IMHO, killall is a terrible script to use since it's behavior is so
different on different machines. I've seen newbie sysadmins do bad
things with killall on my Solaris machines: Here is the start of
Solaris' manpage:
DESCRIPTION
killall is used by shutdown(1M) to kill all active processes
not directly related to the shutdown procedure.
killall terminates all processes with open files so that the
mounted file systems will be unbusied and can be unmounted.
killall sends signal (see kill(1)) to the active processes.
If no signal is specified, a default of 15 is used.
As you can see, when they type 'killall netscape' when they are r00t,
everything gets killed.
