So this is fantastic.

[@tristanreid5770]

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.

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.

[@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! 😆

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.

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!

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.

The picture at 17. ext4 - 2:16 is a bit misleading, the Filesystem Hierarchy Standard (FHS) isn't tied to the filesystem itself (be it ext4, xfs, btrfs or zfs). As a couple other comments mentioned: RHEL/CentOS 7 was the last version using yum, since then dnf is used as a package manager. On halfway recent versions "rm -rf /" does nothing, you have to add a star symbol after the slash or explicity add "--no-preserve-root" for it to work.
