SYNOPSIS

9       sort [OPTION]... [FILE]...

DESCRIPTION

12       Write sorted concatenation of all FILE(s) to standard output.
13
14       Mandatory  arguments  to  long  options are mandatory for short options
15       too.  Ordering options:
16
17       -b, --ignore-leading-blanks
18              ignore leading blanks
19
20       -d, --dictionary-order
21              consider only blanks and alphanumeric characters
22
23       -f, --ignore-case
24              fold lower case to upper case characters
25
26       -g, --general-numeric-sort
27              compare according to general numerical value
28
29       -i, --ignore-nonprinting
30              consider only printable characters
31
32       -M, --month-sort
33              compare (unknown) < `JAN' < ... < `DEC'
34
35       -n, --numeric-sort
36              compare according to string numerical value
37
38       -R, --random-sort
39              sort by random hash of keys
40
41       --random-source=FILE
42              get random bytes from FILE (default /dev/urandom)
43
44       -r, --reverse
45              reverse the result of comparisons
46
47       Other options:
48
49       -c, --check, --check=diagnose-first
50              check for sorted input; do not sort
51
52       -C, --check=quiet, --check=silent
53              like -c, but do not report first bad line
54
55       --compress-program=PROG
56              compress temporaries with PROG; decompress them with PROG -d
57
58       -k, --key=POS1[,POS2]
59              start a key at POS1, end it at POS2 (origin 1)
60
61       -m, --merge
62              merge already sorted files; do not sort
63
64       -o, --output=FILE
65              write result to FILE instead of standard output
66
67       -s, --stable
68              stabilize sort by disabling last-resort comparison
69
70       -S, --buffer-size=SIZE
71              use SIZE for main memory buffer
72
73       -t, --field-separator=SEP
74              use SEP instead of non-blank to blank transition
75
76       -T, --temporary-directory=DIR
77              use DIR for temporaries, not $TMPDIR or /tmp;  multiple  options
78              specify multiple directories
79
80       -u, --unique
81              with  -c, check for strict ordering; without -c, output only the
82              first of an equal run
83
84       -z, --zero-terminated
85              end lines with 0 byte, not newline
86
87       --help display this help and exit
88
89       --version
90              output version information and exit
91
92       POS is F[.C][OPTS], where F is the field number  and  C  the  character
93       position  in  the field; both are origin 1.  If neither -t nor -b is in
94       effect, characters in a field are counted from  the  beginning  of  the
95       preceding  whitespace.   OPTS  is  one  or  more single-letter ordering
96       options, which override global ordering options for that  key.   If  no
97       key is given, use the entire line as the key.
98
99       SIZE  may be followed by the following multiplicative suffixes: % 1% of
100       memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.
101
102       With no FILE, or when FILE is -, read standard input.
103
104       *** WARNING *** The locale specified by the  environment  affects  sort
105       order.  Set LC_ALL=C to get the traditional sort order that uses native
106       byte values.
