SORT(1)                                 User Commands                                SORT(1)

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.

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

       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
              shuffle, but group identical keys.  See shuf(1)

       --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,  nu‐
              meric -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 questionable 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=KEYDEF
              sort via a key; KEYDEF gives location and type

       -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 multi‐
              ple 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
              line delimiter is NUL, not newline

       --help display this help and exit

       --version
              output version information and exit

       KEYDEF  is  F[.C][OPTS][,F[.C][OPTS]] for start and stop position, where F is a field
       number and C a character position in the field; both are origin 1, and the stop posi‐
       tion  defaults to the line's end.  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 [bdfgiMhnRrV], which override global ordering op‐
       tions for that key.  If no key is given, use the entire line as the key.  Use --debug
       to diagnose incorrect key usage.

       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.

       *** 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.
