utility kills processes selected by name, as opposed to the selection by PID as done by
. By default, it will send a
signal to all processes with a real UID identical to the caller of
that match the name
. The super-user is allowed to kill any process.
The options are as follows:
Be more verbose about what will be done. For a single
-d option, 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.
Use the effective user ID instead of the (default) real user ID for matching processes specified with the
Give a help on the command usage and exit.
Request confirmation before attempting to signal each process.
List the names of the available signals and exit, like in
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.
Show only what would be done, but do not send any 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.
Kill processes in the specified

Suppress error message if no processes are matched.
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
. So use
for this job (e.g. “
kill -TERM -1
” or as root “
echo kill -TERM -1 | su -m <user>
IMPLEMENTATION NOTES This
FreeBSD implementation of
killall has completely different semantics as compared to the traditional
UNIX System V behavior of
killall. The latter will kill all processes that the current user is able to kill, and is intended to be used by the system shutdown process only.
EXIT STATUS The
killall utility exits 0 if some processes have been found and signalled successfully. Otherwise, a status of 1 will be returned.
DIAGNOSTICS Diagnostic messages will only be printed if requested by
