Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
pkill -x firefox

Or even easier, if it's available:

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...

rush> processes.filter(:cmdline => /mc/).kill

-9

It's easy to understand and remember. Need ruby and rush to do this.

kill -9 `pgrep firefox`
2010-05-02 23:05:25
User: dustindorroh
Functions: kill
-11
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.

Know a better way?

If you can do better, submit your command here.

What others think

_BE Careful_ with where you run this `killall` - in Sys V (i.e. Solaris), this does what it says - /kill/s /all/ processes owned by you. If run as root, that includes init :

--snip from man(1M) killall/sol10--

NAME

killall - kill all active processes

SYNOPSIS

/usr/sbin/killall [signal]

DESCRIPTION

killall is used by shutdown(1M) to kill all active processes

--/snip--

Don't do that on HP-UX. :)
