One quote that I always remember: "Linux is a file based operating system but Windows is an API based operating system." That helped me to understand the overall structure of Linux as I deep dive operating systems more and more overtime.
Great video as always!
Can you kindly elaborate on this? It piqued my curiosity...
@@baka_geddy Basically the philosophy of Unix and systems derived from it is that everything should be represented as a file you can directly access, instead of an API. Of course there are better explanations.
linux is a kernel
you meant GUI?
@@baka_geddy for example. we often see &> /dev/null, which means redirect msg to null. null is a file to eliminate data. also, all the devices are treated as files. you can read from them use >,
After using Linux for more than 10 years, now I am watching Linux in 100 Seconds....😁
How many times have you installed windows on someone elses device?
@@showercat3208 Being the family's tech support person is a huge burden.
Did you learn anything new? 😏
I have used Linux for almost 25 years, and I watched it as well. Had to see what was in it.
It’s more than 100 seconds
Speaking of distros, today is Arch Linux’s 20th birthday!

“A computer is like air conditioning - it becomes useless when you open Windows.”
- Linus Torvalds.
A wise man once said
You dropped this 👑
Quote of the year lol
why?
Our king linus torvalds
Windows is better
Note: „cd ..“ doesn‘t necessarily bring you to the root of the filesystem but it goes one layer up. In this example we were in „/root“, with „cd ..“ it brings you to the root of the filesystem. „cd /„ brings you always to the root of the filesystem
Yes, that was very poor of him to describe it that way.
@@rasulali1435 agreed
I think he meant that from “/root”, all you need to do is to “cd ..” to go to the root of the filesystem for this specific machine. I agree that it could’ve been a bit better explained tho.
This was a comedy video.
I think he worded it that way so he could mention the words "root of the filesystem", and taking into account he only has 100 seconds he might have needed to cut words.
Linux is one of the most important skills you can learn as a developer, and tech person in general.
Nice, I wish it was included in computer science in my university
This is 100% true, because if you don't know Linux, you'll tend to reinvent the wheel all the time in your current programming language
This is absolutely true. No need to master it, but learn enough to get by.
Linux isn't a "skill", mate. It's just a really good OS that everyone should use. Gentoo is a skill, because setting it up is very hard. Linux Mint and Arch (with GUI installer) is already user friendly for tech normies.
@@jimbo-dev wait what! University did not teach that??
Just a few things to speed up your Linux usage. You don’t have to put the ~ in front of cd to go to the home directory. If you just type cd then it automatically takes you home. Also you don’t need to touch a file name to create it and then edit it. You can just use vi(or text editor of choice) and if it doesn’t already exist it will create it.
touch is just better to get used to as some files require different software to edit them, so touch is a universal way to make a file
File creation isn't even the design intent for touch, we're technically misusing it. But that's beside the point.
So is cat lmao, it stands for concatenate, but the shell commands are bloat af so whatever
@@lordvalen8133 well, the man page says it is a use case of the touch command:
Update the access and modification times of each FILE to the
current time.
A FILE argument that does not exist is created empty, unless -c
or -h is supplied.
Could also just > from echo and avoid vi altogether...
would love to see Xorg in 100 seconds
That would be amazing

Yes 😱
As a frontend dev that uses a windows machine, it feels like it's about time to give linux a try given that I'm already using bash in my terminal.
So, did you change OS to linux or stayed on Windows?
@@NAL2790 He stayed on Windows.
I'm thoroughly impressed - thought this was just click-bait but actually quite a good overview well done and enjoyed the animations
excellent work! love your ability to break these complex subjects down into a short and concise video
This is great! Please make a Linux beyond 100 seconds, it would be awesome! Thank you very much for all the hard work you put in 🙏🤩
It's already beyond 100 seconds. The video is about 162 seconds long. :)
@@linuxgeek64 is this a meme on this channel or why is literally every 100 Seconds video around 160 seconds long? 😂
How it will be awesome, Linux has its plus and minus that you already know.
Hell yeah, this freaking 100 seconds have been the most informative 100 seconds of my life. Made all the sense to my 3 years of experience using linux as an os.
Using Ubuntu since 5 years now, today learned the full form of apt thanks to you !
Used this video a few minutes before a computer science test in school and made me get through it amazing bro
Waoo. I just commented 100 seconds of linux in your last video. And here it comes. Thankyou so much 😇
Finally someone who actually says what the commands are short for
I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
“I use Linux as my operating system,” I state proudly to the unkempt, bearded man. He swivels around in his desk chair with a devilish gleam in his eyes, ready to mansplain with extreme precision. “Actually”, he says with a grin, “Linux is just the kernel. You use GNU+Linux!' I don't miss a beat and reply with a smirk, ”I use Alpine, a distro that doesn't include the GNU Coreutils, or any other GNU code. It's Linux, but it's not GNU+Linux.“
The smile quickly drops from the man's face. His body begins convulsing and he foams at the mouth and drops to the floor with a sickly thud. As he writhes around he screams ”I-IT WAS COMPILED WITH GCC! THAT MEANS IT'S STILL GNU!“ Coolly, I reply ”If windows were compiled with GCC, would that make it GNU?“ I interrupt his response with ”-and work is being made on the kernel to make it more compiler-agnostic. Even if you were correct, you won't be for long."
With a sickly wheeze, the last of the man's life is ejected from his body. He lies on the floor, cold and limp. I've womansplained him to death.
@@cgarzs Hah! What mortal fools. I sit on my thrown being fed potato chips like grapes. Linux, windows, mac, all childs play. All pathetic. Little trivial matters that seem so insignificant, for I have ascended.

You're so good at explaining things in 100seconds
I started from the first video to this video with no skip.
your videos is amazing
The package manager is honestly my favorite part. I can get everything I need quite easily, and it’s automatically put in the right spot, even when downloading through GUI. Although I use Windows for gaming because of compatibility, I prefer Linux because it has so many features that you can use and you can specify it to exactly fit your needs and preferences.
i'd love to see videos on vi/vim and emacs. They seem incredibly daunting for beginners but can be incredible powerhouses. Also specific intros to certain popular desktop environments/distributions could be an interesting topic
A quick search finds Vim in 100 seconds: m.czcams.com/video/-txKSRn0qeA/video.html
vim in 100 seconds czcams.com/video/-txKSRn0qeA/video.html
he already made a Vim in 100 seconds + deeper view
There are lots of channels showing distros, but I think doing a miniseries of distros in 100 seconds would be fun and useful for beginners.
Has someone coded a decent text editor for emacs yet?
Your explanation makes everything seems easier. Glad to subscribe for yoi😉
That was a fair bit of info imparted in return for 100seconds of my time. Thanks!
Love this kind of content!
Keep up the good work and let’s never forget “Free as in free speech”
Linux is, and will be, the best system for me. From coding, to video editing, to even gaming, I love that it's getting so much better than back in the day when I couldn't even get drivers for my graphics card, or where there were errors just trying to install. Ubuntu, Arch, doesn't matter. We are all one when it comes to Linux, even though it doesn't seem like it sometimes. Love the video!
I only said Ubuntu and Arch because those two are the ones I use most often so I had those off the top of my head lmao
@@elijahcruz8895 if you didn't say "for me", I and lots of other people will hell bend on proving you wrong.
@@yokowasis That is true. Don't get me wrong, I'd also love a Mac, and sometimes have to use Windows, but personally I'd rather use Linux versus anything else.
what video editing software do you use?
What specific programs do you like on linux for programming that are not available on windows?
I do appreciate how casually you mention nano and emacs in one sentence.
Ah I love these videos man. Thanks for making such high quality stuff.
The command "cd .." does NOT go to the root folder. It goes one folder up the current directory. So if you were in /home/user/pictures and did "cd .." you would now be in /home/user. To go to the current user's folder from within any folder do "cd ~". To go to the root folder from within any folder do "cd /".
Neat overview! (Although, logging in as root isn’t really good for security. But it works for a demonstration.)
lol
Yup, made a server a few weeks ago and I got a few thousand/dozen thousand requests to ssh with root, admin, test, test1, etc... I highly suggest disabling remote root login immediately and setting up a firewall. Use good passwords and good usernames as well
@@vercolit with SSH, definity consider using key based authentication.
@@vercolit definetely go for public + privatekey if you have ssh enabled and your system somewhere remotely close to the internet.
@@vercolit Disabling root login completely would nuke your system to the point it's unusable. If you want to publically test a server use AWS with a pre-configured Ubuntu AMI, you can set the Inbound Traffic in your SecGroup to ONLY come from your home public IP or a static address etc. Takes away the need for ufw etc completely.
amazing wrap-up with the history command :D
This was really well put together.
I've used only Linux for work, home and play for decades now. Unbeatable for development.
0:53 Also worth mentioning filesystems, network protocol stacks, and security management, as additional important parts of the kernel.
it probably wouldn't be 100 seconds
Extremity helpful, quick and informative! Thank you!
Taking a college course in Linux right now, having this foundation of basic commands is super useful since this is the most confusing language I've learned so far
Ayy, I'm glad to hear you use/recommend Linux. I definitely believe that more people should get into it. I set up and taught my mom to use Elementary OS and she rarely has any problems.
if more program/game developers decide to join and make their products compatible and easy to use without being a programmer then more people will use it
@@yface8347 yup having to use chmod and remember codes is so stupid over a simple gui like windows. Those things and the like need to be way simpler
@@matthewstandridge225 Some distros are starting to move towards direction for non-developers or power users, yes.
@@matthewstandridge225 You don't ever have to do that in the real world, just use a File Manager, like you do in Windows. Literally almost nothing in modern Linux distros requires a basic user to ever touch the command line.
@@matthewstandridge225 you really don't need to do that as a casual user, trust me
Note regarding sudo, it's substitute user do, not super user do. You can sudo or su(substitute user) into more than just root.
While it IS true that you can run commands as any other user with “sudo” and not just root, it still stands for “superuser do”-what you’re saying is a false etymology. The “su” command will be familiar to most old-school Unix users, and it means “superuser”.
The functionality part is true, but sudo officially stands for “superuser do”. It’s a common false misconception that it means “substitute user do”
The history command is awesome, never thought of it
Thanks alot. I just installed ubuntu as a virtual machine to aid me in learning linux. I really didn't understand commands like grep but with this short video, I now understand how it works. If you can make a full course on fireship, I would happily subscribe. Thanks a lot for your videos Jeff
The touch command was created to change the last modified date to the current date on an existing file. If that file doesn't exist it is created and then the time is set.
Why are these videos so good 😭😭??
and BTW `cd ..` is not to go to the root of filesystem but to go to the parent directory
Great video as always :)
Additional note: linux is a kernel, not an OS. I do understand though that people call linux an OS and refer to its distros.. but still wanted to correct it :) great and informative video!
Exactly my thoughts, This video actually confused me a little more because I was trying to understand the difference between Linux & GNU/Linux
Nice overview! Nowadays it's not necessary to know much terminal magic going into Linux -- you can get away with never opening a terminal if you want! but knowing some commands is always useful to get the most out of your machine (including you too, windows users!)
Its funny, I'm a vim obsessed, terminal user, but when I work in windows, I don't know how to use the windows powershell/command prompt all.
Tbf I only keep a windows partition for gaming.
I mostly agree, except that whenever you try to look up how to do something in Ubuntu/Debian/etc., people are more likely to explain how to do it with terminal commands rather than the GUI.
Agreed, but I have so much fun playing around with the terminal lol
I installed Linux with no plans to use the terminal unless I absolutely had to, turned out for some things I prefer it, oddly enough some Windows exclusive stuff is even easier to install on Linux, especially when there are side dependencies and the terminal just tells me what I'm missing
"never opening a terminal"
Blasphemy!
Thank you for covering Linux in 100 seconds and I'd love more videos about Linux, maybe showcasing a little of the desktop environment(s) so people can see how usable it is.
Your content is always fire ❤

Reason is he is using Linux on windows via WSL

I wish i could just move to linux. Its snappier than W11, and as a programmer i would love it. But it has some problems that keep me from changing:
1. Gaming.
I game a lot. Sadly, i dont play games from 1994 without anticheat that can be perfectly run with Wine or proton. I play multiplayer shooters like Valorant or Rainbow Six, and league of legends. Games you cant play on linux.
2. Windows magic ⊞ Win + V
The windows "magic" clipboard history (the one that you access with Win + V) is a tool that i use A LOT. And there arent any linux versions that are able to achieve the same result. Windows V opens where your writing cursor is, you can navigate it with the arrow keys, holds text, images, etx perfectly visible.
3. My graphics card is from nvidia.
Theres nothing more to say about that
1 and 3 sadly cant be fixed, but if someone finds a good ⊞ Win + V (see, i used Windows V to paste that unicode character, instead of searching it again) replacement it would mean a lot.
Well the third option isn't that bad tho. I use NVIDIA drivers daily without many problems on Linux.
Just make sure your distro support DKMS and you are good to go!
Dual boot windows w pop os (pop os has an installation option that will install nvidia drivers for u)
Guys you answered the only problem that wasnt really a problem. What about the clipboard
@Quique1222 Good point!
KDE has a clipboard history (just like Windows).
GNOME... Well, you have to download an extension or a different program that handles this (they exist, I just don't remember the name)
Anticipating games with AC... use Windows, yeah :(
Edit: Valorant! Not even a VM will help you.
Brother you unbelievable love your 100 seconds
You are so worth man im french but i love your videos !!!!!!!! So much knowledge in 2minuts incredible pro
1:39 you don't need to use "cd ~" to get back home, just "cd" is enough i believe.
Didn't we have it's lore before

Linux based systems are neat. Took me a bit to learn to use the terminal but well worth as a developer and as someone who values my privacy.
I do have to run a Windows virtual machine to play some games with, but Linux's Hypervisor (KVM) as well as qemu make it easy to pass my graphics card to it and it runs like native.
Bruv just use proton/steam. No need for VM
@@mohos_a doesnt work nearly as well as the vm. proton has way too many issues for me

Laravel in 100 seconds next please! I feel like it’s a technology / community many more people should be aware of
As I just got my Linux Essentials certificate, I can say this video would have saved me hours of studying!
You're not wrong but I feel that this doesn't really show Linux. It shows basic terminal usage, but today Linux is so much more. Would love another or extended version which also talks about the general usage with a DM and stuff. Cuz many people think that Linux is just that, a weird hacking thing where you type commands into the command line
What else can you show in 100 seconds
More like Linux in 50 seconds and then the bash shell in another 50 ;)
Great stuff!
i'm a Linux user i love using Linux with bsp window manager it's lightweight and easy to configure and use micro instead of vim and nano as text editor and tilix terminal emulator
There are some misleading things in this video though.
1) Linux is not an operating system. Linux is a kernel. GNU/Linux is an operating system because of the GNU part which is separate from the Linux Kernel. Some Linux based operating systems are Debian, Arch and Fedora.
2) "cd .." doesn't go to the root of the filesystem, it goes one level up. In this video it just so happened to take you to the root of the filesystem because you were just 1 level down (from /root to /). If you want to go the root of the filesystem regardless of where you are, use "cd /" instead.
3) I know that this is a 100 seconds video so I won't deduct any points from my imaginary scoring system, but apt-get will only work on Debian based distributions. Each flavor of a linux distro has its own package manager such as apt for Debian, pacman for Arch, etc. So when you install a linux-based OS, also check which package manager it comes with so that you don't get confused with why a certain package manager doesn't work for you.
Alpine Linux ain't GNU 😁
nice, I live Linux and hope you do more videos in it. thanks for this one
I'm a linux/MacOS user for almost 5 years, and now here I am. Watching 100 seconds of llinux.
Linux is not an operating system. It's a kernel that was developed by Linus Torvalds. GNU is the operating system created by Richard stallman that runs on top of the linux kernel hence the name GNU/Linux...
I was looking for such comment
You literally just described my 14 week university course on Linux in 100 seconds. Imagine if colleges presented information like these videos. Great work.
That must be one shitty university. And there's incorrect information in this video: Linux is not an operating system by itself, it's a kernel. Although we use the term Linux to describe the family of operating systems which use the Linux kernel. "cd .." changes the working directory to the one that's higher in the hierarchy, not always the root directory. ls shows all non-hidden files in the current working directory, not just subdirectories. sudo isn't a part of every distro. The GNU project only provides most of the basic command line tools, not desktop environments, etc.
Also, one of the most important commands/utilities for any newbie is not even mentioned in the video - man.
@@Regexion I was being hyperbolic. Obviously there is more information covered - but a good chunk was represented in the video.
@@mDevinm The video covers a fair bit, but at the same time it covers nothing because it can't go into any depth due to its length. It's great for people that want to be entertained by random info, but for educational purposes it's terrible. If colleges presented information like this, then students would be even more useless than they already are. People love to leave comments like "I learned more in this video than in college". Maybe if those people actually paid attention during classes, they would learn. Not to mention the fact that they will forget most of what they learned from such videos the next day.
@@Regexion Dude, it’s 100 seconds. Of course it has to be surface level…

Sorry, but it's GNU/LINUX. Linus Torvalds made only the Kernel.

Later standards meaning e.g. LSB
I've been daily-driving Manjaro for about 8 months now, but I still have to dual boot into Windows 10 occasionally. Despite having used Windows for the entirety of my life up to this point, I now find Windows incredibly irritating and difficult to work with. We've all been marinated by Microsoft to be familiar to the proprietary pile of crap that is Windows, and as we all know, familiarity is both a blessing and a curse.
How new is your system(supports hardware virtualization), and how much RAM do you have? If you have 16GB+(maybe less because of how lite Linux is) and support for hardware virtualization is enabled, you can run Windows in a virtual machine, install the Redhat Virtio drivers, and boom. Near native performance.
@@theinquisitor18 I plan on doing that in the future since dual boot is indeed inconvenient. But currently I already have all my files and software set up on Windows so it's simply too much of a hassle to move. Maybe I'll do it when the next pandemic lockdown hits.
