Ooops...sorry....I see others have already explained this.

(FWIW: There's a cute little app that capitalizes on this: "Smart Trash"
(http://www.hyperbolicsoftware.com/SmartTrash.html).)

Well, VAXman-, from reading the man pages for srm it seems that it's
just a little more thorough (srm uses a 35-pass routine by default with
file renaming and truncating) than rm -P.

Unless the DIA is after you, I'd think 3 passes would be secure enough.
But you're absolutely right, srm will do the trick.

However, it seems that Red, the OP, was looking for a GUI since he
didn't respond (yet anyway) to either of our terminal suggestions.

I use Permanent Eraser (a freeware app). I placed its icon on the
finder toolbar. You just drag the file you want to securely
delete to the icon.

If you're comfortable using Terminal, the "srm" command is what you
want. If you're not, others have wrapped it already:
