NAME

sort - sort lines of text files

SYNOPSIS

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

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'
-h, --human-numeric-sort: compare human readable numbers (e.g., 2K 1G)
-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
-r, --reverse: reverse the result of comparisons
--sort=WORD: sort according to WORD: general-numeric -g, human-numeric -h, month -M, numeric -n, random -R, version -V
-V, --version-sort: natural sort of (version) numbers within text

Other options:

--batch-size=NMERGE: 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-program=PROG: compress temporaries with PROG; decompress them with PROG -d
--debug: annotate the part of the line used to sort, and warn about questionable usage to stderr
--files0-from=F: read input from the files specified by NUL-terminated names in file F; If F is - then read names from standard input
-k, --key=KEYDEF: sort via a key; KEYDEF gives location and type
-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
--parallel=N: change the number of sorts run concurrently to N
-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

KEYDEF is F[.C][OPTS][,F[.C][OPTS]] for start and stop position, where F is a field number and C a character position in the field; both are origin 1, and the stop position defaults to the line's end. 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 [bdfgiMhnRrV], 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.
