[TxMt] TextMate position files and command line tools question

Hi all,

When I "tar" up a TextMate project directory, I get a ._<filename> file for each file I've opened in TextMate. I've had a look at one of these files on another system, and it appears to contain TextMate's last caret position information for the related file. The problem is that I can't seem to exclude these files from the tarchive using the --exclude or --exclude-from parameters to "tar". Further, if I try to use "find" to generate a list of the ._ files, the ._ files are never in the list. Similarly, they don't show up in the output of "ls", and can't be deleted with "rm".

Has anyone been able to successfully exclude these files from "tar"? Is there any way to delete them?

Thanks, Chris.
