SORT(1)                          User Commands                         SORT(1)

NAME
       sort - sort lines of text files

SYNOPSIS
       sort [OPTION]... [FILE]...

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

       Ordering options:

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

       -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'

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

       -r, --reverse
              reverse the result of comparisons

       Other options:

       -c, --check
              check whether input is sorted; do not sort

       -k, --key=POS1[,POS2]
              start a key at POS1, end it at POS 2 (origin 1)

       -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

       -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
       position in the field.  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.
