Name
sort — sort lines of text files
Synopsis
sort [OPTION...] [FILE...]
DESCRIPTION
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
−−random−source=FILE-
get random bytes from FILE (default
/dev/urandom)
−r, −−reverse-
reverse the result of comparisons
Other options:
−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−program=PROG-
compress temporaries with PROG; decompress them with
PROG −d
−k, −−key=POS1[,POS2]-
start a key at POS1, end it at POS2 (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
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
−−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 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.
