killall sends a signal to all processes running any of
the specified commands. If no signal name is specified, SIGTERM
is sent.
Signals can be specified either by name (e.g. -HUP
) or by number
(e.g. -1
). Signal 0
(check if a process exists) can only be specified
by number.
If the command name contains a slash (/), processes executing that particular file will be selected for killing, independent of their name.
killall returns a non-zero return code if no process has been killed for any of the listed commands. If at least one process has been killed for each command, killall returns zero.
A killall process never kills itself (but may kill other killall processes).
The behaviors specified in this section are expected to disappear from a future version of the LSB; applications should only use the non-LSB-deprecated behaviors.
