sort - sort lines of text files
sort [OPTION]... [FILE]...
Write sorted concatenation of all FILE(s) to standard output.
Ordering options:
Mandatory arguments to long options are mandatory for short options too.
- -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, --reverse
- reverse the result of comparisons
Other options:
- -c, --check
- check whether input is sorted; do not sort
- -k, --key=POS1[,POS2]
- start a key at POS1, end it at POS 2 (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. 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.
