Task Manager on Linux

Task Manager comes with Windows, so it won't be on a new Linux PC. These free apps do the same job, and TuxPick installs them in one go.

Mission Center

Shows what your processor, memory, disks and network are doing.

Installs from Flathub.

A detailed system monitor that runs in the terminal.

Installs from Ubuntu's own software archive.

Press the install button above. TuxPick opens with these apps already ticked. Add anything else you need.
Download the installer file.
Open a terminal with Ctrl Alt T, run the one line TuxPick shows you, and type your password when asked.

It works on Ubuntu 22.04 and 24.04, and on systems built on them like Zorin OS and Pop!_OS.
