alias ps | grep

alias kfire='for i in `ps aux | grep [F]irefox `; do echo $i; kill $(($i)); done; '
This is an attempt to get a command which I can alias. It's ugly but it works. I'm hoping someone can suggest a cleaner version. I have tried.... # alias kfire="for i in $( ps aux | grep [F]irefox | awk \'{print $2}\' ); do kill $; done" # alias kfire=`kill $(ps aux | grep [F]irefox | awk '{print $2}' | tr '\n' ' ')` # alias kfire='ps au | grep -i [F]irefox | awk \'{ print $2 \'} ' and they all fail in a .bashrc I've tried escaping the quotes and can't find a way to make the single quotes ' that awk wants work. Maybe I'm just stubborn but I don't want to put in a little #!/bin/bash file just so I can kill a firefox process all in one stroke. This script works (it kills the process before it errors out)... it's just ugly and there may be a pretty way to do this.

pkill firefox or killall firefox Should work as well an much easier to use.

Careful using 'killall' - its not portable. Under Solaris, this will kill all processes, ignoring the argument.

^following that,if killall is not an option... here's a couple other options: alias kfire="kill $(pidof firefox)" alias kfire="kill $(ps aux | awk '/firefox/ {print $2}' | tr '\n' ' ')"

alias lssd='ps ax | grep -v grep | grep -i firefox | while read pid; do kill "${pid%% *}"; done' this command might be longer but it should handle multiple firefox process without the quoting.
