38 	Specify module name in which perf-probe searches probe points
39 	or lines. If a path of module file is passed, perf-probe
40 	treat it as an offline module (this means you can add a probe on
59 	Define a probe event (see PROBE SYNTAX for detail).
63 	Delete probe events. This accepts glob wildcards('*', '?') and character
68 	List up current probe events.
77 	Show available local variables at given probe point. The argument
106 	Set the maximum number of probe points for an event. Default is 128.
121 In absence of -m/-x options, perf probe checks if the first argument after
122 the options is an absolute path name. If its an absolute path, perf probe
123 uses it as a target module/target user space binary to probe.

142 'ARG' specifies the arguments of this probe point, (see PROBE ARGUMENT).
