The idea is great and it works nicely, but only if you are sure that you are the only user of this script. It will not work in a web-server environment or --heaven forbid-- in a mod_perl environment for instance where this same script could be called by more than one client at the same time as it has no protection against such classical race conditions.

I know "multiple concurrent user safety" wasn't part of the specs of this question, but I thought it would be good to give a word of warning here anyhow. I've been bitten before by race conditions when using cook-book (aka cut-and-paste) style programming before.
