ps and nice questions (Process priority)

[RnAoDm]

Hello fellow Linux users,
this is my first post here and I'm happy to be a part of these forums.
I have a few very specific questions that I would like help with if anyone could try and give me a hand.

I am currently using the ps command with options "ps -eo pri, ni, cmd", I would like however to display the output form the highest to lowest priority. I can not however figure out how to do this, I have searched all over the place!

Another question, say for example I have a process and I would like to decrease the priority of that process by 10 (without knowing the original priority). Can this be done?

Thank you very much, any help is appreciated!

ps -eo pri,ni,cmd | sort -n
or
ps -eo pri,ni,cmd | sort -nr

will sort, or sort and display in reverse, the output, you may need to make it

ps -eo ni,pri,cmd | sort -nk 2 (or sort -nrk 2)
to sort using the 'ni' field (the 2nd colomn).


as for changing the niceness of a process, you can use renice as root. I have no idea what priority is, so I can't help you there.
