SlackBuildsOrg/office/todo.txt-cli

A simple and extensible shell script for managing your todo.txt file.

After installing the package, copy the default config file to your home
directory and adjust it accordingly, otherwise todo.txt-cli will
misbehave:

$ mkdir ~/.todo
$ cp /etc/todo.cfg ~/.todo/config
$ mkdir ~/todo

Then edit ~/.todo/config:

export TODO_DIR=/home/$USER/todo
