atf-check -- executes a command and analyzes its results
atf-check [-s qual:value] [-o action:arg ...] [-e action:arg ...] [-x] command atf-check -h
atf-check executes a given command and analyzes its results, including exit code, stdout and stderr. In the first synopsis form, atf-check will execute the provided command and apply checks specified by arguments. By default it will act as if it was run with -s exit:0 -o empty -e empty. Multiple checks for the same output channel are allowed and, if specified, their results will be com- bined as a logical and (meaning that the output must match all the pro- vided checks). In the second synopsis form, atf-check will print information about all supported options and their purpose. The following options are available: -h Shows a short summary of all available options and their purpose. -s qual:value Analyzes termination status. Must be one of: exit:<value> checks that the program exited cleanly and that its exit status is equal to value. The exit code can be omitted altogether, in which case any clean exit is accepted. ignore ignores the exit check. signal:<value> checks that the program exited due to a signal and that the signal that terminated it is value. The signal can be specified both as a number or as a name, or it can also be omitted altogether, in which case any signal is accepted. Most of these checkers can be prefixed by the `not-' string, which effectively reverses the check. -o action:arg Analyzes standard output. Must be one of: empty checks that stdout is empty ignore ignores stdout file:<path> compares stdout with given file inline:<value> compares stdout with inline value match:<regexp> looks for a regular expression in stdout save:<path> saves stdout to given file Most of these checkers can be prefixed by the `not-' string, which effectively reverses the check. -e action:arg Analyzes standard error (syntax identical to above) -x Executes command as a shell command line, executing it with the system shell defined by ATF_SHELL in atf-config(1). You should avoid using this flag if at all possible to prevent shell quoting issues.
atf-check exits 0 on success, and other (unspecified) value on failure.
