[olug] Unix Tip: MOVING FILES WITH CPIO

[drose.SCANTRON at scantron.com]

1.  In the old days you could not copy files across file systems.  Using
tar or cpio was the only way that you could copy files.  I have not used
this method in a long time.

2.  CPIO is needed in older unix's.  TAR will not backup 0 length files,
but cpio will.  I use CPIO on a daily occurrence to backup and restore
systems.

Whats the big purpose with using cpio, why not just "cp -xpvr /old /new"?

       -x, --one-file-system
              stay on this file system
       -p     same as --preserve=mode,ownership,timestamps
       -R, -r, --recursive
              copy directorie
       -v, --verbose
              explain what is being dones recursively  ?? necessary?

What does cpio buy you?  Does anyone ever use it? =)
