NAME [Toc] [Back]
killall - kill all active processes
SYNOPSIS [Toc] [Back]
DESCRIPTION [Toc] [Back]
killall is a procedure used by /usr/sbin/shutdown to kill all active
processes not directly related to the shutdown procedure.
killall is chiefly used to terminate all processes with open files so
that the mounted file systems are no longer busy and can be unmounted.
killall sends the specified signal to all user processes in the
system, with the following exceptions:
the init process;
all processes (including background processes) associated with
the terminal from which killall was invoked;
any ps -ef process, if owned by root;
any sed -e process, if owned by root;
any shutdown process;
any killall process;
any /sbin/rc process.
killall obtains its process information from ps, and therefore may not
be able to perfectly identify which processes to signal (see ps(1)).
If no signal is specified, a default of 9 (kill) is used.
killall is invoked automatically by shutdown. The use of shutdown is
recommended over using killall by itself (see shutdown(1M)).
