Recently I discovered console based task manager – devtodo. It is very useful tool as you can easily use it over SSH connection, create multiple different lists and combine them together. I will shortly describe devtodo utility available in Debian package repository but you need to know that you can use newer version – devtodo 2.
Add new task
List tasks
Edit task
Select different database
Mark task as done
View done tasks

Unset done flag

There are more interesting possibilities so try it yourself. I am sure that you will enjoy it as much as I do.
