WARNING, WARNING.

If you try killall on a non-Linux system you might be very surprised Smilie It often has a more, well, literal meaning.

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME
killall5 -- send a signal to all processes. SYNOPSIS
killall5 -signalnumber [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] DESCRIPTION
killall5 is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d directory. OPTIONS
-o omitpid Tells killall5 to omit processes with that process id. NOTES
killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program. EXIT STATUS
The program return zero if it killed processes. It return 2 if no process were killed, and 1 if it was unable to find any processes (/proc/ is missing). SEE ALSO
halt(8), reboot(8), pidof(8) AUTHOR
