Get to know Linux: ps command

Get to know Linux: ps command: "Over the years there have been certain commands that have really helped me out of a bind. One of those commands is the ps command. The ps stands for process status and it tells you, as you would expect, the status of a process. This is a fast way to know if an application or command is running on a Linux system. Oh sure you could fire up a swell GUI for the same purpose, but that GUI does you no good if you are working on a headless server installation or working on a remote machine. In those instances the ps command is your best bet for helping to manage processes."
