If you don’t know about shell aliases, then in this short article I’ll explain what they are for and why to use them.
Alias is basically the same thing but with a different name. Alias is just a shortcut. In this case you’re making a shortcut for certain shell command.
Why to type three-word command if you can just use two or three characters?
Unless you use these new GUIs for everything, you’re used to working with terminal for various tools, version control, frameworks and so on. And you have to type same things pretty often. Maybe too often.
