Dear reader,

Could someone tell me whether it is possible to set an
environment variable or otherwise to automatically renice
background processes to low priority.

This would need to trap backgrounding from the command line
using '&' and also using ctrl Z followed by 'bg'.

We want to enforce running background jobs at low priority
but people are reluctant to conform.

Many Thanks

Many moons ago, a man posted to comp.unix.admin, saying:

And Neil W. Rickert responded:

If that doesn't settle it, you're going to have to contact Simon
Travaglia.
