Killall

The killall command kills processes by name of the command being run, alleviating the need to run ps to find the pid before issuing a kill command. Signals other than the KILL (a.k.a. SIGKILL) signal can also be sent.

Caution should be used on non-Linux systems, where killall may have a different behavior, like killing all processes attached to the current terminal.

Example
$ killall mozilla-bin Kills a locked-up Mozilla browser.
