SORT(1)				 User Commands			       SORT(1)

       sort - sort lines of text files

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

       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'

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

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

	      get random bytes from FILE (default /dev/urandom)

       -r, --reverse
	      reverse the result of comparisons

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

       -V, --version-sort
	      sort by numeric version

       Other options:

	      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 temporaries with	PROG; decompress them with PROG	-d

	      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

       -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

	      output version information and exit

       POS  is	F[.C][OPTS],  where  F is the field number and C the character
       position	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.
