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       --debug
73              annotate the part of the line used to sort, and warn about ques‐
74              tionable usage to stderr
75
76       --files0-from=F
77              read input from the files specified by NUL-terminated  names  in
78              file F; If F is - then read names from standard input
79
80       -k, --key=KEYDEF
81              sort via a key; KEYDEF gives location and type
82
83       -m, --merge
84              merge already sorted files; do not sort
85
86       -o, --output=FILE
87              write result to FILE instead of standard output
88
89       -s, --stable
90              stabilize sort by disabling last-resort comparison
91
92       -S, --buffer-size=SIZE
93              use SIZE for main memory buffer
94
95       -t, --field-separator=SEP
96              use SEP instead of non-blank to blank transition
97
98       -T, --temporary-directory=DIR
99              use  DIR  for temporaries, not $TMPDIR or /tmp; multiple options
100              specify multiple directories
101
102       --parallel=N
103              change the number of sorts run concurrently to N
104
105       -u, --unique
106              with -c, check for strict ordering; without -c, output only  the
107              first of an equal run
108
109       -z, --zero-terminated
110              end lines with 0 byte, not newline
111
112       --help display this help and exit
113
114       --version
115              output version information and exit
116
117       KEYDEF  is F[.C][OPTS][,F[.C][OPTS]] for start and stop position, where
118       F is a field number and C a character position in the field;  both  are
119       origin 1, and the stop position defaults to the line's end.  If neither
120       -t nor -b is in effect, characters in a  field  are  counted  from  the
121       beginning of the preceding whitespace.  OPTS is one or more single-let‐
122       ter ordering options  [bdfgiMhnRrV],  which  override  global  ordering
123       options  for  that key.  If no key is given, use the entire line as the
124       key.
125
126       SIZE may be followed by the following multiplicative suffixes: % 1%  of
127       memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.
128
129       With no FILE, or when FILE is -, read standard input.
130
131       ***  WARNING  ***  The locale specified by the environment affects sort
132       order.  Set LC_ALL=C to get the traditional sort order that uses native
133       byte values.
