The tests check that the filesystem_walk command is able to retrieve
information regarding both existing and deleted files.

A NTFS image is used as Ext3+ filesystems deletion is more aggressive
in terms of metadata removal.

This is a bit unreadable, a better approach is to read commands from
stdin; see for example fish/test-copy.sh.

Hmm are you sure this works when tracing is disabled?  The default
output in guestfish for structs is each field in a single line.

I tried it without tracing and it works as well. Just to be sure, I'll add the -z flag to grep to ignore newlines.


Unless you compare the whole output like other tests do, a better
solution could be write this test using a scripting language like Perl:
I think most, if not all, of the non-bash tests are Perl-based, and it
would allow to do better checks for the return values.
I'm not familiar with Perl therefore it would require a bit more of time for little value.
I could do it in Python but I believe bash for such simple cases is way more readable and effective.

Thanks,
