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

    It should be noted that Ubuntu 12.04 is the last Ubuntu release that has qps in its default repositories.

    @karel It is currently supported, and in the default repositories.

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?

  • 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. Oct 20, 2012 at 10:40
  • it lacks sorting or finding a process. if you have tons of processes, you can't locate yours. Feb 25, 2014 at 16:45
  • @BerryTsakala typical linux programmers will write a process explorer without even the basic features of windows task manager! anything a linux programmer does with a gui, is a gimmick, i'm sure they dont even use what they write!

(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.

Few screenshots:

  • Better sudo apt-get install ksysguard.
