It's like Windows Task Manager, but for GNU/Linux

Tux Manager

A Linux Task Manager alternative built with Qt6, inspired by the Windows Task Manager but designed to go further - providing deep visibility into system processes, performance metrics, users, and services.

Installing

Debian / Ubuntu / Fedora / EL derivatives (Rocky/Alma/OL)

Use prebuilt packages that can be downloaded from releases

Arch Linux

Install from the official repositories:

bash

sudo pacman -S tuxmanager

Nix flake

Add the following to your flake.nix:

nix

inputs.tuxManager.url = "github:benapetr/TuxManager/";
inputs.tuxManager.inputs.nixpkgs.follows = "nixpkgs"; # optional, deduplicates dependencies

You can then access the package at: inputs.tuxManager.packages.${pkgs.stdenv.hostPlatform.system}.default

Others

You can use an AppImage that can be downloaded from releases or just build it yourself.

Building

qmake

bash

# cd to root of the repo and then:
mkdir build && cd build
qmake6 ../src
make -j$(nproc)
./tux-manager

Translating

To test a different UI locale without changing the system settings, override the process locale when launching the application:

bash

LC_ALL=zh_CN.UTF-8 ./tux-manager  # Simplified Chinese
LC_ALL=cs_CZ.UTF-8 ./tux-manager  # Czech
LC_ALL=C ./tux-manager            # Built-in English

The requested locale may need to be generated or installed on the host system.

Important note regarding AI-assisted translations: Please do NOT submit translations generated "blindly" by AI without review by a native speaker of the language.

Core philosophy and goals of this project

KISS - keep it simple stupid
Lean and clean codebase, minimal system footprint (low RAM and CPU usage)
Stability and reliability, easy debugging
No overengineered or unnecessary extra features
Simple packaging flow - for each packaging tool, there should be a script or 1 line command
Minimal dependencies on 3rd party libs besides Qt so that building anywhere should be trivial
Keep everything well documented
