NAME
sort - sort lines of text filesSYNOPSIS
sort [OPTION]... [FILE]...DESCRIPTION
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- to whitespace 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
otherwise: 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.
