Where do I add nohup and & to put this in the background?
I tried multiple places and had no luck.
find . -links 2 -type d |
xargs -I{} -P 5 -n 1 bash -c 'cd "{}" && run_script.sh'

Simplest answer - just put it at the end of the line.
find . -links 2 -type d | xargs -I{} -P 5 -n 1 bash -c 'cd "{}" && run_script.sh' &
That effectively puts the pipeline in background.
You're probably going to want to manage your i/o though.

-P 5-nshould probably be-P 5 -n. You can put thenohupin front of thefind.– tripleeeCommented Jul 22, 2021 at 13:54 -
Yeah, I had to fix that in my test and forgot to fix it here. Thanks. Commented Jul 22, 2021 at 14:45

run_script.sh is long running process. It is terminating even if find is in the background– TimsCommented Jul 22, 2021 at 15:06

maybe what you need is
cd "{}" && nohup run_script.sh &'. That will thow anohup.out` in every directory, but your output (if any) will be clearly associated with the relevant location. You could manage your own redirections if you wanted. Make sure here is useful logging, even if it's just turning on debug mode withset -xinsiderun_script.sh. Commented Jul 22, 2021 at 15:30
bash -c 'cd "{}"...will break on", Use arguments -xargs -n1 bash -c 'cd "$1"' --
