Yep, exactly as I remembered it. But -u didn't seem to be working. It turned out to be a "very" minor difference in the lines, in a very large file. The first two places I looked were "man sort", and "info sort". Both said that -u should work. I suspect that it does. The fault may have been mine on this one. Thanks!

To remove duplicates, you can do "sort out.file" or "sort -u out.file". Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

I never used sort and I only have the german man page. so you want to check man sort yourself to be sure. wobo -- "... and anyway, an html can't carry a virus."
