This video cured my Linux imposter syndrome. I recognized and understood way more than I thought I would. Another Fireship banger, for sure.
I’d just like to interject for a moment. What you’re refering 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.

Or develop an existential crisis as a developer. You never know 😂
Ive been watching almost all his vids since I stumbled upon that channel.
I not a software engineer, I never code in my life, I understand nothing. But somehow in coming back :p
In this particular case, I only came for the punchlines. About the only thing I learned from the video was that I didn't know the logos for a lot of distros.
I'm in the trades and I watch for the memes.

6:42 What a transition 🤯
What a **sponsor blocked**
This is why fireship is the best online educator / content creator, he taught everything that there is to know about linux and shell commands in just a 12 min video when others are selling month long courses.
On that chown stuff, when he said the stuff about 7s, it can be kind of cryptic where those numbers come from. The idea is that 7 in binary is 111. Those 3 ones are rwx (read/write/execute), the 1 means that they're all turned on. A 000 would be all turned off, or another example is 6, which in binary is 110, so read & write are turned on, but execute is turned off. Read-only is 4, which in binary is 100, so only the read bit is turned on.
I learned it that way so it is the default in my head... until I get to sticky bits

3:21 "open up the terminal which is a graphical user interface"
🤣
I mean, the actual terminal application is graphical, just not the actual interfacing with the underlying operating system.
Yeah, it sounds funny, but actually the terminal is a graphical user interface to the shell, providing an experience similar to using a serial terminal or the console, but in a graphical window.
Missed opportunities to talk about ttys right after
@@agh0x01 Though technically the console is also graphical in a way, just much more limited as it's restricted to outputting characters (albeit in a font of your choice, and these days usually with colour).
@@traveller23e on a modern PC using framebuffer console, yes, but on other hardware types, you might really be limited to character mode.

Really loved this one, very good recap!
I think this is your best video yet, and I've followed you for years. Very entertaining and informative. Well done.
4:10 Correction, as you can read in the title of the manpage: "touch" simply changes file timestamps. Though this has the side effect of creating an empty file if the path given isn't an existing file, so it often gets used to create new files.
MS should have aliased "New-Item" to "touch", it feels intuitive even when it's being used incorrectly.
😅😢
_Ohhhhhh_ that makes sense! I never thought to question the link between this "touch" and the "touch" in Rails.

Debian forever!!!

Bikefag kek
Debian on my servers, NixOS on my desktop; Two WILDLY different beasts, but I love them both... NixOS is not for the faint of heart, though.
heh, nice distro kiddo. I use Guix btw.
Also, neat to see you here.
Wait I didn't expect you here xD
Everytime I watch a intro/beginner's guide video for linux/bash cmds, there's something new I haven't used before
This is like everything I learned in my Linux course last semester in like 10 mins.
bro can you not make a 12 minute video that sums up a year of college. thanks
It's not fireship's fault that your professor is incompetent.
So, I take it you went to a for-profit college?
A year?! I learned to love Slackware in three months when I was in high school. Also, I’m dumb for loving Slackware.
everyone replying here is a headarse. No this video does not teach you everything a college OS class does
@@krishp1104 I think they’re being being sarcastic
for those curious about the "sudo rm -rf /" command:
- "rm" removes a file (or directory with a flag)
- "-r" is recursive, meaning if you target a folder with rm it will remove everything in its subfolders too
- "-f" is force, makes rm work without confirmation
- "/" is the target path, which is the root directory of your entire computer
- "sudo" gives you elevated permissions, lets you do things you wouldn't normally be allowed to do, like write to system folders
so "sudo rm -rf /" will remove the root directory of your computer, recursively delete everything inside it, with elevated privileges and no confirmation prompts. it basically bricks your machine because it removes important system files.
It just bricks the OS right? So after reinstalling Linux you can use your pc again. (Without your files obviously)
@@mz00956 yeah, it can't really touch your BIOS so you can still boot from other devices. But / includes every device that was mounted so you better unplug that install USB before you run it!
@@mz00956 i think in some cases system firmware can be mounted as rw causing your whole computer to get bricked
though most distros require the --no-preserve-root as a safeguard to prevent rm rf / from being used accidentally, so running it will usually not actually do anything, but if you do add the flag... expect things to break (don't do it outside a vm)
Most modern distros will not let you remove the /. To make it work, run it as: sudo rm -Rf /*
@@SteveStavropoulos --no-preserve-root too iirc
Hey jeff, thank you so much for making the courses affordable, forever grateful to you 🙏
Beautiful content! Thanks!
8:14 Correction. The "usr" directory stands for "UNIX System Resources" or "UNIX Source Repository", it's a common misconception that it means "user".
Also, the /bin and /lib directories are meant to be for binaries and libraries required for the system to boot, while the /usr counterparts like /usr/bin and /usr/lib are meant for programs that aren't that necessary that every user on the system should have access too. There is also directories in /usr/local that are usually things that are more manually installed while it still should be accessible to everyone. There is also the ~/.local directory which is meant as the same as /usr/local but for things that should only be accessible to that one user since it's in that users home directory.
There is also /opt which software can use to /opt out of the correct file system structure.
Most distros have /bin, /lib{,32,64}, and /sbin be symlinks to /usr/*. Plus most often when distros compile software, they set the prefix to /usr, and bindir is either /bin or /sbin, so installed programs get put in /usr/bin or /usr/sbin. The LSB/FHS can be picky where certain apps go, like chroot should be put in /usr/sbin instead of /usr/bin. For the regular user, though, it really doesn't matter. Does help where the binaries actually are if you're in a pinch and don't want to rely on using PATH to launch something. I manually install many things and just put em all in /usr/bin, unless the project is big and has different library versions that make removals difficult -- then I put the package in /opt. Rust is one of them, but also Java.
It’s not a misconception, ‘user’ was the original meaning. The others are very recent backronyms, and frankly quite terrible ones! 😆
Shut up nerd
This entire thing is a massive retcon. The directories actually mean "Hey Dennis we're out of space on this PDP-11 disk, mount another disk somewhere" and anything else is made up rubbish.
Learning and using nixos (linux distro) recently just blew my mind. Having an entire system configured in a git trackable file and easily revert to any state in time is just amazing.
Absolutely based and nix pilled
Welcome to the club, and good luck learning Nix
You clearly don't know what's been going on behind the scenes with NixOS.
The project being on the verge of collapse aside, it's just a gimmick, albeit an interesting one. No documentation, abhorrent language, gorillion poorly built packages, many dev issues due to symlink dredge filesystem, and is just pure trash for desktop for anything nontrivial. Interesting for servers though, for what it's worth. Will stick to Gentoo
You can even track your config file in other version control systems! Git isn’t a requirement for Nix :)
@@aarholodian can confirm as an arch user gentoo is the only other wiki I have to frequent.
The real reason to use any distro is how well it's wiki is maintained
The first person to explain Linux so well. Thank you Fireship
I don't know if I have time to learn linux right now, but your courses actually look like a great idea, because you're wonderfully enunciated for this sort of content. If I do find time, that's where I'll go.
You released this video at the perfect time for me given that I switched to Linux earlier this week lmao

Great format and content
kudos. well done cram session with highlights. got a chuckle for the Slack CD (=
I am new to Linux ,and my brain feels fried and rewired at the same time after watching this.
Theres alot in here youll rarely need to use (ie. whoami) Figuring out how to move around the files system and manage files is the only requirement to learn at the beginning (cd=change directory, ls= list files, cp = copy, mkdir= make a new directory, vi/nano = write some files, rm= remove a file, mv= move a file). Then as you find the need to do other things, you can add them to your toolbelt over time.
apropos is also very useful. And never forget man.
I felt the same too
If you rarely use linux in the server side, you can take it easy and just use GUI in general, most programmers don't even need to use linux if they have dedicated sysadmin/devops team
@@traveller23e lol so true, tho i once forgot apropos and was trying to think of apropos

Fun fact: The GNU project was born in 1983 while the Linux kernel was born in 1991, in fact GNU lacked the kernel and Hurd was created.
Hurd was the initial kernel of GNU and unlike Linux it was a microkernel, it still exists but development is at a standstill and there are a couple of older distros that use this kernel.
This. I feel bad for Stallman since Torvalds is kind of a disgusting person. I wish linux was never invented and GNU existed without it.
