I'd like a snappy GUI-based (I insist since people still want to propose console-based) application that can show me running processes and allow me to kill them, on Linux. It doesn't need to be as powerful as Window's Process Explorer or even Win7's Task Manager. Is there something lightweight and functional?

I'd appreciate a recommendation.


Look at htop. It's light and it'll do what you want. Yes, it does launch in a console, but you can interact with it using the mouse, it's colored, it's live/animated, you can click on column headers to sort, scroll with the mouse, and anything else you care to try.

    Who said it was an obsession? Who said it's specifically for me? This site is not for discussing what is asked. – fury Jan 2 '12 at 5:05

    Well, you can select the right answer. If people think its a good one, it'll still get upvoted. I'm still digging for something closer to your needs, but they all seem to be large DE specific things, or 200 years old. – Journeyman Geek Jan 2 '12 at 5:33

    -1 for pointless soapboxing. +1 for offering a different option. -1 for that option not doing what the OP wanted (integrated ablity to kill processes) – Wesley Jan 2 '12 at 6:44

    @Wesley, press k in htop. It does have the ability to kill processes. – user1686 Jan 2 '12 at 8:47

    @WesleyDavid not knowing that htop can kill doesn't mean htop can't kill. Fury: this site is precisely for discussing what was asked. And a command line GUI is still a GUI. – Mahmoud Al-Qudsi Jan 2 '12 at 17:38

There's Linux Process Explorer, a process management tool which seeks to mimic the functionality of Process Explorer for Windows.

Most GUI distros include a basic process management tool among their default system tool set.

  • I use CrunchBang Linux (Debian-based) and there is nothing but top. This distro lets users choose what they want :) Thank you for the link, looks interesting. – fury Jan 2 '12 at 4:18
  • However it's 14MB and in python. Not lightweight, but looks powerful. – fury Jan 2 '12 at 4:25
  • If you don't mind a terminal-only app then have a look at htop. – Andrew Lambert Jan 2 '12 at 4:28
  • Thanks, but as stated in my question, for this app I would like a GUI. – fury Jan 2 '12 at 5:00

So here is what I finally found, LXTask.

  • Lightweight, simple
  • Monitors processes
  • Can kill processes
  • Real GUI

There is also the GNOME system monitor, which also displays the process commandline. It is much more resource hungry though...

  • That is shiny. Don't forget to self select that as the answer when you can ;) – Journeyman Geek Jan 2 '12 at 22:57
  • Will do. I wonder why I can't, and will I ever be able to do it that soon after a question? – fury Jan 3 '12 at 1:43
  • meta.stackexchange.com/questions/5234/… 48 hours minimum. I just tend to remind newish users cause answered/non selected questions tend to bounce back up, and i wanted to express that it was shiny, and i needed more words to get past the lameness filter ;p – Journeyman Geek Jan 3 '12 at 3:43
  • Gnome System Monitor actually uses less memory than lxtask, ~10mb after opening compared to ~19mb for lxtask. Admittedly this is a few years after your Q/A so GSM will have improved while lxtask doesn't get updated much any more. – Charles Goodwin Jan 28 '15 at 11:13

There is also conky. It is not a process monitor, but system monitor which can show quite a lot of information about your system with quite many different themes. Plus it is light and done specifically for Linux. Additional themes you could download from here.

XFreq provides some Widgets to display the frequencies (including turbo boost), the temperatures, C-States and other features of the Intel Core i7 processors. It is also programmed for Core 2 and other Intel architectures. http://code.google.com/p/xfreq

I like MATE system monitor, it's a nice GUI with more versatility than GNOME system monitor.
