47 builtin function instead of calling this utility directly.
50 In the first synopsis form,
52 will execute the provided command and apply checks specified
54 By default it will act as if it was run with
61 Multiple checks for the same output channel are allowed and, if specified,
62 their results will be combined as a logical and (meaning that the output must
63 match all the provided checks).
65 In the second synopsis form,
67 will print information about all supported options and their purpose.
69 The following options are available:
70 .Bl -tag -width XqualXvalueXX
71 .It Fl s Ar qual:value
72 Analyzes termination status.
74 .Bl -tag -width signal:<value> -compact
76 checks that the program exited cleanly and that its exit status is equal to
78 The exit code can be omitted altogether, in which case any clean exit is
81 ignores the exit check.
83 checks that the program exited due to a signal and that the signal that
86 The signal can be specified both as a number or as a name, or it can also
87 be omitted altogether, in which case any signal is accepted.
90 Most of these checkers can be prefixed by the
92 string, which effectively reverses the check.
93 .It Fl o Ar action:arg
94 Analyzes standard output.
96 .Bl -tag -width inline:<value> -compact
98 checks that stdout is empty
102 compares stdout with given file
103 .It Ar inline:<value>
104 compares stdout with inline value
105 .It Ar match:<regexp>
106 looks for a regular expression in stdout
108 saves stdout to given file
111 Most of these checkers can be prefixed by the
113 string, which effectively reverses the check.
114 .It Fl e Ar action:arg
115 Analyzes standard error (syntax identical to above)
119 as a shell command line, executing it with the system shell defined by
