| * ''pgrep'' : Works like the unix ''grep'' command but instead of texts and string it works with processes. ''pgrep emul*'' will obtain all PIDs of processes containing the word **emul** - this usually obtains the PID of the binary of EmulationStation but also it's wrapper script. | * ''pgrep'' : Works like the Unix ''grep'' command but instead of text and strings it works with processes.
