So if I'm understanding you corectly, the syntax I'm looking for is: csh> sudo -u $USER nice -15 [scriptname] >& logfile.log &
I am a bit confused on your other point - I read the man page and it states that minus values increase priority such that -20 is highest priority and (+)20 is the lowest. Thanks, -mike On 1/14/07, Rob Sherwood <[EMAIL PROTECTED]> wrote:

So I tried: > sudo nice -15 [scriptname] >& logfile.log & Hiya, First, a quick bit on confusing nice syntax. Not that this is a surprise to you, but what you have up here is correct because you are using csh, where if you had been invoking /usr/bin/nice, it would have *reduced* the priority of your process, where as for /usr/bin/nice you would want "--15". Second, both 'su' and sudo take parameters to exec what ever you want after them with the specified users: sudo -u user ./foo bar or su user -c ./foo bar - Rob .
