Equivalent of grep -l for filenames in zipfile

Question

Given a set of zip files, is there an easy way to list only those zipfiles that contain files whose names match a given pattern, cf. using grep -l to list only files whose contents contain lines matching a given pattern?

The best I've been able to come up with is

for i in $ZIPFILE_LIST
> do j=$(basename $i)
> unzip -l $i > /tmp/$j
> grep -l $PATTERN /tmp/$j
> rm /tmp/$j
> done

but it's fairly hacky and without e.g. passing the grep output through sed (with various escaping headaches) it's going to tell you which files you care about, but it's not actually going to give you the full paths in a form you can then pass on to something else. It seems like this is a reasonably common use case and there ought to be some better out-of-the-box tool or combination of tools to do it.

Yes, that's pretty much what I said in the question. – David Moles Jun 02 '14 at 16:49

I think you want zipgrep, which is installed in stock Ubuntu (so maybe installed on your system). It's a shell script that uses unzip and egrep internally.

See comments on [Iain's answer](http://serverfault.com/a/599810/39209) -- I'm not looking for matching files, I'm looking for matching filenames. – David Moles May 30 '14 at 22:58
Have you tried `zipgrep -l`? It works for me. Sorry if I didn't spell it out. – Chris Lear May 31 '14 at 08:16
I realise that this doesn't match your description ("contain files whose names match a given pattern"), but I think it matches your code, and your `grep -l` example. – Chris Lear May 31 '14 at 08:17
It doesn't, because I'm not unzipping the zipfiles, I'm just listing their contents (`unzip -l`). – David Moles Jun 02 '14 at 16:50

Would the Python zipfile module help solve your problem?

eg:

import zipfile

def findfileinzip(source_filename, pattern):
    print(pattern)
    zf = zipfile.ZipFile(source_filename,'r')
    for member in zf.namelist():
        if member.find(pattern) != -1:
            print(member)
