killall is a UNIX utility that sends a signal to all processes that were started by the specified command . If no signal name is specified, a SIGTERM signal is sent .
Signals can be indicated both by name (for example, - HUP ), and by number (for example, -1 ). Signal 0 (check if the process exists) can only be indicated by a number.
If the command name contains a forward slash (/), then only those processes that execute the specified file will be selected for completion, regardless of their name.
killall exits with a non-zero return code if no process has been terminated for any of the listed commands. If at least one process has been completed for each command, killall returns zero.
killall never terminates its own process (but may terminate other processes launched by the killall command).
Options
- -i
- Ask for confirmation of completion of processes.
- -l
- Print the names of all known signals.
- -v
- Notify if a signal was sent successfully.
