shinnai made an interesting comment when I released my tool to find contained files: he wanted to know if I could add a batch mode.

I guess this batch mode is interesting when you want to check if a large set of files contains a particular file. So I added this features and release it here.

Now you can provide more than one containing-file to find-file-in-file.py: you can just type several files, use wildcards and/or use at-files (@file). When you specify @filename, find-file-in-file.py will search in all the files listed in textfile filename (each file on a separate line).

When you provide only one file to search, then this new version will just work like the previous version.

But if you provide more than one file, then batch mode is enabled. In batch mode, the contained file is searched for in each containing file. If a (partial) match is found, it will be included in the report. If no match is found, no output is produced. If you want output even when no match is found, then use option verbose (-v).

Example for a bunch of MSI files:

find-file-in-file.py msi49.tmp *.msi

File: c8400.msi
003a7200 00005600 (100%)
Finished
File: Cisco_Jabber.msi
00295600 00001000 (18%)
00294a00 00000c00 (13%)
00296600 00003a00 (67%)
Finished

File msi49.tmp was found in only 2 MSI files.
