- Essentially use pipes:
- cat filelist | cpio -oBcv | compress | dd of=/dev/rmt0
-
- (OK so you may need to put some blocking options on dd, but you should
- get the idea.)
-
- To unarchive:
- dd if=/dev/rmt0 | zcat | cpio -iBcdv
-
- Remember - very few UNIX commands do everything, but they can be
- hooked together easily. I guess the exception is perl(1) and
- probably cpio [-alphabet] :-)
