killall(8)killall(8)NAMEkillall - Terminates all processes started by the user, except the
calling process
SYNOPSIS
/usr/sbin/killall [- | [-]signal_name | -signal_number]
/usr/sbin/killall -l
OPTIONS
The hyphen character (without an argument) sends a SIGTERM signal ini‐
tially and then sends a SIGKILL signal to all processes that survive
for 30 seconds after receipt of the first signal. This gives processes
that catch the SIGTERM signal an opportunity to clean up. A signal
name, optionally preceded by a hyphen, sends the specified signal to
processes. The hyphen character (with a signal number argument) sends
the specified signal, either a name, stripped of the SIG prefix (such
as KILL), or a number (such as 9). For information about signal names
and numbers, see the signal() system call.
In the System V habitat, the optional signal number does not
have to be preceded with a hyphen (-). Lists signal names in
numerical order (as given in the /usr/include/signal.h file),
stripped of the common SIG prefix.
DESCRIPTION
This command provides a convenient means of killing all processes cre‐
ated by the shell that you control. When started by the superuser, the
killall command kills all processes that can be terminated, except
those processes that started it, the kernel processes, and processes 0
and 1(init).
Security Configuration
This command is modified in all security configurations of the system.
EXAMPLES
To stop all background processes that have started, enter: killall
This sends all background processes signal 9 (the kill signal,
also called SIGKILL). To stop all background processes, giving
them a chance to clean up, enter: killall-
This sends signal 15 (SIGTERM), waits 30 seconds, and then sends
signal 9 (SIGKILL). To send a specific signal to the background
processes, enter: killall-2
This sends signal 2 (SIGINT) to the background processes. To
list the signal names in numerical order, stripped of the SIG
prefix, enter: killall-l
This displays a list of signals, which may vary from system to
system.
