This is the first of three videos where I create a dynamic workspace indicator that displays the name (icon) of the current workspace and the total number of existing workspaces.

In this first video, we create a new hook module and create the first version of the script that will output the workspace information.

!!! The getpid script on github is a fixed version. The reason i got multiple pids was because it returned the pid of the getpid script it self.
