NAME
       sort - sort lines of text files

SYNOPSIS
       sort [OPTION]... [FILE]...
       sort [OPTION]... --files0-from=F

DESCRIPTION
       Write sorted concatenation of all FILE(s) to standard output.

       Mandatory  arguments to long options are mandatory for short options too.
       Ordering options:

       -b, --ignore-leading-blanks
              ignore leading blanks

       -d, --dictionary-order
              consider only blanks and alphanumeric characters

       -f, --ignore-case
              fold lower case to upper case characters

       -g, --general-numeric-sort
              compare according to general numerical value

       -i, --ignore-nonprinting
              consider only printable characters

       -M, --month-sort
              compare (unknown) < `JAN' < ... < `DEC'

       -h, --human-numeric-sort
              compare human readable numbers (e.g., 2K 1G)

       -n, --numeric-sort
              compare according to string numerical value

       -R, --random-sort
              sort by random hash of keys

       --random-source=FILE
              get random bytes from FILE

       -r, --reverse
              reverse the result of comparisons

       --sort=WORD
              sort according to  WORD:  general-numeric  -g,  human-numeric  -h,
              month -M, numeric -n, random -R, version -V

       -V, --version-sort
              natural sort of (version) numbers within text

       Other options:

       --batch-size=NMERGE
              merge at most NMERGE inputs at once; for more use temp files

       -c, --check, --check=diagnose-first
              check for sorted input; do not sort

       -C, --check=quiet, --check=silent
              like -c, but do not report first bad line
       --compress-program=PROG
              compress temporaries with PROG; decompress them with PROG -d

       --debug
              annotate  the  part of the line used to sort, and warn about ques‐
              tionable usage to stderr

       --files0-from=F
              read input from the files specified  by  NUL-terminated  names  in
              file F; If F is - then read names from standard input

       -k, --key=POS1[,POS2]
              start  a  key  at  POS1 (origin 1), end it at POS2 (default end of
              line).  See POS syntax below

       -m, --merge
              merge already sorted files; do not sort

       -o, --output=FILE
              write result to FILE instead of standard output

       -s, --stable
              stabilize sort by disabling last-resort comparison

       -S, --buffer-size=SIZE
              use SIZE for main memory buffer

       -t, --field-separator=SEP
              use SEP instead of non-blank to blank transition

       -T, --temporary-directory=DIR
              use DIR for temporaries, not $TMPDIR  or  /tmp;  multiple  options
              specify multiple directories

       --parallel=N
              change the number of sorts run concurrently to N

       -u, --unique
              with  -c,  check  for strict ordering; without -c, output only the
              first of an equal run

       -z, --zero-terminated
              end lines with 0 byte, not newline

       --help display this help and exit

       --version
              output version information and exit

       POS is F[.C][OPTS], where F is the field number and C the character posi‐
       tion in the field; both are origin 1.  If neither -t nor -b is in effect,
       characters in a field are counted from the  beginning  of  the  preceding
       whitespace.   OPTS  is  one or more single-letter ordering options, which
       override global ordering options for that key.  If no key is  given,  use
       the entire line as the key.

       SIZE  may  be  followed by the following multiplicative suffixes: % 1% of
       memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.

       With no FILE, or when FILE is -, read standard input.

       *** WARNING *** The locale specified  by  the  environment  affects  sort
       order.   Set  LC_ALL=C to get the traditional sort order that uses native
       byte values.
