A scripted approach to grepping what you want out of the ps command...
If you've worked in Unix for any length of time, you're probably familiar with psg or some such variant. Psg stands for "ps through grep" (essentially a ps query whose result is piped grep). It works and works well, but sometimes you need more than just a process string; sometimes you want the process string AND the process ID (PID) separated. Oh yes, and since we're compiling a wish list here, how about the operation simply telling me how many processes match a given target string. I'll show how to do all of that and do it without having to run multiple ps commands and filtering those results through several piped operations.
