NAME
sort - sort lines of text files
SYNOPSIS
sort [\,OPTION\/]... [\,FILE\/]...
sort [\,OPTION\/]... \,--files0-from=F\/
sort [\,OPTION\/]... \,--files0-from=F\/
DESCRIPTION
Write sorted concatenation of all FILE(s) to standard output.
With no FILE, or when FILE is -, read standard input.
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 | |
shuffle, but group identical keys. See shuf(1) | |
--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 | |
line delimiter is NUL, not newline | |
--help | display this help and exit |
--version | |
output version information and exit |
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.
*** 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.
