I’ve seen this one recommended in the past. I think it’s great for beginners yet still full of useful information.

Linux is a tool. And I find that the best way to learn handling a new tool is making a project with it.

A book is (maybe) fine, but a project will help you use your knoweldge while you gain it.

So set up a Lemmy/Minetest/Matrix/Teamspeak server or write a bash script to change your audio output device/volume or program a simple bot in your favorite programming language or mix some music or gather a bunch of PDFs and search through them and concatenate them

And while you do that and create directories, change permissions, move files, create users or “cat” or “grep” or “sed” stuff, find out, what every single line you write in a terminal does. And instead of using a graphical program to move files, shutdown your PC or update all programs, only use the command line.

This will help you in the long run.

I think you need like a project that will give you a goal and things to look up to do specific things. What got me into Linux was running a minecraft realm, then we hit limitations on the service so opted for a server instead which lead down the road to a VPS and had me using Linux and commands

Nice to hear that you have found your way to Linux. What helped me a lot to understand Linux and the command line better was trying to install Arch, following the instructions in the wiki, failing at the first attempt and trying again and finding the error.

In addition to rhe other advice, I’d add what helped me the most: install arch from scratch.

Use an older PC you have lying around, or just a VM. Use the installation guide on the arch wiki (or a video on feetube if you prefer to listen to a human explain stuff) and just learn as you go.

There’s a book called “How Linux works” and I think you might find a lot of good info there.

And at a glance, this Bash tutorial looks pretty good: bash scripting course

https://linuxcommand.org/

The best advice… Just use Linux more… It’s the only way to get familiar with it

best way: try to use it for daily tasks. Copying and moving files? terminal, moving around? terminal, editing text? vim. Etc etc. Eventually you will learn to use it.

Also check out RobetrsElderSoftware’s “[command] is my favorite Linux command” shorts to find out new commands. Also install tldr (sudo apt install tldr on mint, sudo pacman -S tldr on Arch & derivatives) it’s very helpful when you want more (and better formatted) info than [command] --help but less than man [command]

My first recommendation is to become familiar with one flavour of Linux. Debian is a solid choice and it will give you a good understanding of how a great many derivatives operate.

The command line is a tool to get things done, it’s not an end to itself. Some things are easier to do with a GUI, many things are easier to do with the command line interface or CLI.

Many Linux tools are tiny things that take an input, process it and produce an output. You can string these commands together to achieve things that are complex with a GUI.

Manipulation of text is a big part of this. Converting things, extracting or filtering data, counting words

For example, how many times do you use the words “just” and “simply” in the articles you write?

grep -oiwE "just|simple" *.txt | sort | uniq -c

That checks all the text files in a directory for the occurrence of either word and shows you how many occurred and what capitalisation they used.

In other words, learning to use the CLI is about solving problems, one by one, until you don’t have to look things up before you understand why or how it works.

There’s someone posting a pretty well-crafted intro to Linux series here on Lemmy. Look for that and go to the linked website and dive into the parts that you find interesting. I think they post a course chapter per day in the format of (approximately) “Day 15: Topic for that day.”

I’ve skimmed some of the course material and thought it useful for beginners. I’m really happy that they keep posting each month.

• Ctrl-C will not do what you expect, use Ctrl-Shift-C, or click mouse wheel
• There are many better terminal emulators that XTerm
• If you accidentally press Ctrl-Alt-F1, you can press Alt-F7 to switch back to the graphical desktop
• There are in fact many ways to exit vi, no need to reboot your PC
• There’s no need to suffer through The True Commandline Experience For Real Fedora-Wearing Sysadmins⁽¹⁾, just install mc and get all the benefits without typing cd and ls every time you want to find a specific file

⁽¹⁾ Real Fedora-Wearing Sysadmins don’t use vi to edit files, they either write a sed script or use cat to copy the file to the terminal, then use cat again to copy the contents of the terminal back into the file by clicking the mouse wheel while typing manually the lines they need to change.

https://programming.dev/c/linuxupskillchallenge always tempts me to learn something.

I never had an IT background and also “just tried” Linux a few years ago.
Now, I’m still not an Linux expert, but relatively proficient with it.

I tried reading “How Linux works” (free e-book), but didn’t have a great time with it.

It’s just too detailed for someone who just wants to use Linux. It might be an absolutely great resource if you plan to work in IT, but other than that, just it’s too much wasted time.

What helped me a lot was to use Linux as an OS for my homeserver.

You don’t need anything fancy for it. Just use an old spare laptop or something similar you have laying around, or buy an used small form factor PC, like those Mini-PCs many businesses use. Those often cost less than 50 bucks and would otherwise land on the trash.

Then, install your server OS of choice. The most popular one is just plain ol’ Debian, and it’s what I used. It’s a great choice!

Servers run without a display or GUI (DE/ WM). You set it up once, and then connect to it remotely via SSH.
With that, you can either install a web interface like CasaOS or Cockpit, or just use the CLI for everything.

For the start, you can choose just Nextcloud AIO and call it a day. It comes with all things needed for a functioning webserver. But, things said, the learning experience ends here pretty quickly. It’s made to be easy and painless.

If you want to learn more, then consider setting up the stuff for yourself. It’s also really not hard (coming from someone who doesn’t IT stuff professionally!), but takes a bit more time, because you have a lot of choices.

For that, you might consider checking out c/Selfhosted and awesome-selfhosted on GitHub.
Theres a lot of really cool things you can discover!

The main reason I recommend that, and not just “Try LFS, Arch, Void, Gentoo, or whatever” is because I find it pretty much useless. Sure, you learn how it works, but for what price?
When you set up your own homelab, then you have actual useful things running, you also learn a lot, and maybe you can add it to your CV when applying for jobs. I for example work in the chemistry sector, where IT stuff like this is pretty useless on the first glance, but I often got invited for a job interview exactly because of that. It’s just a nice skill to have!

For checking out great CLI tools, check out the according video from TheLinuxExperiment or other YouTube/ PeerTube videos.

Try to learn the basic commands, like cd, ls or cat, then look up for more advanced/ alternative tools, like tree (instead of ls), bat (instead of cat), and so on, and then try to learn shell scripting.

I really like using fish instead of bash, because it’s a very friendly and interactive shell ;)

I hope that my comment was helpful! :)
