If I can get some feedback on it I'll try to make it into a proper port. For now, it is self-contained; just type "cdbackup" when you get it and put it where you want it to live and it should "install itself." Use the -h option for help. Let me know if you have any questions. And if others want to try it out, let me know. It's 70K, so I'm going to send it just to Marco (and any others who request it), not to the entire list. It support incremental backups; it does not support appending to an open CD, though I could consider adding that in the future, I suppose. In my case my problem is that I have far more files than there is a spaced on a CD, rather than vice-versa, so that's the problem it's mainly meant to solve. -- Brian, the man from Babble-On . . . . bts@babbleon.org (personal) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
