The cpio application accepts input filenames via stdin and it writes the archive to stdout. We have to redirect stdout to a file to save the cpio output:

1. Create test files:

        $ touch file1 file2 file3

2. Archive the test files:

        $ ls file* | cpio -ov > archive.cpio

3. List files in a cpio archive:

        $ cpio -it < archive.cpio

4. Extract files from the cpio archive:

        $ cpio -id < archive.cpio
