Some of the websites that I use to find useful information about command-line commands have copy buttons so the commands can be copied easily.
I thought this was a good idea, so I added one to all the keyboard commands I show that need to be typed in the command line. Now all you have to do is press the copy button 
at the end of the command, and it will be copied so you can paste it into your command-line interface. It’ll look like this:
ls -l
When you press the copy button, it should change to say Copied
, then you can paste it into your command line interface or wherever you like.
