Recently, I’ve been using linux(tried multiple distros). I’m curious about how linux works, it’s architecture! Is there a book, guide, video, etc to learn about linux? By using linux, I get to know something. It would be better If I know how linux works!
I would start with YT channels like Learn Linux TV, Distro Tube, and Lawrence Systems, they have a bunch of great Linux content especially for beginners and intermediate learners.
Freecodecamp.org YT channel has a free 6 hour intro to Linux course that is very good. you might want to check that out as well.
For using a distro hands on while learning, any basic distro will do. You might want to check out Arco Linux first though. It’s an Arch based distro that is specifically meant for Beginner and Intermediate Linux users to dig in and learn the nuts and bolts of the Linux Operating System. They have their own resources and the majority of things you learn for one distro will carry over to any other.
If you’re looking for a formal certification, Comp TIA has a Linux+ certification and there is also a Linux cert called the LPIC-1, both of these are beginner level certs. If you study on your own the earlier resources I listed, you could probably pass those certs pretty easily, but they are only useful if you are trying to get a formal job as a Linux Sys admin, and even then, most jobs want higher level certs than those.
Still, if getting a formal piece of paper is motivating for you, they might be worth looking into.
The most important thing though is to just pick a distro, open up the terminal, open up a YT vid and start pecking away. If you have a spare old computer you don’t need, wipe the drive and install a distro on it. That compy becomes your dedicated learning machine for the next year. Make sure it’s one you can destroy because…trust me…you will destroy your installation at least a few times if you’re really trying to learn.
If you have no spare computer, fire up a distro as a VM in something like Virtual Box. This can be useful because you can save old VM states to recover if you blow something up, although learning to recover from disaster without having to literally start from scratch is a valuable skill in and of itself.
Good luck and have fun! I got started with Linux about 4 years ago and it’s been an amazing ride so far!
