How to Install Taskwarrior (Terminal Based Todo Application)

---

Taskwarrior is an open-source, cross-platform time and task management tool. It has a command-line interface rather than a graphical user interface. If you spend a lot of time on Linux terminal (as a developer or system administrator) then constantly switching to a web app or another GUI based todo applications may not be a very productive thing to do. In that case, you may want to try a simple command line application instead. This article explains How to install Taskwarrior in Ubuntu.
