Taskwarrior is an open-source, cross platform time and task management tool, used to keep track of and handle tasks. It uses a command-line interface, although since its inception, graphical user interface wrappers have also been created.

Taskwarrior uses concepts and techniques described in Getting Things Done by David Allen, but is paradigm-agnostic in that it does not require users to adhere to any given life-management philosophy.³

According to its author, Taskwarrior was created "to address layout and feature issues"⁴ in the Todo.txt applications popularized by Gina Trapani.⁵ The authors offer an accompanying tool called Timewarrior for tracking time spent on projects.⁶ Configuration allows e. g. to define recurring breaks such as lunch time.⁷ The documentation notes that "Timewarrior focuses on accurately recording time already spent, whereas Taskwarrior looks forward to work that is not yet done."⁸

Taskwarrior's source code is a free and open-source software and can be either compiled from source code to run on a variety of architectures and operating systems, or installed as a binary, which is available on many Linux distribution binary repositories.

Taskwarrior comprises three main commands: add, list, and done. All other functionality – recurrences, tags, priorities, etc. – are optional.

$ task add Pick up keys to the new apartment
Created task 1.

$ task list
