Note

This contains commands shamelessly stolen from many authors. I will try to list all of them at the end of the file, but if I've missed someone, let me know.

Legend

• UC/Use Case : a practical/frequently used example of the command in action (I find it easier to add commands into my daily workflow if I have an example that uses them in something I often do)

The Prompt
