I've received a Unix software distribution as a compressed cpio file. What's the best command to extract the files?

When you did man cpio what did you see? –  S.Lott Aug 28 '09 at 0:56

gzip -cd foo.cpio.gz | cpio -idmv
  • i : extract (input)
  • d : create directories
  • m : preserve mtime
  • v : verbose

This Wikipedia page on cpio has some good notes.
For more details, refer to the cpio manual.

A link from the same Wikipedia page discusses comparison with tar archives.
And, here is an example of using cpio with the tar format.
