Copy a certain file from a CPIO file to a different directory

Question

I am trying to copy a single file from a .cpio file, to a different directory rather than the tree inside it. I am trully sure it is possible, my teacher did it.

I have tried this:

# cpio -i -F backup.cpio sub1/sub2/example.php

But that doesn't extract the file example where I want it to be extracted. I tried adding a third parameter but it doesn't work. Any suggestions? Oh, and I'm running Ubuntu.

One way to do it would be to extract that single file to stdout and redirect it to the file of your choice:

cpio -i --to-stdout sub1/sub2/example.php < backup.cpio > new_filename.php
