Demo of TMR (my timer for the terminal)

Raw link:

In this screen cast, I present a working prototype of TMR (TMR Must Recur). This is a shell script written in Bash that implements a simplistic timer. tmr is meant to be executed in the console and accepts a single argument that must be a valid unit of time, such as 10s for ten seconds.

The purpose of this script is mostly didactic. It tries to do things by using Bash parameter expansion. Ultimately, this is just an experiment meant to explore the possibilities of various shell scripting methods.

TMR is part of my dotfiles and is licensed under the GPLv3 (as is the rest of the code).
