("sync; > sync; sync") Actually I saw that documented a very very long time ago in an Intel Unix manual. And Intel got out of Unix in the mid to late 1980s. I don't recall if that was the one that was sold to Kodak - the picture people - which then was sold to Interactive ?? - and eventually wound up at Sun. There were so many Unix variants in those days you had to have a chart to keep up with them. Each HW manufacturer had their own version and name, and at that time the only time you could call your OS Unix was if you compiled it directly from the AT&T tapes with no changes on a Vax [if I recall the scenario correctly]. But that was a long time ago. Bill -- Bill Vermillion - bv @ wjv . com
