I was recently moving some s/w via floppy from uport to xenix when I got a rude shock. Cpio works fine (after you get the device names right) as long as you only use a single floppy. Uport cpio handles multiple floppies fine. Xenix cpio exits to shell after writing a full floppy or reading in the first of a multi-volume set. I know about the xenix backup command, but I like the flexibility of cpio. Is it possible to read a multi-volume cpio set of floppies on xenix? (I haven't tried to dd and cat together the files.) This was xenix V2.2.1. -- Internet: asp@puck.UUCP Andy Puchrik uucp: decvax!necntc!necis!puck!asp Moonlight Systems ARPA: puchrik@tops20 Maynard, MA 01754

Tar works on SCO, it's fast, and it's portable all the way back to Version 7. If Microport doesn't have `tar', it isn't UNIX. :-) Unless you have huge files, use the `e' option, which prevents splitting of files across floppies. -- Chip Salzenberg UUCP: "uunet!ateng!chip" or "chips@usfvax2.UUCP" A.T.

What about reading a multi-volume set with the following Bourne-shell commands: while : do dd if=floppydrive bs=blocksize count=blockcount (echo "Mount next floppy"; read ans) >/dev/tty </dev/tty done | cpio [options] Creating a multi-volume set this way is left as an exercise for the reader...
