killall firefox
I have no idea why you would want to rely on two unusual dependencies to do something that can be done a hundred ways from coreutils...
Kills process by name
It's easy to understand and remember. Need ruby and rush to do this.
pgrep firefox
- this returns the Process ID for the signal firefox
kill -9 pid
- this kills the signal that had the given pid
cmd1 `cmd1` or cmd1 $(cmd1)
- here is the syntax for cmd2 to be executed first. Then the call to cmd2 is substituted with the output of cmd2, and cmd1 is executed.
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
