The Terminal, (AKA CLI, or “Command-Line Interface”) is super-powerful and allows you to interface directly with the underlying workings of your operating system. It’s pretty essential you learn how to use the Terminal if you’re going to be developing software or doing any more advanced operations within your operating system as many operations are done exclusively through the Terminal. In this post, I’ll give you a quick run-down on how to navigate your file system in Terminal.
If you ever felt like you’d like to customise and change the standard icons of any app, file, or folder on macOS, but you didn’t know how, you’ve come to the right place. It’s actually very easy, and can be done in just a few very simple steps. You first need to find and download an icon of your choice. I recommend the site IconArchive, they have many high-quality icons.
