How to list all background pids in bash

0 votes

Either I am not able to phrase my search correctly or the answer is not easy to find!, but I am trying to figure out how to list all of my background task PIDs. For example:

So far I have found that to list the last PID we use:

$!

But now I want to list the PID of the task before that (if one exists), but I can't find how to do that. Utlimatly I want to list all my background task PIDs.

I know we can also find last job ID with:

%% (last job in list)
%1 (first job in list)
%2 (second job in list)

But the same does not seem to work for process id?

Thanks all :)
