NAME

killall - kill all active processes

SYNOPSIS

/usr/sbin/killall

[signal ]

DESCRIPTION

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 sys-

tem, 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)).
