NAME
sort - sort lines of text files
SYNOPSIS
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 compari-
son
-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.
