kill linux command

kill

kill [option] IDs

This is the /bin/kill command; there is also a shell command of the same name. Send a signal to terminate one or more process IDs. You must own the process or be a privileged user. If no signal is specified, TERM is sent.

Options

-l

List all signals.

-p

Print the process ID of the named process, but don't send it a signal. To use this option, specify the full path (e.g., /bin/kill -p).

-signal

The signal number (from /usr/include/sys/signal.h) or name (from kill -l). With a signal number of 9 (HUP), the kill cannot be caught by the process; use this to kill a process that a plain kill doesn't terminate. The default is TERM.
