sort — sort lines of text files
sort [OPTION...] [FILE...]
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−blanksignore leading blanks
−d, −−dictionary−orderconsider only blanks and alphanumeric characters
−f, −−ignore−casefold lower case to upper case characters
−g, −−general−numeric−sortcompare according to general numerical value
−i, −−ignore−nonprintingconsider only printable characters
−M, −−month−sortcompare (unknown) < `JAN' < ... < `DEC'
−n, −−numeric−sortcompare according to string numerical value
−R, −−random−sortsort by random hash of keys
−−random−source=FILEget random bytes from FILE (default /dev/urandom)
−−sort=WORDsort according to WORD: general−numeric
−g, month
−M, numeric
−n, random
−R
−r, −−reversereverse the result of comparisons
Other options:
−c, −−check, −−check=diagnose−firstcheck for sorted input; do not sort
−C, −−check=quiet, −−check=silentlike −c, but do
not report first bad line
−−compress−program=PROGcompress temporaries with PROG; decompress them with
PROG −d
−k, −−key=POS1[,POS2]start a key at POS1, end it at POS2 (origin 1)
−m, −−mergemerge already sorted files; do not sort
−o, −−output=FILEwrite result to FILE instead of standard output
−s, −−stablestabilize sort by disabling last−resort comparison
−S, −−buffer−size=SIZEuse SIZE for main memory buffer
−t, −−field−separator=SEPuse SEP instead of non−blank to blank transition
−T, −−temporary−directory=DIRuse DIR for temporaries, not $TMPDIR or /tmp; multiple options specify multiple directories
−u, −−uniquewith −c, check for
strict ordering; without −c, output only the first of an
equal run
−z, −−zero−terminatedend lines with 0 byte, not newline
−−helpdisplay this help and exit
−−versionoutput 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.
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 coreutils 'sort invocation'
should give you access to the complete manual.
