[SOLVED] cpio - How to list files in archive without recursing into directories?

PepperLegs · 04-27-2020, 04:32 AM

Hello! As the title suggests, I'm currently wondering how to accomplish something like this. Let's say I cloned Grub git repo and want to pack it up into a cpio archive. It has a lot of files, and I'd like to see just the archive's folder structure.

Now, with tar I can do something like this:

Code:

tar --exclude='*/*' -tvf grub.tar

Adding more of '*/' to the exclude switch allows me to control the depth of recursion.

Is there an equivalent for the cpio tool? Thank you in advance!

It's more or less the same:

Code:

rpm2cpio qpdf-9.1.0-1.el8.x86_64.rpm | cpio -tv '*qpdf*'

Thank you for your suggestion! Unfortunately, it still seems to recurse into every directory inside the archive. I found bsdcpio though, and it seems to have the option I want.

Code:

bsdcpio -f '*/*' -tv < grub.cpio

This stuff right there seems to do the trick, so I guess it's kind-of solved, hah

GNU cpio has this option, too (-f aka --nonmatching).

Ooh, neat! Thank you again, it works like a charm!

Code:

cpio -tv -f '*/*' < grub.cpio

Alrighty, looks like it's fully solved now!
