kill

kill [options] IDs

Terminate one or more process IDs. You must own the process or be a privileged user. This command is similar to the kill command that is built into the Bourne, Korn, and C shells. A minus sign before an ID specifies a process group ID. (The built-in version doesn't allow process group IDs, but it does allow job IDs.)

Options

-l

List the signal names. (Used by itself.)

-signal

The signal number (from ps -f) or name (from kill -l). With a signal number of 9, the kill is absolute.
