sort - sort lines of text files
sort [OPTION]... [FILE]...
Write sorted concatenation of all FILE(s) to standard output.
- +POS1 [-POS2]
- start a key at POS1, end it *before* POS2 (obsolescent)
- field numbers and
character offsets are numbered
- starting with zero (contrast with the -k
option)
- -b
- ignore leading blanks in sort fields or keys
- -c
- check if given
files already sorted, do not sort
- -d
- consider only [a-zA-Z0-9 ] characters
in keys
- -f
- fold lower case to upper case characters in keys
- -g
- compare according
to general numerical value, imply -b
- -i
- consider only [ 40- 176] characters
in keys
- -k POS1[,POS2]
- start a key at POS1, end it *at* POS2
- field numbers
and character offsets are numbered
- starting with one (contrast with zero-based
+POS form)
- -m
- merge already sorted files, do not sort
- -M
- compare (unknown)
< `JAN' < ... < `DEC', imply -b
- -n
- compare according to string numerical value, imply
-b
- -o FILE
- write result on FILE instead of standard output
- -r
- reverse the
result of comparisons
- -s
- stabilize sort by disabling last resort comparison
- -t SEP
- use SEParator instead of non- to whitespace transition
- -T DIRECTORY
- use DIRECTORY for temporary files, not $TMPDIR or /tmp
- -u
- with -c, check
for strict ordering; with -m, only output the first of an equal sequence
- -z
- end lines with 0 byte, not newline, for find -print0
- --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,
both counted from one with -k, from zero with the obsolescent form. OPTS
is made up of one or more of Mbdfinr; this effectively disables global
-Mbdfinr settings for that key. If no key is given, use the entire line
as the key. With no FILE, or when FILE is -, read standard input.

The full documentation for
sort is maintained as a Texinfo manual. If the info and sort programs are
properly installed at your site, the command
- info sort
should give you
access to the complete manual.
