simple scripting problem

I need some simple syntax that will run "shutdown -y now" when scp is no longer running.

This is what I have so far.

while [ "pgrep scp" != "" ] ; do sleep 2; echo "mooo"; done

Of course this fails to do anything except stop printing "mooo" when scp exits.

Should I be using "case" after the echo?

I'm sure there are 20 ways to do this. I am looking for the most concise way; something I can memorize.

I don't really want a complete solution. I want hints and guidance. I should be able to figure this out myself.

Thanks.

while pgrep scp; do echo "mooo" ; sleep 1; done ; shutdown -h now

I forgot that you could run commands AFTER the "done" statement.
