Especially when checking for the existence of a process running... For example: # ps -xwa | grep process-name | grep -v grep This will remove the grep process itself from the resultant output... Ie. # ps -xwa | grep process-name will give the output: 5123 process-name 7843 grep process-name Whilst the former command will only output the first line.. And lets not forget the gnu tools of cut, paste, split and sort are fantastic - very great for text manipulation and hunting through logs. All the best...
