SYNOPSIS

9       sort [OPTION]... [FILE]...
10       sort [OPTION]... --files0-from=F
11

DESCRIPTION

13       Write sorted concatenation of all FILE(s) to standard output.
14
15       Mandatory  arguments  to  long  options are mandatory for short options
16       too.  Ordering options:
17
18       -b, --ignore-leading-blanks
19              ignore leading blanks
20
21       -d, --dictionary-order
22              consider only blanks and alphanumeric characters
23
24       -f, --ignore-case
25              fold lower case to upper case characters
26
27       -g, --general-numeric-sort
28              compare according to general numerical value
29
30       -i, --ignore-nonprinting
31              consider only printable characters
32
33       -M, --month-sort
34              compare (unknown) < `JAN' < ... < `DEC'
35
36       -h, --human-numeric-sort
37              compare human readable numbers (e.g., 2K 1G)
38
39       -n, --numeric-sort
40              compare according to string numerical value
41
42       -R, --random-sort
43              sort by random hash of keys
44
45       --random-source=FILE
46              get random bytes from FILE
47
48       -r, --reverse
49              reverse the result of comparisons
50
51       --sort=WORD
52              sort according to WORD: general-numeric  -g,  human-numeric  -h,
53              month -M, numeric -n, random -R, version -V
54
55       -V, --version-sort
56              natural sort of (version) numbers within text
57
58       Other options:
59
60       --batch-size=NMERGE
61              merge at most NMERGE inputs at once; for more use temp files
62
63       -c, --check, --check=diagnose-first
64              check for sorted input; do not sort
65
66       -C, --check=quiet, --check=silent
67              like -c, but do not report first bad line
68
69       --compress-program=PROG
70              compress temporaries with PROG; decompress them with PROG -d
71
72       --files0-from=F
73              read  input  from the files specified by NUL-terminated names in
74              file F; If F is - then read names from standard input
75
76       -k, --key=POS1[,POS2]
77              start a key at POS1 (origin 1), end it at POS2 (default  end  of
78              line)
79
80       -m, --merge
81              merge already sorted files; do not sort
82
83       -o, --output=FILE
84              write result to FILE instead of standard output
85
86       -s, --stable
87              stabilize sort by disabling last-resort comparison
88
89       -S, --buffer-size=SIZE
90              use SIZE for main memory buffer
91
92       -t, --field-separator=SEP
93              use SEP instead of non-blank to blank transition
94
95       -T, --temporary-directory=DIR
96              use  DIR  for temporaries, not $TMPDIR or /tmp; multiple options
97              specify multiple directories
98
99       -u, --unique
100              with -c, check for strict ordering; without -c, output only  the
101              first of an equal run
102
103       -z, --zero-terminated
104              end lines with 0 byte, not newline
105
106       --help display this help and exit
107
108       --version
109              output version information and exit
110
111       POS  is  F[.C][OPTS],  where  F is the field number and C the character
112       position in the field; both are origin 1.  If neither -t nor -b  is  in
113       effect,  characters  in  a  field are counted from the beginning of the
114       preceding whitespace.  OPTS  is  one  or  more  single-letter  ordering
115       options,  which  override  global ordering options for that key.  If no
116       key is given, use the entire line as the key.
117
118       SIZE may be followed by the following multiplicative suffixes: % 1%  of
119       memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.
120
121       With no FILE, or when FILE is -, read standard input.
122
123       ***  WARNING  ***  The locale specified by the environment affects sort
124       order.  Set LC_ALL=C to get the traditional sort order that uses native
125       byte values.
