but only that
           single page and its requisites will be downloaded.  Links from that
           page to external documents will not be followed.  Actually, to
           download a single page and all its requisites (even if they exist on
           separate websites), and make sure the lot displays properly locally,
           this author likes to use a few options in addition to -p:

                   wget -E -H -k -K -p http://<site>/<document>

           To finish off this topic, it's worth knowing that Wget's idea of an
           external document link is any URL specified in an "<A>" tag, an
           "<AREA>" tag, or a "<LINK>" tag other than "<LINK REL="stylesheet">".

       --strict-comments
           Turn on strict parsing of HTML comments.  The default is to terminate
           comments at the first occurrence of -->.

           According to specifications, HTML comments are expressed as SGML
           declarations.  Declaration is special markup that begins with <! and
           ends with >, such as <!DOCTYPE ...>, that may contain comments
           between a pair of -- delimiters.  HTML comments are "empty
           declarations", SGML declarations without any non-comment text.
           Therefore, <!--foo--> is a valid comment, and so is <!--one--
           --two-->, but <!--1--2--> is not.

           On the other hand, most HTML writers don't perceive comments as
           anything other than text delimited with <!-- and -->, which is not
           quite the same.  For example, something like <!------------> works as
           a valid comment as long as the number of dashes is a multiple of four
           (!).  If not, the comment technically lasts until the next --, which
           may be at the other end of the document.  Because of this, many
           popular browsers completely ignore the specification and implement
           what users have come to expect: comments delimited with <!-- and -->.

           Until version 1.9, Wget interpreted comments strictly, which resulted
           in missing links in many web pages that displayed fine in browsers,
           but had the misfortune of containing non-compliant comments.
           Beginning with version 1.9, Wget has joined the ranks of clients that
           implements "naive" comments, terminating each comment at the first
           occurrence of -->.

           If, for whatever reason, you want strict comment parsing, use this
           option to turn it on.

   Recursive Accept/Reject Options
       -A acclist --accept acclist
       -R rejlist --reject rejlist
           Specify comma-separated lists of file name suffixes or patterns to
           accept or reject. Note that if any of the wildcard characters, *, ?,
           [ or ], appear in an element of acclist or rejlist, it will be
           treated as a pattern, rather than a suffix.

       -D domain-list
       --domains=domain-list
           Set domains to be followed.  domain-list is a comma-separated list of
           domains.  Note that it does not turn on -H.

       --exclude-domains domain-list
           Specify the domains that are not to be followed.

       --follow-ftp
           Follow FTP links from HTML documents.  Without this option, Wget will
           ignore all the FTP links.

       --follow-tags=list
           Wget has an internal table of HTML tag / attribute pairs that it
           considers when looking for linked documents during a recursive
           retrieval.  If a user wants only a subset of those tags to be
           considered, however, he or she should be specify such tags in a
           comma-separated list with this option.

       --ignore-tags=list
           This is the opposite of the --follow-tags option.  To skip certain
           HTML tags when recursively looking for documents to download, specify
           them in a comma-separated list.

           In the past, this option was the best bet for downloading a single
           page and its requisites, using a command-line like:

                   wget --ignore-tags=a,area -H -k -K -r http://<site>/<document>

           However, the author of this option came across a page with tags like
           "<LINK REL="home" HREF="/">" and came to the realization that
           specifying tags to ignore was not enough.  One can't just tell Wget
           to ignore "<LINK>", because then stylesheets will not be downloaded.
           Now the best bet for downloading a single page and its requisites is
           the dedicated --page-requisites option.

       --ignore-case
           Ignore case when matching files and directories.  This influences the
           behavior of -R, -A, -I, and -X options, as well as globbing
           implemented when downloading from FTP sites.  For example, with this
           option, -A *.txt will match file1.txt, but also file2.TXT, file3.TxT,
           and so on.

       -H
       --span-hosts
           Enable spanning across hosts when doing recursive retrieving.

       -L
       --relative
           Follow relative links only.  Useful for retrieving a specific home
           page without any distractions, not even those from the same hosts.

       -I list
       --include-directories=list
           Specify a comma-separated list of directories you wish to follow when
           downloading.  Elements of list may contain wildcards.

       -X list
       --exclude-directories=list
           Specify a comma-separated list of directories you wish to exclude
           from download.  Elements of list may contain wildcards.

       -np
       --no-parent
           Do not ever ascend to the parent directory when retrieving
           recursively.  This is a useful option, since it guarantees that only
           the files below a certain hierarchy will be downloaded.

FILES
       /etc/wgetrc
           Default location of the global startup file.

       .wgetrc
           User startup file.

BUGS
       You are welcome to submit bug reports via the GNU Wget bug tracker (see
       <http://wget.addictivecode.org/BugTracker>).

       Before actually submitting a bug report, please try to follow a few
       simple guidelines.

       1.  Please try to ascertain that the behavior you see really is a bug.
           If Wget crashes, it's a bug.  If Wget does not behave as documented,
           it's a bug.  If things work strange, but you are not sure about the
           way they are supposed to work, it might well be a bug, but you might
           want to double-check the documentation and the mailing lists.

       2.  Try to repeat the bug in as simple circumstances as possible.  E.g.
           if Wget crashes while downloading wget -rl0 -kKE -t5 --no-proxy
           http://yoyodyne.com -o /tmp/log, you should try to see if the crash
           is repeatable, and if will occur with a simpler set of options.  You
           might even try to start the download at the page where the crash
           occurred to see if that page somehow triggered the crash.

           Also, while I will probably be interested to know the contents of
           your .wgetrc file, just dumping it into the debug message is probably
           a bad idea.  Instead, you should first try to see if the bug repeats
           with .wgetrc moved out of the way.  Only if it turns out that .wgetrc
           settings affect the bug, mail me the relevant parts of the file.

       3.  Please start Wget with -d option and send us the resulting output (or
           relevant parts thereof).  If Wget was compiled without debug support,
           recompile it---it is much easier to trace bugs with debug support on.

           Note: please make sure to remove any potentially sensitive
           information from the debug log before sending it to the bug address.
           The "-d" won't go out of its way to collect sensitive information,
           but the log will contain a fairly complete transcript of Wget's
           communication with the server, which may include passwords and pieces
           of downloaded data.  Since the bug address is publically archived,
           you may assume that all bug reports are visible to the public.

       4.  If Wget has crashed, try to run it in a debugger, e.g. "gdb `which
           wget` core" and type "where" to get the backtrace.  This may not work
           if the system administrator has disabled core files, but it is safe
           to try.

       This is not the complete manual for GNU Wget.  For more complete
       information, including more detailed explanations of some of the options,

       option, see the GNU Info entry for wget.
