guys...

as a face saving process... always test what ever you're going to do
when using RM <<< and then substitute ls for rm to see what the
results would be...

and finally, before you do a "rm" .. make sure you have a complete
backup that you can restore from, in the event you really do trash
something up!

jus' sayin!
