Installing task warrior in Ubuntu

Taskwarrior is a command-line todo list manager.

In a world with a lot of virtualized and remotes servers, we need a Post-It alternative ;-)

To install Task Warrior, execute:

sudo add-apt-repository ppa:ultrafredde/ppa
sudo apt-get update
sudo apt-get install task


Quick steps in task:

List tasks
task

Add a task
task add "task to do"

Add a note to a task
task #n annotate "a note"

Done a task
task #n done

There are a lot of commands, you can found them at task warrior wiki


Example:


task
[task next]
