Package: cpio Version: 2.6-17 Severity: normal In the info page, we have the following switches defined for the various modes:
`-i, --extract'
Run in copy-in mode
`-o, --create'
Run in copy-out mode.
`-p, --pass-through'
Run in copy-pass mode.
While I think copy-in and copy-out are the opposite of what I think they
logically should be, the problem is with the --sparse option and it's
description. Either the info page is wrong or `cpio` is 'slighly
broken'.
The info page states:
`--sparse'
Write files with large blocks of zeros as sparse files. This
option is used in copy-in and copy-pass modes.
...but in practice that's not the case..
darkside:/bin# ls |cpio -o > /tmp/cpioarchive
7976 blocks
darkside:/bin# cpio -i --sparse < /tmp/cpioarchive
cpio: --sparse is meaningless with --extract
...and contrary to what the info page states, --sparse is accepted in copy-out
mode:
darkside:/bin# ls |cpio -o --sparse > /tmp/cpioarchive
7976 blocks
