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	tran-
	      sition

       -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.
