I've just tried this out on a copy of a tar.gz file - using -s or --sign 
you'll find that the original file is left intact and unaffected.

$ ls
$ gpg --sign test.tar.gz
$ ls

If you've deleted that file, I don't see why GnuPG would be expected to 
replace it. It's done what it can to preserve the signed data even after 
being given a sub-optimal command.

It's times like these when you start to wonder about an undo command for the 
command line - not just the bash history but a complete undo recovery. 


Was there a real situation behind the assumption in the question?
Is there real data that needs to be recovered?
How much time and effort is that data really worth? You can recover most file 
deletions or corruptions if you throw lots and lots of time and resources 
into the mix.
