There's a lot to learn about image files on the command line, from verifying file format to finding out where and when photos were taken and maybe even getting an unusual view of what they look like.
Linux has over 1,000 commands on a basic service. When you migrate to the desktop, that number grows. For example, in /usr/bin on Pop!_OS there are 1,615 commands, and in /usr/sbin, there are 609.
When was the last time you had to create a zip file? Personally, I have to interact with those types of files all the time (either receiving or sending them to various clients, family, and friends).
