I have one for CPIO Andy Tanenbaum wrote something like this for Minix vol [-u] size device It splits up stdin onto multiple disks or joins them together on stdout. Works with "anything". A few things that would be nice to add: disk sequence numbers (this may have been) and the ability to detect EOF on a device rather than specifying the size. A CRC per disk would be nice, too. The problem: what do you do when disk 3 of a 20-part disk set goes bad? I remember a "badtar" program that could resync and recover the rest of the tar file. Glen Overby
