if you are using ps, you can check the manual
man ps
there is a list of keywords allowing you to build what you need. for example to show, userid / processid / percent cpu / percent memory / work queue / command :
ps -e -o "uid pid pcpu pmem wq comm"
-e is similar to -A (all inclusive; your processes and others), and -o is to force a format.
if you are looking for a specific uid, you can chain it using awk or grep such as :
ps -e -o "uid pid pcpu pmem wq comm" | grep 501
this should (almost) show only for userid 501. try it.
