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.

This channel is awesome man. I’m a 33 year old math teacher who never learned this stuff in school. I’ve always been the person to ask “why” And allot of the coding stuff out there just goes into how to use the coding language without going into how it actually interacts with the hard drive and how it literally works. So this is fantastic.

[@Zodiacman16]

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.

[@mz00956]

It just bricks the OS right? So after reinstalling Linux you can use your pc again. (Without your files obviously)

[@commander3494]

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.

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.

[@m4rt_]

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.

[@4.0.4]

There is also /opt which software can use to /opt out of the correct file system structure.

[@zeckma]

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! 😆

This was actually ridiculously informative. Wow. Great video fireship. Been getting into Linux and thought I’d know most if not all but there were definitely a few I didn’t know about. Keep doing this!

[@kamrandoesstuff]

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.

[@Saturate0806]

5:55 a few comments. 1: Use "#!/usr/bin/env bash" not "#!/bin/bash". 2: if using shebang and invoking the file as a program, you need to set the executable flag "chmod +x ./file". 3: you don't need the shebang if you intent to invoke the file by specifying the shell first eg. "bash ./file" I use arch btw

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.

[@axlslak]

just wanted to point out, and am sorry for being pedantic. about the cat | sort | uniq. its ok to use cat as a learning tool. I get it. But in a memory constrained system, might want to not use cat at all. depending of what you are doing, might want to use awk. But if its a single column, can use uniq first, then sort. and not use cat at all. all of these commands can operate files. or just standard input. that's the point of pipes. but you dont need to occupy extra memory with cat with sort OR uniq can read files just as well. so instead of piping 3 commands, you just use 2. and again, based on the use case, maybe changing order could also save on memory.

[@jbird4478]

You _could_ use uniq before sort but, depending on the file, that will give you a different result, because uniq only works on _adjacent_ lines.

[@alemswazzu]

I don't think memory is a major concern in 2024.
