I can personally vouch for cp, mv, gzip, cat, and grep :) There was a little problem with tcopy and dd several years ago as they wrapped at 4G. That's fixed. I used to move tape images around a lot with FreeBSD 2.2.5. Not a bit of problem with huge files other than the counters in dd and tcopy. The only real problem I had was SGI's love of 128k blocksize on DDS tapes. FreeBSD can't do that. But in the business I was in I couldn't send out a tape in any format that everything I knew of could read so the SGI tapes needed to be fixed in spite of our policy of being a library and not modifying submissions. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
