Linux terminal command reference

I'm aiming this article mostly at absolute beginners to Linux, as I feel the guidance resources available for a Windows user switching to Linux on their own are woefully inadequate right now. It's meant to be read after the Ubuntu command-line tutorial.

There are lots of places that list "the basic" terminal commands, but I've never seen one of those references that lists enough of them to really show how awesome the terminal is to someone who hasn't seen it. I'll sort the commands within each category from most to least important.

I believe the story behind this command's name is that first there was `more`, which did this job and was called so because it lets you see *more* than your screen can fit, and then somebody wanted to make a better version of it and called it *less*. Nowadays, `less` has basically replaced `more`.

Dealing with compressed files

If something has a `.zip` extension, the command to unzip it should be `unzip`. If `.gz`, it's `gunzip`. If `.tar`, `tar xf filename` (the `xf` stands for "extract file").
