23 | $BUILTIN test | - |
24 | $FUNCTION test_builtin | - |
25 | $SHORT_DOC test [expr] | - |
26 | Evaluate conditional expression. | - |
27 | | - |
28 | Exits with a status of 0 (true) or 1 (false) depending on | - |
29 | the evaluation of EXPR. Expressions may be unary or binary. Unary | - |
30 | expressions are often used to examine the status of a file. There | - |
31 | are string operators and numeric comparison operators as well. | - |
32 | | - |
33 | The behavior of test depends on the number of arguments. Read the | - |
34 | bash manual page for the complete specification. | - |
35 | | - |
36 | File operators: | - |
37 | | - |
38 | -a FILE True if file exists. | - |
39 | -b FILE True if file is block special. | - |
40 | -c FILE True if file is character special. | - |
41 | -d FILE True if file is a directory. | - |
42 | -e FILE True if file exists. | - |
43 | -f FILE True if file exists and is a regular file. | - |
44 | -g FILE True if file is set-group-id. | - |
45 | -h FILE True if file is a symbolic link. | - |
46 | -L FILE True if file is a symbolic link. | - |
47 | -k FILE True if file has its `sticky' bit set. | - |
48 | -p FILE True if file is a named pipe. | - |
49 | -r FILE True if file is readable by you. | - |
50 | -s FILE True if file exists and is not empty. | - |
51 | -S FILE True if file is a socket. | - |
52 | -t FD True if FD is opened on a terminal. | - |
53 | -u FILE True if the file is set-user-id. | - |
54 | -w FILE True if the file is writable by you. | - |
55 | -x FILE True if the file is executable by you. | - |
56 | -O FILE True if the file is effectively owned by you. | - |
57 | -G FILE True if the file is effectively owned by your group. | - |
58 | -N FILE True if the file has been modified since it was last read. | - |
59 | | - |
60 | FILE1 -nt FILE2 True if file1 is newer than file2 (according to | - |
61 | modification date). | - |
62 | | - |
63 | FILE1 -ot FILE2 True if file1 is older than file2. | - |
64 | | - |
65 | FILE1 -ef FILE2 True if file1 is a hard link to file2. | - |
66 | | - |
67 | String operators: | - |
68 | | - |
69 | -z STRING True if string is empty. | - |
70 | | - |
71 | -n STRING | - |
72 | STRING True if string is not empty. | - |
73 | | - |
74 | STRING1 = STRING2 | - |
75 | True if the strings are equal. | - |
76 | STRING1 != STRING2 | - |
77 | True if the strings are not equal. | - |
78 | STRING1 < STRING2 | - |
79 | True if STRING1 sorts before STRING2 lexicographically. | - |
80 | STRING1 > STRING2 | - |
81 | True if STRING1 sorts after STRING2 lexicographically. | - |
82 | | - |
83 | Other operators: | - |
84 | | - |
85 | -o OPTION True if the shell option OPTION is enabled. | - |
86 | -v VAR True if the shell variable VAR is set. | - |
87 | -R VAR True if the shell variable VAR is set and is a name | - |
88 | reference. | - |
89 | ! EXPR True if expr is false. | - |
90 | EXPR1 -a EXPR2 True if both expr1 AND expr2 are true. | - |
91 | EXPR1 -o EXPR2 True if either expr1 OR expr2 is true. | - |
92 | | - |
93 | arg1 OP arg2 Arithmetic tests. OP is one of -eq, -ne, | - |
94 | -lt, -le, -gt, or -ge. | - |
95 | | - |
96 | Arithmetic binary operators return true if ARG1 is equal, not-equal, | - |
97 | less-than, less-than-or-equal, greater-than, or greater-than-or-equal | - |
98 | than ARG2. | - |
99 | | - |
100 | Exit Status: | - |
101 | Returns success if EXPR evaluates to true; fails if EXPR evaluates to | - |
102 | false or an invalid argument is given. | - |
