<code>'''killall'''</code> is a [[command-line interface|command line]] utility available on [[Unix-like]] systems. There are two very different implementations.

* The implementation supplied with genuine [[UNIX System V]] (including [[Solaris (operating system)|Solaris]]) and [[Linux]] sysvinit tools kills '''all''' processes that the user is able to kill, potentially shutting down the system if run by root.
* The implementation supplied with the [[FreeBSD]] (including [[Mac OS X]]) and [[Linux]] psmisc tools is similar to the <code>[[pkill]]</code> and <code>skill</code> commands, killing only the processes specified on the command line.

Both commands operate by sending a [[Unix signal|signal]], like the <code>[[Kill (command)|kill]]</code> program.

==Example usage==
Kill all processes named xmms:
<syntaxhighlight lang="bash">
killall xmms
</syntaxhighlight>
