Re: [MLUG] tar no destruct?

Hehe, I completely skipped that one, thinking it was for keeping tar 
from clobbering files when you extracted an archive, but I just tested 
it, and it keeps you from clobbering an archive when creating one that 
already exists, too.

The only problem is that it just immediately returns, with no messages 
or anything, so you may think you've backed something up, and it didn't 
happen because the archive already was there.
