Sort

NAME

      sort(1,3) - sort(1,3) lines of text files

SYNOPSIS

      sort(1,3) [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(3,n) numerical value

      -r, --reverse
             reverse the result of comparisons

      Other options:

      -c, --check
             check whether input is sorted; do not sort(1,3)

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

      -m, --merge
             merge(1,8) already sorted files; do not sort(1,3)

      -o, --output=FILE
             write(1,2) result to FILE instead of standard output

      -s, --stable
             stabilize sort(1,3) 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 transi-
             tion

      -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(3,n,1 builtins)

      --version
             output version(1,3,5) information and exit(3,n,1 builtins)

      POS  is  F[.C][OPTS],  where  F is the field number and C the character
      position in(1,8) 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(2,n,1 builtins) standard input.

      ***  WARNING  ***  The locale(3,5,7) specified by the environment affects sort(1,3)
      order.  Set LC_ALL=C to get the traditional sort(1,3) order that uses native
      byte values.
