Scripts to start and stop

[Bill Larson]

The output from the ps command is being truncated!  I believe that
there is also a "w" option to ps which will include more of the command
argument being reported (and maybe a "ww" also!).  Take a look at the
man page for ps.

Another option could be to modify the nanny.pl command to record the
PID of the nanny command in a file, exactly the same idea as named
writing a named.pid file.  This could be done by adding the following
just prior to the being of the "for" loop:

	open(PID,"/var/run/nanny.pid");
	print PID $$;

This will give you a file, "/var/run/nanny.pid", which contains the
value of the PID of the nanny.pl script that is running.  You can
then use the value reported in this file for the PID to actually kill.
