I’ve been using Linux for about 7 months now and have become a lot more comfortable using the terminal but I feel like there is more that I can learn.

Most of my work is done in a browser or DaVinci Resolve. I do try to use the terminal where possible but it’s limited due to my workflow.

Are there any interactive sites where I can practice/learn the terminal? I’m going through Linux Survival at the moment.

EDIT: I forgot to add some important details.

I don’t have a massive need for the terminal for my current workflow but I think it is important to know (looks good for any future job applications as well) and expand your knowledge on things that interest you when possible.

In the future, I hope to have a home lab/NAS running Linux. I will most likely SSH into that and I’d like to deal with any issues via the terminal.

I use Arch btw (technically EndeavourOS)

    I have never practiced using the terminal. The only way I learned was using the terminal to do my tasks and fix things when they broke.

    In the future, I hope to have a home lab/NAS running Linux

    Just start this project. That will teach you about how to use the terminal in a practical setting

    This website has a bunch of great practice “wargames”. You’ll learn a bunch about common linux commands and the different options for them. It also provides you with some great tips on what to google if you get stuck. I reccomend starting with bandit.

    In m opinion, practicing with real life problems is the best teacher. There are some ways to cut and convert videos, audio and images via terminal. Maybe there is still a way to enrich or streamline your workflow with that. Maybe a script which will prepare the folder of your next project. Also, xdotools let you automate a lot of sometimes tedious routines.

    The Linux Experiment fairly recently made a video about this: https://tilvids.com/w/w5SrXQUhk1a5iEtE9xPWgS

    If you just want the links:

    I also recommend learnlinux.tv and especially the YouTube channel

    Since you’re on Arch, the Arch Wiki is a great resource if you ever need to look something up. If you just want to improve your CLI skills and make the life in the Terminal more pleasant, I’d recommend the fish shell. (Check this out if you want a video demonstration) It has a great autocomplete feature and shows you a short description of each command, which might help you to learn more about it. It’s also very flexible and customizable. (Check out this video for some neat tricks) My last recommendation is tldr, it’s a very useful application that gives you a short summary of how to use a command. These summaries are much easier to read and understand than manpages. I assume you know about manpages, if not, that’s another recommendation.

    As many here have said, but I will emphasize: learn the Bash programming language. Linux Survival is a very good start, and you can just start experimenting right away in your own terminal on your own computer.

    To go more in depth, you can read through the manual on your computer by typing “info bash”. The Info documentation browser is a command line app. You may need to install it using your package manager (“apt-get” or “pacman” or “dnf”).

    In the “info” app, you can navigate with the arrow keys, pressing enter on hyperlinks, typing l (lowercase “L”) works like the “back” button in a web browser, typing r (lowercase “R”) works like the “forward” button. Info also lets you search the index by pressing i (lowercase “I”) then entering your search in the prompt, or search the full text by pressing s and entering your search in the prompt. And q quits back to the command line prompt. “Ctrl-Z” pauses the “Info” app and drops you back into the command line, and you can resume your “info” session using the “%” (percent sign) command.

    Another thing that can help is to learn about the GNU “Coreutils”, this is a suite of commands usually installed into /usr/bin or /bin which provides helpful command line utilities. These are commands like cat, wc, sort, cut, ls, du, cp, ln, chmod and many others. Read through the Coreutils Info manual by typing “info coreutils”.

    And I will also reiterate recommendations from others: learn how to use Vim and/or Emacs. Vim has the more difficult learning curve but is extremely useful for writing scripts. Emacs is better though because it lets you split-screen with manual pages, and copy-paste commands between Man pages, “Infodoc” documents, the shell, and/or a text file, all using only keyboard commands. I think it makes it much easier to learn since everything is integrated together. Ask the Emacs community how to get started if you are interested.

      Thank you for such a detailed response.

      I’ve tried learning Vim previously but I never really gave it as much time as I should have. I haven’t tried Emacs yet, I’ll have a look at that as well.

    Cost: $10

    One year of a small vps. Fiddle around with it, get it secure, run some services on it, flatten and reinstall through the web kvm when you fuck up.

    Look at your logs and be terrified at how many computers are just out there poking and prodding at random ips on the internet.

    Say “I’m in” and push play on squarepusher when you log in.

    I think you might like DIstroSea. If you’d like to persist your experiments, then likely learning how to emulate systems with QEMU or VirtualBox (the latter if you’d like a friendlier GUI-led experience, the former if you want to go full-CLI virtualization). QEMU is great in how lightweight and easy to create and discard self-contained VM disk images can be.

        I’m not the biggest fan of VBox either, it’s just very popular and full of sequential “wizards” to guide the user along the process of creating VMs, so it might be one way to get started. I’d much rather work with QEMU though.

          Virt-manager is a complete full UI for Qemu (and lxc and Xen) which works essentially the same way. It’s been around since 2009.

      That looks interesting. I like the idea of trying to emulate a system only using the command line - I learn a lot from hands-on projects like this

        That might be fun then.

        QEMU can be as simple as this:

        qemu-img create -f qcow2 mydisk.qcow2 20G

        Here you are first creating a disk image with the format qcow2 and maximum 20G capacity. This is a QEMU disk image format that will take up very little space and grow as you use up the VM disk.

        qemu-system-x86_64 -m 256M -cdrom alpine.iso mydisk.qcow2

        This will start a VM with 256MB of RAM, the alpine.iso image in its virtual CD/DVD slot, and the disk image you just created as a virtual drive. This will come with networking enabled by default, so you’ll have internet access from within the VM.

        It should now drop you into the Alpine installation. Alpine is very lightweight so it’s great for experimenting, but you could do virtually the exact same for most other flavors of Linux and BSD images out there.

        Once you are done installing, you can power off the VM and then start it with this:

        qemu-system-x86_64 -m 2G mydisk.qcow2

        That’s basically the same without the -cdrom argument, this time with 2GB of RAM. I find QEMU a delight to play with because it has sane defaults like that. Hope you have fun too!

    As many people have already said, just do what you need to do. That’s the best way to learn. But if you are afraid you’ll break your system with dangerous commands, use docker or a virtual machine for practice.

      This is the crux of my whole life. If I am not interested in something, my entire existence will basically refuse to soak up that knowledge or even try to empathize. It can sometimes suck. I have to walk away if people start engaging in conversations about sports.

      It got easier to start digging into CLI after realizing that would be an easy way to get the home media server up and running. And managing local game servers.

      It’s a little harder to focus on vlans and firewall rules, outside of the repercussions of not setting that up correctly.

    Most terminals start a shell as the first program, so you’re not really learning “Terminal” so much as whatever program it starts first. Bash is a pretty common shell, so you might want to search for things like “Bash examples” to get a feel for it.

    If that’s too simple, or you blast past that, then reading bash’s manual might give you some more ideas. The man command is your friend. The manuals are not necessarily quite so friendly, but they’re aimed at someone who’s already somewhat competent.

    Anyway, here’s one link from a Bash examples search I did: https://linuxsimply.com/bash-scripting-tutorial/basics/examples/

    If Bash isn’t what you have where you are, substitute its name instead. Zsh and Fish are pretty popular. There are others, but I don’t think any mainstream Linux uses them by default.

    To check what shell you’re using try an echo $0 or echo $SHELL.

    Finally, a bit of advice: Don’t go running commands you see on the Internet unless you’re sure what they’re going to do is something you have no problem with. And be careful with copy/pasting from web pages you don’t know or trust - I can’t vouch for the examples in the link I gave earlier, for example. It’s possible to make things look like a completely innocent command but when pasted does something else entirely.

    Cmdchallenge is similar to Linux survival. But is mostly command line basics like moving around directories, searching, etc. It also gives a list of solutions that people have used for each exercise, which is interesting just to see different ways of doing things.

    Try to avoid using any file manager (uninstall them all if it is difficult to avoid running them). So you will practice in using file manipulation commands.
