I saw on the right side of the screen that you are teaching yourself machine language. Good for you. My first machine language programming experience was on a Univac mainframe back in 1974. Most fun I've ever had on a computer to this day.
A little tip that i didn't know a few months ago... If you type a command like "cd /etc/sudoers.d/" and press enter but you forgot about sudo... You can type "sudo !!" press enter and !! replace the last typed command... hope it helps someone!
There are quite a few other history substitutions, e.g. “!!” to substitute the last command “!«n»” to substitute command number «n» from your history “!«prefix»” to substitute the last command beginning with “«prefix»” “!?«substr»?” to substitute the last command containing “«substr»”.
The Lil' Linux Lesson is a great format! I would definitely watch more videos like these. That being said, the in-depth, longer videos/reviews are dope too (I use Arch btw)
Great as ever Veronica! Thank you for this! I use Omni-OS as a file server (with Napp-it) and a lot of the commands are very similar with Linux... As I fumble through using it, lessons like this are very useful! :) See you in the next one!

Thanks for a very well-explained video! I've just added myself to your subscriber list. And, I really like that T-shirt! Took me about 30 seconds to "get" the colour list reference.
I swear, so often, when I first started my linux journey, I would run across a topic that was part of some community debate. Like Sudo vs Su, and I would not know it was an update, and I would just hear someones aggressive opinion about sudo, and how bad it is. So while using ubuntu, I would feel like a inferior user. But now in the last years, I've heard more of the debate, and now I feel like the whole "debates" that occur in linux can be an issue for new users. It's hard to know who to listen to. SO far, your channel has been often helpful, and thank you for that :)
On Debian you gotta install it yourself I've found, also on Debian running "su" doesn't set your path right, so you can't run usermod. You have to enter "su -" instead and then you can run usermod as root. I'm not sure if this would be a lil lesson, and more of a longer one, but what about a video on apt and dpkg. And how to fix issues like "broken dependencies" and things like that. How to force specific versions of programs or how to package and install a program compiled from source into a .deb file potentially using checkinstall.
Thank you Veronica for making such awesome nerdy content. I was just using GNU Screen and was seeing a lack of good explanations of what a tty is etc. So I thought I would just suggest it. No matter what, keep making great content and thank you!
Thank you! I designed it myself! :) It's for sale on the website if you'd like one- all proceeds help support the channel! vkc.sh/product-tag/t568b-cheat-sheet/
I am new to Linux and have watched dozens of tutorials. I would love to see "LLL" on the most popular terminal commands. Your explanations are well done and more understandable to the noobs (me). Thanks for the content.
3:13 The key difference between “su” and “sudo”, as far as I’m concerned, is that “su” prompts for the root password, while “sudo” prompts for _your_ password. “su” lets you become any user for which you know the password, not just root. It also allows the root user to become any user without knowing their password. “sudo” gives you more fine-grained control over what users are allowed to do. Many admins prefer it because it doesn’t require the root user to have a valid password. Linux _faux pas_ I see too often: people using sudo to run su. Tisk.
just watched all your videos, got myself an old sever and some switches so I was going to try to build a sever for a home network. Your videos are will done and informative, this should be easier as I started using Linux when windows stopped support for XP. Because I have real hardware it should be more like real world experience, except for the internet as the best I can get right now is 15MB per second, there is also still a dial up that I can use. As far as the terminal I started with dos and win 3.1 and wrote subroutines in basic. your videos will be a great help to get started.
Great and powerful concept. Well done. Next commands to contemplate: cron/crontab/etc and its "newer" incarnations. OR, the at/batch system. OR, even better: how to use man pages. "man crontab" v. "man 5 crontab"
I recently discovered your channel and I’m loving it I do have a question tho, could you make a video on how to make a Linux installation media with personalized packages? Starting to like Linux, jeje

Tip: In a lot of cases i needed to edit some file with neovim, but when i use sudo all my config is gone ( same for all other programs), so, with sudo -E you will have sudo privileges but it will use your local config! it's genius!
Hello, I'm new here, that's pretty cool!, I'm from Uruguay and in school and high school everyone was getting computers with Gnu/linux installed already, it what was called "plan ceibal" I remember changing mine to windows Xp just to be able to play some video games that ran only on windows, or else you needed to know how to use wine. Always loved to mess around with the different distros, this was 10+ years ago so I don't remember exactly all of them, they where customized by the organization that gave away those laptops. Now I use windows in my personal and work environment (I'm an analyst) But I'm looking for a distro to change to, Linux is fun :) thank you for your videos!
Great video! Unrelated note, but I think that using doas for most end users is better, a majority of users who aren't power users should use doas as you only rarely need the terminal to install your occasional app, and to update your system for simple stuff like that I consider doas better.

Hey Veronica! Beautiful content! I'm a seasoned programmer (15+ years of experience) and I have reasonable understanding on using command line for day to day navigation and js/npm cli commands, and other tools that are useful to my workflow. However, I never had any core Linux foundation. If I were to study that in a somewhat structured manner what should I be looking for? Is that a topic for one of those Lil Linux lessons? Cheers!
I installed debian and accidentally made my primary user not root by providing a root password in the installer (I thought I had to repeat the password of my account). Now i have a root and a primary user. I'm so confused I edited that file to get sudo permissions. So what's the point on having that root user now?

You know I always loved sudo, then I started playing around with Unix systems that I needed to install and configure sudo... Enter visudo!!! Damn, have to learn vi all over again just to configure sudo lol.
hey can you publish the outro song somewhere? it sounds so catchy and i really like it but haven't found it on your about tab nor if i searched for "littlest punk" on your chanel. cool videos and website you got! :)
Thanks for the compliment! Patrons got a link when it first published, otherwise I'm hoping to put out the channel songs on Bandcamp sometime this year.
Hello greetings. . Thanks for your input and tutorials. The the video. Which I think is the last you did of Linux Mint 21 installed on a MacBook. I asked you a question. Please. If you can answer.
What kinds of things can you do as root that you might not be able to do simply as a member of the sudo group? Is there anything? Or, can members of the sudo group generally do everything root can do?
I enjoy your videos on the shell and it’s commands. For sudo in my Debian servers sudo is disabled. I don’t see the need for anyone else to run as root. I get that some off shoots of Debian don’t add a root user and therefore everything must be configured by sudo. It comes down to personal preference at the end of the day but I use su -
If you know what you're doing with a root user and are the only user on the machine, I think that's just fine! I figure the audience for "let's learn X" is one that is new- new users are less likely to know that stuff. Plus, in corporate systems, there's typically a group of users with assorted extra privileges, and sudo makes that pretty easy- I figure those wanting to learn it have an interest in working with it professionally at some point. :)
@@VeronicaExplains I understand... I only know that is a powerful tool... maybe grep suits better but in the end is up to you to decide... there are awesome commands out there
I like to use "sudoedit" instead of "sudo vim", cause than it will use the user's .vimrc and not root's vimrc. Could you make a video about "doas" and compare it with sudo?
You should do a video on the sudoedit command, which is a much better and secure way to edit files as root. You probably should also make a point to mention that editing the sudoer files should be done via the visudo command and not your text editor of choice. visudo is designed to help make sure you don't do something wrong and basically remove all root level privileges from everyone, including the root account (don't ask me how I know this, that was a very bad day for me, and I'd rather not talk about it :D ).
Off the topic here Veronica, but have you every played the windows 95 game called The Neverhood?? It is a claymation style game and it is old and incredible. Also, have you every messed with SDR radio for linux??
4:46 "Which command would you like to see a lesson on in future videos" That question does not make much sense to ask, because I think there are a lot of people that does not even know which commands exist. So any commands would be good.
Noob question: How would I go about it if I want to force (joke) my gf to use Linux on her machine, say I install Debian. But we would love it for her hands of fire to avoid downloading a softonic (real story). I know this is much harder on Linux than on Windows so "default stuff" should be ok. But any other vulnerability... Should I create the first user (mine) as root and then create a new user for her without the privileges from inside the OS through the GUI or does that not work as well as editing the files from the terminal? Secondary noob question: Let's say she IS using her newly created unprivileged user - *could* she (or someone else being malicious) use "sudo" in terminal anyway? Or how does it actually work? I understand it as follows: when you install the OS and create your first user with privileges, it doesn't mean you are always root, but it means you _could_ turn into root user - this is why you _could_ use sudo which sounds like it's faster/safer. But another profile without the privileges cannot use sudo (I assume?) and they would see something like "stop, go ask for permission". I'm sure this is wrong lol, but it makes the most sense to me otherwise if someone with no privileges could also use sudo it kinda defeats the purpose.

I like this short form. Great for filling an idle 5 minutes.
I saw on the right side of the screen that you are teaching yourself machine language. Good for you. My first machine language programming experience was on a Univac mainframe back in 1974. Most fun I've ever had on a computer to this day.
As always writing a comment to support the channel
A little tip that i didn't know a few months ago...
If you type a command like "cd /etc/sudoers.d/" and press enter but you forgot about sudo...
You can type "sudo !!" press enter and !! replace the last typed command... hope it helps someone!
There are quite a few other history substitutions, e.g.
“!!” to substitute the last command
“!«n»” to substitute command number «n» from your history
“!«prefix»” to substitute the last command beginning with “«prefix»”
“!?«substr»?” to substitute the last command containing “«substr»”.
0:37 The high quality graphics are what makes the concepts this channel presents understandable
The Lil' Linux Lesson is a great format!
I would definitely watch more videos like these.

Great as ever Veronica! Thank you for this! I use Omni-OS as a file server (with Napp-it) and a lot of the commands are very similar with Linux... As I fumble through using it, lessons like this are very useful! :) See you in the next one!
Oooh OmniOS! I run it as a VM/container host. You’re probably running pfexec instead of sudo?
A small and great pill of knowledge! If I may add a sugestion (as a non-patreon), SSH is a very important program for most system management, and we can use it to play remotely with a raspberry pi (which is another interesting piece to learn with in itself)
Just recently came across your channel. Super educational and informative. Also love your humour, amazing work!
Brilliant. As a beginner/returner to Linux, I'm looking forward to many more Lil' Linux lessons on the terminal, VIM, good housekeeping, and useful shortcuts.

You should do much more of this. Fantastic voice and way of explaining things!
I've been using sudo since 1995. At this point I give it no thought. I'm only here for your impeccable dictation.
I swear, so often, when I first started my linux journey, I would run across a topic that was part of some community debate.
Like Sudo vs Su, and I would not know it was an update, and I would just hear someones aggressive opinion about sudo, and how bad it is.

If you don't set a root password during the install, it does configure sudo for you afaik

I never bothered with awk. I found Perl did everything awk could do and more, and do it just as concisely.
I like to use "sudoedit" instead of "sudo vim", cause than it will use the user's .vimrc and not root's vimrc. Could you make a video about "doas" and compare it with sudo?
I always thought sudo was some kind of martial arts until I discovered Linux.
sudo is very important on macOS, too!
Try "doas", which is an alternative for sudo, originally written for OpenBSD.
When are are doing grep?
You should do a video on the sudoedit command, which is a much better and secure way to edit files as root.

doas is also pretty good for home computers but it doesnt offer the flexibility for servers like sudo
Why sometimes the group is called "wheel"? It is very strange.
