execsnoop - snoop new process execution. Uses DTrace.
execsnoop [-a|-A|-ejhsvZ] [-c command]
execsnoop prints details of new processes as they are executed. Details such as UID, PID and argument listing are printed out.
This program is very useful to examine short lived processes that would not normally appear in a prstat or "ps -ef" listing. Sometimes applications will run hundreds of short lived processes in their normal startup cycle, a behaviour that is easily monitored with execsnoop.
Since this uses DTrace, only users with root privileges can run this command.
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.
execsnoop will run forever until Ctrl-C is hit.
