killall(1) manual page

The killall utility kills processes selected by name, as opposed to the selection by PID as done by kill(1). By default, it will send a TERM signal to all processes with a real UID identical to the caller of killall that match the name procname. The super-user is allowed to kill any process.

The options are as follows:

-d Be more verbose about what will be done, but do not send any signal. The total number of user processes and the real user ID is shown. A list of the processes that will be sent the signal will be printed, or a message indicating that no matching processes have been found.

-e Use the effective user ID instead of the (default) real user ID for matching processes specified with the -u option.

-help Give a help on the command usage and exit.

-I Request confirmation before attempting to signal each process.

-l List the names of the available signals and exit, like in kill(1).

-m Match the argument procname as a (case sensitive) regular expression against the names of processes found. CAUTION! This is dangerous, a single dot will match any process running under the real UID of the caller.

-v Be verbose about what will be done.

-s Same as -v, but do not send any signal.

SIGNAL Send a different signal instead of the default TERM. The signal may be specified either as a name (with or without a leading "SIG"), or numerically.

-j jail

Kill processes in the specified jail.

-u user

Limit potentially matching processes to those belonging to the specified user.

-t tty Limit potentially matching processes to those running on the specified tty.

-c procname

Limit potentially matching processes to those matching the specified procname.

-q Suppress error message if no processes are matched.

-z Do not skip zombies. This should not have any effect except to print a few error messages if there are zombie processes that match the specified pattern.

Sending a signal to all processes with the given UID is already supported by kill(1). So use kill(1) for this job (e.g.amp; "kill -TERM -1" or as root "echo kill -TERM -1 | su -m <user>").

kill(1), pkill(1), sysctl(3), jail(8)

The killall program was originally written in Perl and was contributed by Wolfram Schneider, this manual page has been written by Jörg Wunsch. The current version of killall was rewritten in C by Peter Wemm using sysctl(3).
