kill

Synopsis

kill [options] IDs

Terminate each specified process ID or job ID. You must own the process or be a privileged user. This built-in is similar to the external kill command, but also allows symbolic job names. Stubborn processes can be killed using signal 9. See the earlier section Job Control.

The command kill -l prints a list of the available signal names. The list varies by system architecture; for a PC-based system, it looks like this:
