I am using Ubuntu 11.10 and am looking for an equivalent to Process Explorer on Linux. There is System Monitor but it's not nearly as good as Process Explorer with all of its detailed information about processes.

Any suggestions?

If you don't mind something that's terminal based, then htop is a good and powerful process manager.

You can install it on Ubuntu with the following command:

sudo aptitude install htop

If you prefer something with a GUI, you could try qps.

You can install it with the following:

sudo aptitude install qps

htop is good , but its not the most user friendly program ! – Gautam May 19 '11 at 4:31

Qps is much better and is easier to use , I just wish it would show the icon of the Process if available , but still its very good – Gautam May 19 '11 at 4:51
Is there tool that can show call-stack of a running thread? – expert Sep 23 '12 at 23:45
It should be noted that Ubuntu 12.04 is the last Ubuntu release that has qps in its default repositories. – karel Nov 2 '15 at 17:20

Use Linux Process Explorer.

Graphical process explorer for Linux. Shows process information: process tree, TCP IP connections and graphical performance figures for processes. Aims to mimic Windows procexp from sysinternals, and aims to be more usable than top and ps.

enter image description here

PS. it is still in alpha development stage.

This looks like a useful tool, but your answer provides very little information about it. Could you edit your answer to include some info about how it works and perhaps a screenshot? – nhinkle Jun 5 '11 at 17:18
This looks great! htop and qps are well-established tools, but they don't display per-process history of CPU and memory usage. The Windows Process Explorer has a lot of useful features that I would be happy to find in a unix tool. – Eldritch Conundrum Oct 20 '12 at 10:40
it lacks sorting or finding a process. if you have tons of processes, you can't locate yours. – Berry Tsakala Feb 25 '14 at 16:45


(although i don't know what the OP needed 3 years ago)

gives almost everything that "top" has, but graphical, sortable columns, find open files, and more.
