Re: simple command help

What's the command to use if I want to remove all the directories and files except 'a.gz' under a directory?

There isn't one. If you're using *nix, you could try this: exec('find ! -name a.gz -maxdepth 1 -exec rm -rf {} \;'); Or something like that. If you're on Windows you'll need someone else... :-) -- Richard Heyes Employ me: http://www.phpguru.org/cv
