sort - sort lines of text files
sort [OPTION]... [FILE]...
Write sorted concatenation of all FILE(s) to standard output.
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 [\040-\0176] characters in keys
start a key at POS1, end it *at* POS2 field numbers and character
offsets are numbered starting with one (contrast with zerobased
-m merge already sorted files, do not sort
-M compare (unknown) < `JAN' < ... < `DEC', imply -b
-n compare according to string numerical value, imply -b
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
use DIRECTORY for temporary files, not $TMPDIR or /tmp
-u with -c: check for strict ordering otherwise: output only the
first of an equal run
-z end lines with 0 byte, not newline, for find -print0
--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 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.
