[Message part 1 (text/plain, inline)]

Hello:

I'm decompressing some very important files as we speak, and while attempting to do so, it returned a warning that "entries after the first were ignored" and failed to output any useful files. The sample usage was:

gzip -d foo.zip

This returned only a single, small, corrupted file called "foo." Now, I only see one entry there, and Googling the problem really didn't help. More to the point, though...the first time I did this foo.zip was deleted. Which is a problem since, as I mentioned, these are important files. Upon further examination, I see that the -k is necessary to prevent this from happening, but I'm surprised that a) default behaviour is to delete files after usage, and b) it would do so even after a warning or error? This latter behaviour is what I perceive to be a bug, above all else, though I find the default behaviour in general to be baffling and unintuitive.

Thanks in advance.

Here's what happened when I tried that with gzip 1.10:

$ gzip -d Java.zip
gzip: Java.zip: unknown suffix -- ignored

and there were no changes to Java.zip.

Perhaps you meant to write 'gzip -d foo.gz'? If so, can you email us a copy of 
your foo.gz file, so that we can reproduce the bug?

OK, thanks, if we can't reproduce the problem I'll close the bug report. We can 
reopen it later if needed.
