When I used to work for Bluehost I would find myself often wanting to look up DNS information about customers domains to help me diagnose problems. In training they taught us all the flags of host, dig, and whois. That wasn’t good enough for me. I was tired of having to do 3 (at minimum) commands just to find basic information.
This was also around the time I got more interested in programming, so I decided to make it my pet project to learn Bash and automate a part of my job at the same time. This script has undergone many, many iterations to get it to where it is now. Looking at the version history you’d see clearly the dates I learned different tools like case and exec because I’d implement them as best I could.
Below you’ll find an example image of what my script does when executed in the terminal. Probably not useful for many people but it was a learning experience nonetheless.
