Want to kill current process then restart

[Brian]

I have a perl/tk app where I want to supply a button that will kill
the current process and then restart the application. I was thinking
that I could just fork off a child process at start time and then wait
for the child to finish and then fork off another child. The quesion
is how to go about doing this?

Thanks,
brian

Assuming that $0 hasn't been modified and is available from the CWD:

exec $0;
