killall5(8) -- Linux man page
NAMEkillall5 -- send a signal to all processes.
DESCRIPTIONkillall5 is the SystemV killall command. It sends a signal to all processes except the processes in its own session, so it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d directory.
