Terminal Todo Managers
A todo manager keeps a running list of things to do and marks them off. Each entry is a line of text with a state, sometimes a tag or a due date, stored in a plain text file or a small local database that syncs or sits in version control.
In the terminal an item is added, completed or dropped with one command, or the list is shown in a TUI with keys bound to the same actions. Taskwarrior and the todo.txt format are the two conventions most of these tools read and write.
Boards, projects and scheduled work are under task managers, and longer prose is under note taking.
Below is a list of terminal tools that keep todo lists.
