System monitor in Kubuntu can filter running processes so that I can choose Program only choice so my question is how can I get the same results by commands ?

  • Take a look at the man pages for top or ps: man top or man ps. htop is a nifty program to have installed, as well. – Ray Sep 18 '18 at 4:02

    It's not an unreasonable question to ask! – DK Bose Sep 18 '18 at 4:09
  • @Dk Bose I am trying to build an app that can collect information about the time spent by the user on those apps , so what I want is how can list them that's it – Kirollos Nasr Sep 18 '18 at 4:18

    @KirollosNasr That's not easy to do. Many programs are running in the background and the system doesn't distinguish (as far as I know) between whether a program is doing work or whether a user is actively using it. The nature of some programs is to not have a user do anything interactively -- but it's still doing something useful behind the scenes. – Ray Sep 18 '18 at 8:15
  • @Ray Thank you for your reply , I think the answer here can help me , it shows that we can recognize the processes I mean , they are initiated from a .desktop which I could trace. Although there are some exception that I think I could handle them – Kirollos Nasr Sep 18 '18 at 21:08
