With no parameters, it will show all processes. Any parameters that are passed in will be used as an egrep regexp. The procs process will never be shown in the output.

This is very helpful when you want to quickly see if some program whatchamacallit is running. Without a script like procs, the egrep command will always come back as a match for whachamacallit. With procs, if there are no matching processes then you get no output. And the return value of egrep is actually meaningful.
