From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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!

If you really want the deep dive, look into LFS (Linux from scratch), besides that I've always been the learning by doing kind of guy. Got a problem? Search a solution and read up on the intricacies of the problem

[–] sorrybookbroke@sh.itjust.works 14 points 1 year ago* (last edited 1 year ago) (16 children)

I can also suggest installing gentoo if LFS is a bit much, which is understandable. It won't have as much direct information as LFS but if you look up everything you don't understand and follow all the links you'll get a fairly good concept of the thing

[–] Krafting@lemmy.world 5 points 1 year ago (1 children)

I think they should try learning the basics with an easy to use and install distro (learning cmd like cd, lsblk, ls, ln...) then if they want more try to install arch Linux using the arch-install, then installing arch linux manually, and the diving into gentoo and then into LFS if they really want the time! (Also, for gentoo and lfs i'd recommend having a really good computer to make compilation time slower!)

[–] fbsz@lemmy.ml 4 points 1 year ago (1 children)

Hey, I've tried some distros(fedora, ubuntu, vanilla...), I think it would be better If I learn. What I mean by learn is about understanding the concepts and, as I've been using fedora. I didnt really learn how cd, ls(although I use it a lot) works. So, I think learning through LFS is good and interesting. Do you think that it would be good if I learn from installing gentoo and arch, then go onto LFS

[–] Krafting@lemmy.world 5 points 1 year ago (1 children)

If you're interested, you will learn a lot of things by installing lfs, arch or gentoo, you'll just learn differents things with each distro and will learn in a different manner, all are interesting imo, but I think it's better to learn gradually than to learn from the hardest thing (lfs is the hardest in my opinion)

[–] fbsz@lemmy.ml 2 points 1 year ago

May be, I wasn't all interesting how the things work when you download it! Yeah, learning gradually will not only save time but also make the learning process enjoyable.

Hey, thanks for the great suggestion. Looked onto it and it's great to build your own linux. I think that's really the essence of linux, the freedom to build it on your own.

I've been dabbling with Linux for 30 years and it's only in the last few that it really clicked. I needed a project.

Go start a home server and give yourself projects to work on. Makes Linux very fast to pick up.

[–] PetDinosaurs@lemmy.world 5 points 1 year ago (1 children)

A simple distro, like one for a raspberry pi, is also helpful.

[–] Happenchance@lemmy.world 5 points 1 year ago

I actually would recommend learning a hypervisor.

Not first. For sure. But before you want to do anything serious.

Proxmox made learning home service hosting so much easier and faster to unfuck.

[–] Kangie@lemmy.srcfiles.zip 15 points 1 year ago (9 children)

IMO running through a Gentoo installation is a great way to learn.

The handbook is well documented and walks you through all of the steps that an installer would traditionally do.

You can do it in a VM or bare metal if you're feeling adventurous!

[–] banazir@lemmy.ml 4 points 1 year ago

Yeah, Gentoo is a good way to get your hands dirty. Reading the guide and trying to dig in deeper as to what you're doing will give you a decent understanding of Linux.

[–] 30p87@feddit.de 3 points 1 year ago

And for more in depth explanation of compilation, patches etc. consider LFS, or at least reading the 'book' on https://linuxfromscratch.org/

Even manually installing Arch is a good way to understand the parts of a Linux system, stuff like users, package management, etc. Without heating your house all summer compiling the kernel.

Heres a tl;dr of some "must learn" things in order to use GNU/Linux in an acceptable fashion;

  • Package manager (how to install, remove, clean old packages)

  • The "know-hows" (Which package goes for audio, video card, webcam, etc)

  • How to make a minimal/baremetal installation (Which is a very simple process nowadays -- it takes only one package to do this)

Thats it.

A good way is to build Linux from scratch. It gives you a totally new perspective of not just Linux but any operating system and is a lot of fun! https://www.linuxfromscratch.org/

Fun weekend project for the whole family !

[–] Sir_Simon_Spamalot@lemmy.world 10 points 1 year ago (1 children)

Just type a bunch of stuff, then play with your kids as it compiles!

[–] RandomLegend@lemmy.dbzer0.com 5 points 1 year ago

Let your kids compile the kernel! It's super easy and fun, rated for ages 2-99.

[–] AnUnusualRelic@lemmy.world 8 points 1 year ago (1 children)

What I did back in the day when I started Unix was mostly explore.

I looked at what was in /bin and read their manpages, or just browsed manpages to see what did what (your desktop manager will probably have a help browser nowadays that makes this much easier, in KDE it's the Help Center), and generally experimented with stuff.

Poking at things to see what they do is probably the best way, especially on a system that's not production. Also there will be a lot of reading involved, although it will mostly be to get a feel of things, as in the end, you'll essentially have to be proficient in finding information rather than memorising it for the most part.

And don't get too hung up on the whole distribution thing, in the end they all install the same stuff anyway.

[–] fbsz@lemmy.ml 2 points 1 year ago (1 children)

Wow, I've planned to learn linux by exploring and doing. Any suggestions on exploration?

[–] beeng@discuss.tchncs.de 3 points 1 year ago* (last edited 1 year ago) (3 children)

Create a VM on your current machine, install it, install software on it, try use it as your daily driver. Don't forget to take snapshots of your vm incase you break something.

But.. Then again, if it does break, nothing like reinstalling again to make sure you know what you're doing ;)

How linux works is a nice read, tells a bit about what's going on under the hood.

Nothing will teach you the basics of Linux better than a good ol' Arch installation.

The MANnly way is to use the man pages for things your curious on. The arch wiki is another fantastic tool

[–] Makussu@feddit.de 6 points 1 year ago (1 children)

Try setup arch or even gentoo with the help of the arch wiki or gentoo wiki

Delete a bunch of files from /bin then try to get back to a working system (hard mode)

If you want to learn the terminal there's a game called Hack Net that teaches you command line. IMO if you pick a distro like Ubuntu, Pop, Zorin or Vanilla you don't need the terminal tho

[–] cerement@slrpnk.net 4 points 1 year ago

if you really want to get into the details, there’s the Linux Upskill Challenge ( !linuxupskillchallenge@programming.dev and https://linuxupskillchallenge.org/ ) – runs through the nitty-gritty of running a Linux server – aimed at remoting in to a command line but it looks like the majority of the lessons would work just fine from a terminal or console on your own computer

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!

Think of a project you want to do, seek how to do it and do it, then break it and fix it.

[–] macallik@kbin.social 2 points 1 year ago

I took this Udemy course for ~$10. Great lecturer who is passionate about Linux and FOSS
