pidof finds the process ID of a running program. A good way to understand things is to try them out: go to your command shell and execute "pidof sh" or "pidof bash".
In a script, you could use "$$" to get the Process ID of the script instance but pidof has the extra advantage of giving you *all* process ids of instances of the script.

killall5
KILLALL5(8) Linux System Administrator's Manual KILLALL5(8)
NAME
killall5 -- send a signal to all processes.
SYNOPSIS
killall5 -signalnumber [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..]
DESCRIPTION
killall5 is the SystemV killall command. It sends a signal to all processes except kernel threads and 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.
OPTIONS
-o omitpid
Tells killall5 to omit processes with that process id.
NOTES
killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program.
EXIT STATUS
The program return zero if it killed processes. It return 2 if no process were killed, and 1 if it was unable to find any processes
(/proc/ is missing).
SEE ALSO
halt(8), reboot(8), pidof(8)
