Now, when we talk about “fundamentals,” what we mean is learning how to use basic commands in a terminal window. This might sound intimidating at first, but trust me once you get the hang of it, you’ll be able to do all sorts of awesome things like installing new software or editing files without having to click around in a bunch of different windows.

So let’s say you want to check what version of Linux you’re using (because sometimes that can come in handy). All you have to do is open up your terminal window and type “cat /etc/os-release” this will show you all sorts of juicy details about your operating system, like the name, release date, and kernel version.

Another useful command is “ls,” which stands for “list.” This lets you see what files are in a particular directory (or folder) without having to open up a bunch of different windows or tabs. For example, if you want to check out the contents of your home directory (which is where all your personal stuff lives), just type “ls ~” and hit enter this will show you everything from documents and photos to music and videos.

Now, let’s say you want to create a new file in that same directory. All you have to do is open up your terminal window again (or switch back to it if you closed it) and type “touch mynewfile” this will create a brand-spankin’ new file called “mynewfile.” You can also use the “nano” command to edit that same file, which lets you make changes without having to open up a bunch of different windows or tabs.

Of course, this is just scratching the surface there are all sorts of other cool things you can do with Linux once you get more comfortable using it (like installing new software or setting up your own web server). But for now, let’s focus on mastering these fundamentals and taking over the world one command at a time.
