Limit CPU usage of process

Lunar_Lamp · 06:13 AM

I wrote a script to convert a few thousand music files from one file to another, and have started it going and don't want to stop it now really. However, after leaving it running for a while I realise that I forgot to start it with the 'nice' command, to make it have a low priority on CPU usage. Is there a way to lower a processes priority once it has started?

The script uses lots of sequential ffmpeg instances, and each one has a different PID, so I suspect this may not be possible. Also, would the 'nice' command have done what I wanted it to do seeing as the script itself doesn't do much, other that tell ffmpeg which files to convert. That is, it's ffmpeg that is using the resources. Or does 'nice' make all the children of a script have the same priority as the parent process?
