Lil' Linux Lesson - Sudo for beginners!

[@VeronicaExplains]

Want to help me decide the next "Lil` Linux Lesson" topic? I'll be putting a poll out to Patrons before doing the next one, so make sure to check that out- it's a great way to help support the channel. And thank you! patreon.com/veronicaexplains

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.

[@ignabelitzky]

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!

[@lawrencedoliveiro9104]

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)

[@Nikolai508]

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.

[@bennihtm]

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

[@mikehosken4328]

[@neilbrideau8520]

I've been using sudo since 1995. At this point I give it no thought. I'm only here for your impeccable dictation.

[@oceanz55]

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!

[@simonvannarath]

Oooh OmniOS! I run it as a VM/container host. You’re probably running pfexec instead of sudo?

[@JoanDoe-pq5fu]

Intro to package managers would be an apt subject for a lil` Linux lesson topic.

[@VeronicaExplains]

I see what you did there!!

[@tvsmed]

You should do much more of this. Fantastic voice and way of explaining things!

[@chischis4666]

Just recently came across your channel. Super educational and informative. Also love your humour, amazing work!

[@sherrilltechnology]

Great video Veronica!! Linux is awesome and so are you!

[@lawrencedoliveiro9104]

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.

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)

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.

[@walterwinnipeg7350]

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.

[@tvsmed]

That guitar riff at the beginning sounds really nice!

[@LadyTink]

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 :)

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.

[@emberavenge7162]

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.

[@ubuntujackson9133]

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.

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!

[@nephisto2]

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!

[@zyedkhemakhem]

[@The_Penguin_City]

[@Storm_.]

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.

[@MikeWood]

sudo apt-get more Lil' Linux Lesson. ;) If you are going to cover the sudoers file, then perhaps some sudo syntax too?

[@JarrodCoombes]

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 ).

[@mikehosken4328]

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 -

[@VeronicaExplains]

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. :)

[@kevingary7018]

I always thought sudo was some kind of martial arts until I discovered Linux.

[@treakzy_9594]

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! :)

Phil Collins likes sudo too. He just says the word.

[@pmccarthy001]

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?

[@lawrencedoliveiro9104]

That group is just one of the ways of controlling access to sudo.

[@GAVollink]

sudo is very important on macOS, too!

@@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

[@jennycotan7080]

Ah, in my first week of Linux life, while installing a dozen of softwares via apt, I learned that the "sudo" command requires your current user password once, and in a while you use it again, it won't ask you for your password again... Interesting. Just going over this famous command here.

[@aron6814]

veronica which is your Favorite Linux distro?? { of everyday use]

[@MisterConscio]

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?

[@marcos_pctech]

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.

[@mkrleza]

Full marks on Lil' format. As a single user, you don't actually need a root user, right?

[@ThisIsReMarkable]

Even so, it's still advisable to have root, and have a less privileged user. That way, you have to be intentional about changes and, if anything gets onto your system, there's less of a chance of destroying the entire install. Essentially, damage mitigation

[@VeronicaExplains]

Depends on the distro and the application, but generally I like to disable root access and just go all-in on sudo. If the installer gives me that option, I nearly always take it. :)

[@lawrencedoliveiro9104]

System admin functions require privileged access that is not needed while doing normal user tasks. It is best to keep them separated. In particular, never log into a GUI session as the root user.

[@radiicall]

doas is also pretty good for home computers but it doesnt offer the flexibility for servers like sudo

Is SUDO kinda like run as Administrator?.

[@ariel_chess]

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?

[@BradleyBrown]

My favorite sudo command is "sudo !!" as in, 'Crap, I forgot to put sudo in front of that last command.' It repeats the previous command with sudo priveleges... I really wish Windows had this. I don't know how many times I get the feedback that the terminal or PowerShell isn't running as Administrator. 🤦‍♂
