I have a program called fcc which I use to keep an eye on my Xenix system. It was originally written by Dave Sill , but hasn't been posted to comp.sources.unix yet. I added some additional features (CRC's on files and timestamp checking) that weren't in the original. It's actually two programs - one generates a master list to stdout, the other reads this list and checks each entry. Errors go to stdout. -- Peter Jeremy (VK2PJ) peter@stca77.stc.oz Alcatel-STC Australia ...!uunet!stca77.stc.oz!peter 41 Mandible St peter%stca77.stc.oz@uunet.UU.NET ALEXANDRIA NSW 2015
