I think a lot more portable and robust way to test the feature is to configure git config tar.tar.test.command (or come up with a name for a suffix to be used in the test), point it at a script created in this test script and run git archive with output filename that would trigger the command. Then, arrange the test to notice if the "test" script was called with expected command line arguments and standard input. That way, you do not need to rely on prereqs and you do not have to resort to un-portable use of the "file" command. After all, you are *not* testing if "bzip2 -c" the user happens to have on their $PATH produces output their "find" recognises as bzip2 compressed.
The intent of this test is to ensure `git archive -o something.tar.<format>` produces proper compressed tar archive that can be decompressed with the corresponding decompression tool (such as gunzip for gz files), and not just with `tar xvf`.
