find and kill a pid for APP

Probably posted previously, I use this all the time to find and kill a process for "APP". Simply replace "APP" with the name of the process you're looking to kill.

kill `pgrep APP`

There's also 'pkill', then you can just say "pkill APP"

a handy trick for removing the grep process from the output of a ps command is to put the first letter of the grepped pattern in square brackets...

e.g. $ ps -ef | grep [A]PP

this removes the need for the third pipeline (your awk)...

pkill and pgrep are all useful things, know them... but they are not always available on the 'more established' UNIX variants...

learn from this website... it's ace for things like this, paste up your command and get suggestions for improvement.

More than one way to skin a cat. I also frequently use 'killall APP'
