.SH DESCRIPTION

.PP
Write sorted concatenation of all FILE(s) to standard output.
.PP
Mandatory arguments to long options are mandatory for short options too.
Ordering options:
.TP
\fB\-b\fR, \fB\-\-ignore\-leading\-blanks\fR
ignore leading blanks
.TP
\fB\-d\fR, \fB\-\-dictionary\-order\fR
consider only blanks and alphanumeric characters
.TP
\fB\-f\fR, \fB\-\-ignore\-case\fR
fold lower case to upper case characters
.TP
\fB\-g\fR, \fB\-\-general\-numeric\-sort\fR
compare according to general numerical value
.TP
\fB\-i\fR, \fB\-\-ignore\-nonprinting\fR
consider only printable characters
.TP
\fB\-M\fR, \fB\-\-month\-sort\fR
compare (unknown) < `JAN' < ... < `DEC'
.TP
\fB\-n\fR, \fB\-\-numeric\-sort\fR
compare according to string numerical value
.TP
\fB\-R\fR, \fB\-\-random\-sort\fR
sort by random hash of keys
.TP
\fB\-\-random\-source\fR=\fIFILE\fR
get random bytes from FILE (default /dev/urandom)
.TP
\fB\-r\fR, \fB\-\-reverse\fR
reverse the result of comparisons
.PP
Other options:
.TP
\fB\-c\fR, \fB\-\-check\fR
check whether input is sorted; do not sort
.TP
\fB\-k\fR, \fB\-\-key\fR=\fIPOS1[\fR,POS2]
start a key at POS1, end it at POS2 (origin 1)
.TP
\fB\-m\fR, \fB\-\-merge\fR
merge already sorted files; do not sort
.TP
\fB\-o\fR, \fB\-\-output\fR=\fIFILE\fR
write result to FILE instead of standard output
.TP
\fB\-s\fR, \fB\-\-stable\fR
stabilize sort by disabling last\-resort comparison
.TP
\fB\-S\fR, \fB\-\-buffer\-size\fR=\fISIZE\fR
use SIZE for main memory buffer
.TP
\fB\-t\fR, \fB\-\-field\-separator\fR=\fISEP\fR
use SEP instead of non\-blank to blank transition
.TP
\fB\-T\fR, \fB\-\-temporary\-directory\fR=\fIDIR\fR
use DIR for temporaries, not $TMPDIR or /tmp;
multiple options specify multiple directories
.TP
\fB\-u\fR, \fB\-\-unique\fR
with \fB\-c\fR, check for strict ordering;
without \fB\-c\fR, output only the first of an equal run
.TP
\fB\-z\fR, \fB\-\-zero\-terminated\fR
end lines with 0 byte, not newline
.TP
\fB\-\-help\fR
display this help and exit
.TP
\fB\-\-version\fR
output version information and exit
.PP
POS is F[.C][OPTS], where F is the field number and C the character position
in the field; both are origin 1.  If neither \fB\-t\fR nor \fB\-b\fR is in effect, characters
in a field are counted from the beginning of the preceding whitespace.  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.
.PP
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.
.PP
With no FILE, or when FILE is \-, read standard input.
.PP
*** 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.
