cpio is a non-compressed file archive format for Unix-style systems. It was originally intended for tape archiving, similar to the Tape Archive (tar) format.

Contents

Examples

To extract files, using the command line utility:

 $ cpio -idmv -I example.cpio

To list files:

 $ cpio -it -I example.cpio

Identification

A cpio archive begins with one of the following signatures:

  • 0x71 0xC7
  • 0xC7 0x71
  • '0' '7' '0' '7'

Be aware that there are afio extensions to cpio format that are not supported by most cpio utilities. For one thing, if most of the filenames end in ".z", it's probably a compressed afio archive.
