KILLALL(1) General Commands Manual KILLALL(1) NAME killall -- kill processes by name SYNOPSIS killall [-delmsvz] [-help] [-I] [-j jail] [-u user] [-t tty] [-c procname] [-SIGNAL] [procname ...] DESCRIPTION The killall utility kills processes selected by name, as opposed to the se- lection 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 match- ing 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 ex- pression against the names of processes found. CAUTION! This is dangerous, a single dot will match any process running un- der 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 sig- nal may be specified either as a name (with or without a lead- ing "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. ALL PROCESSES 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. "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 lat- ter 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. EXAMPLES Send SIGTERM to all firefox processes: killall firefox Send SIGTERM to firefox processes belonging to USER: killall -u ${USER} firefox Stop all firefox processes: killall -SIGSTOP firefox Resume firefox processes: killall -SIGCONT firefox Show what would be done to firefox processes, but do not actually signal them: killall -s firefox Send SIGKILL to csh process running inside jail ID 282: killall -9 -j282 csh Send SIGTERM to all processes matching provided pattern (like vim and vimd- iff): killall -m 'vim*' DIAGNOSTICS Diagnostic messages will only be printed if the -d flag is used. SEE ALSO kill(1), pkill(1), sysctl(3), jail(8) HISTORY The killall command appeared in FreeBSD 2.1. It has been modeled after the killall command as available on other platforms. AUTHORS The killall program was originally written in Perl and was contributed by Wolfram Schneider, this manual page has been written by Jorg Wunsch. The current version of killall was rewritten in C by Peter Wemm using sysctl(3). FreeBSD ports 15.quarterly June 27, 2020 KILLALL(1)
