When writing shell scripts, you should always aim to make sure the code is as readable as possible. When you're in the process of creating a script, all the logic, commands, and flow of the script will be obvious to you, but if you look at the script after putting it down for a little while, this isn't a given anymore. Even worse, you'll most likely work together with other people on scripts; these people have never had the same considerations you had when writing the script (and the same goes for the other way around). How can we promote better readability in our scripts? Comments and verbosity are two ways in which we can achieve this.
