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 out-
put.
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, ver-
sion -V

User Commands SORT(1)
-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 stan-
dard 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

User Commands SORT(1)
-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 posi-
tion, 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 sin-
gle-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 suf-
fixes: % 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.
