    permanently setting niceness of a process?

    I have a process (java) that I want to run at a lower niceness, currently I run 'sudo renice' on the process, but I want a way to automate it.
    I tried making a script which would run 'sudo nice', but then realized that whatever process I run with this command would have that process running as root, which I dont want Java to have root on my system.

    So is there any setting I can change or add that would always run a process at an adjusting nice level?
    Thnx

    I would like to know that trick, as well.

    Thanks!

    I'm thinking out loud here. If you started a shell with sudo nice -1 bash and then run your JAVA process within that shell, would it run at the same nice level as the shell? If that is the case, then you could write a script with the required nice level.

    Please be aware that the actual behaviour of "nice" has changed in recent years depending on the setting of "/proc/sys/kernel/sched_autogroup_enabled".

    For a bit more info see here, which also contains links to other references.
    Any follow-up information on your issue would be appreciated. Please have the courtesy to report back.

    Thanks, just what I needed.
    I got the following to work as I wanted
    Code:
    cmd=`echo "/usr/bin/java $tmp" | sudo nice -n -10 bash -c 'su -lm demon'`

    Thanks, I think I might have to use 'schedtool' instead?
