Mumaugh) Distribution: net Organization: ATT Computer Systems Center, Lisle, Ill. Lines: 16 Summary: Yes you can setup login to give a set of priorities to users. On a system many years ago we had the default nice as 2 set in the code of login just before we ran the user's shell. Then we set some programs such as cc and n/troff to a nice of 3 and the editors [RAND and VI] to a nice of 1. You can do some sort of variation on that. If you assign a different nice to a given user, then the changes to n/troff, cc and the editors need to calculate a "relative" change to the current nice. Warning: small changes to nice can have powerful effect. We niced a program at 5 once and it took 6 hours to run. Dennis Mumaugh Computer Systems Center Lisle, Illinois
