SYNOPSIS

9       test EXPRESSION
10       test
11
12       [ EXPRESSION ]
13       [ ]

DESCRIPTION

17       Exit with the status determined by EXPRESSION.
18
19       --help display this help and exit
20
21       --version
22              output version information and exit
23
24       An omitted EXPRESSION defaults to false.  Otherwise, EXPRESSION is true
25       or false and sets exit status.  It is one of:
26
27       ( EXPRESSION )
28              EXPRESSION is true
29
30       ! EXPRESSION
31              EXPRESSION is false
32
33       EXPRESSION1 -a EXPRESSION2
34              both EXPRESSION1 and EXPRESSION2 are true
35
36       EXPRESSION1 -o EXPRESSION2
37              either EXPRESSION1 or EXPRESSION2 is true
38
39       -n STRING
40              the length of STRING is nonzero
41
42       STRING equivalent to -n STRING
43
44       -z STRING
45              the length of STRING is zero
46
47       STRING1 = STRING2
48              the strings are equal
49
50       STRING1 != STRING2
51              the strings are not equal
52
53       INTEGER1 -eq INTEGER2
54              INTEGER1 is equal to INTEGER2
55
56       INTEGER1 -ge INTEGER2
57              INTEGER1 is greater than or equal to INTEGER2
58
59       INTEGER1 -gt INTEGER2
60              INTEGER1 is greater than INTEGER2
61
62       INTEGER1 -le INTEGER2
63              INTEGER1 is less than or equal to INTEGER2
64
65       INTEGER1 -lt INTEGER2
66              INTEGER1 is less than INTEGER2
67
68       INTEGER1 -ne INTEGER2
69              INTEGER1 is not equal to INTEGER2
70
71       FILE1 -ef FILE2
72              FILE1 and FILE2 have the same device and inode numbers
73
74       FILE1 -nt FILE2
75              FILE1 is newer (modification date) than FILE2
76
77       FILE1 -ot FILE2
78              FILE1 is older than FILE2
79
80       -b FILE
81              FILE exists and is block special
82
83       -c FILE
84              FILE exists and is character special
85
86       -d FILE
87              FILE exists and is a directory
88
89       -e FILE
90              FILE exists
91
92       -f FILE
93              FILE exists and is a regular file
94
95       -g FILE
96              FILE exists and is set-group-ID
97
98       -G FILE
99              FILE exists and is owned by the effective group ID
100
101       -h FILE
102              FILE exists and is a symbolic link (same as -L)
103
104       -k FILE
105              FILE exists and has its sticky bit set
106
107       -L FILE
108              FILE exists and is a symbolic link (same as -h)
109
110       -O FILE
111              FILE exists and is owned by the effective user ID
112
113       -p FILE
114              FILE exists and is a named pipe
115
116       -r FILE
117              FILE exists and read permission is granted
118
119       -s FILE
120              FILE exists and has a size greater than zero
121
122       -S FILE
123              FILE exists and is a socket
124
125       -t FD  file descriptor FD is opened on a terminal
126
127       -u FILE
128              FILE exists and its set-user-ID bit is set
129
130       -w FILE
131              FILE exists and write permission is granted
132
133       -x FILE
134              FILE exists and execute (or search) permission is granted
135
136       Except for -h and  -L,  all  FILE-related  tests  dereference  symbolic
137       links.   Beware  that  parentheses  need  to be escaped (e.g., by back‐
138       slashes) for shells.  INTEGER may also be -l STRING, which evaluates to
139       the length of STRING.
140
141       NOTE:  [  honors  the  --help and --version options, but test does not.
142       test treats each of those as it treats any other nonempty STRING.
143
144       NOTE: your shell may have its own version of test and/or [, which  usu‐
145       ally  supersedes  the  version  described  here.   Please refer to your
146       shell's documentation for details about the options it supports.
