Finalizing the Cobra-generated Application
Explore how to finalize your Cobra-generated Go command-line application by configuring common options in a YAML file and implementing persistent pre-run and post-run hooks. Understand how to measure command execution time, manage cross-cutting concerns, and improve code ergonomics in your CLI programs.
We'll cover the following...

When generating a lot of commands you often have to repeat the same arguments like license and author. Cobra provides a configuration file where you can set all these options just once.
