6 sort - sort lines of text files
7
9 sort [OPTION]... [FILE]...
10 sort [OPTION]... --files0-from=F
11
13 Write sorted concatenation of all FILE(s) to standard output.
14
15 With no FILE, or when FILE is -, read standard input.
16
17 Mandatory arguments to long options are mandatory for short options
18 too. Ordering options:
19
20 -b, --ignore-leading-blanks
21 ignore leading blanks
22
23 -d, --dictionary-order
24 consider only blanks and alphanumeric characters
25
26 -f, --ignore-case
27 fold lower case to upper case characters
28
29 -g, --general-numeric-sort
30 compare according to general numerical value
31
32 -i, --ignore-nonprinting
33 consider only printable characters
34
35 -M, --month-sort
36 compare (unknown) < 'JAN' < ... < 'DEC'
37
38 -h, --human-numeric-sort
39 compare human readable numbers (e.g., 2K 1G)
40
41 -n, --numeric-sort
42 compare according to string numerical value
43
44 -R, --random-sort
45 shuffle, but group identical keys. See shuf(1)
46
47 --random-source=FILE
48 get random bytes from FILE
49
50 -r, --reverse
51 reverse the result of comparisons
52
53 --sort=WORD
54 sort according to WORD: general-numeric -g, human-numeric -h,
55 month -M, numeric -n, random -R, version -V
56
57 -V, --version-sort
58 natural sort of (version) numbers within text
59
60 Other options:
61
62 --batch-size=NMERGE
63 merge at most NMERGE inputs at once; for more use temp files
64
65 -c, --check, --check=diagnose-first
66 check for sorted input; do not sort
67
68 -C, --check=quiet, --check=silent
69 like -c, but do not report first bad line
70
71 --compress-program=PROG
72 compress temporaries with PROG; decompress them with PROG -d
73
74 --debug
75 annotate the part of the line used to sort, and warn about ques‐
76 tionable usage to stderr
77
78 --files0-from=F
79 read input from the files specified by NUL-terminated names in
80 file F; If F is - then read names from standard input
81
82 -k, --key=KEYDEF
83 sort via a key; KEYDEF gives location and type
84
85 -m, --merge
86 merge already sorted files; do not sort
87
88 -o, --output=FILE
89 write result to FILE instead of standard output
90
91 -s, --stable
92 stabilize sort by disabling last-resort comparison
93
94 -S, --buffer-size=SIZE
95 use SIZE for main memory buffer
96
97 -t, --field-separator=SEP
98 use SEP instead of non-blank to blank transition
99
100 -T, --temporary-directory=DIR
101 use DIR for temporaries, not $TMPDIR or /tmp; multiple options
102 specify multiple directories
103
104 --parallel=N
105 change the number of sorts run concurrently to N
106
107 -u, --unique
108 with -c, check for strict ordering; without -c, output only the
109 first of an equal run
110
111 -z, --zero-terminated
112 line delimiter is NUL, not newline
113
114 --help display this help and exit
115
116 --version
117 output version information and exit
118
119 KEYDEF is F[.C][OPTS][,F[.C][OPTS]] for start and stop position, where
120 F is a field number and C a character position in the field; both are
121 origin 1, and the stop position defaults to the line's end. If neither
122 -t nor -b is in effect, characters in a field are counted from the be‐
123 ginning of the preceding whitespace. OPTS is one or more single-letter
124 ordering options [bdfgiMhnRrV], which override global ordering options
125 for that key. If no key is given, use the entire line as the key. Use
126 --debug to diagnose incorrect key usage.
127
128 SIZE may be followed by the following multiplicative suffixes: % 1% of
129 memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y, R, Q.
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.
