How do you do ps ax | grep mozilla | awk '{print "kill " $1}'
 

How do you close all open instances of an app using something like :


ps ax | grep firefox | awk '{print "kill " $1}'



You can do the following :





ps ax | grep firefox | awk '{print "kill " $1}' > do_this.sh

chmod a+x do_this.sh
do_this.sh




........., which is what I usually do, but I don't suppose it's the standard way.

pkill firefox-bin

;-)

I've always used:Which one is better?

Well, pkill is more “portable” in the sense that pkill usually does almost the same thing on Linux, Solaris, and BSD. The killall utility of linux is different from the killall utility of Solaris (the latter will attempt to kill all processes on the system—somewhat like the killall5 utility distributed with some linux versions of init).

Interesting. Thanks!
