Step by step guide on using some basic commands in Linux

Here's a website that will teach you to make use of commands and it'll teach you what they do and what they're meant for:

If you're not satisfied with the information the website it providing you with the commands. Just type in:
man [command name - i.e. find or file]
Man being short for manual, it'll teach you how to use the different commands, and all the different things that you can or could do with 'z' command. If all else fails, just Google something or post something on here or Reddit/r/Linux, I'm sure you'd find the help you're looking for eventually.

I'm a beginner myself and using this helped me a hell of a lot.
