Bye, GNU Coreutils. Hello, Rust Coreutils.

Ubuntu 25.10 starts the preference cascade.

Ubuntu 25.10 Planea Reemplazar GNU Coreutils con Alternativas en Rust

Canonical, la empresa detrás de Ubuntu, está considerando un cambio significativo para la versión 25.10: reemplazar las GNU coreutils, herramientas esenciales de Unix implementadas en C, por uutils, una suite de utilidades escrita en Rust. Este cambio no solo implica una actualización técnica, sino también un cambio en la licencia del software, pasando de la GPLv3 a la más permisiva MIT. ¿Qué…

The chown command is a Unix utility that changes the owner of a file or directory. The -R flag stands for recursive and lets you operate on whole folders and drives.

It's pre-installed on every every Linux and Mac, but only accessible via the command line. cht.sh and the man page are your friends!

Reblog with your worst Linux mistake

[alpine-official]

"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.

Thoughts on Linux (the OS)

Misconception!

I don't want to be obnoxiously pedantic, but Linux is not an OS. It is a kernel, which is just part of an OS. (Like how Windows contains a lot more than just KERNEL32.DLL). A very, very important piece, which directly shapes the ways that all the other programs will talk to each other. Think of it like a LEGO baseplate.

Everything else is built on top of the kernel. But, a baseplate does not a city make. We need buildings! A full operating system is a combination of a kernel and kernel-level (get to talk to hardware directly) utilities for talking to hardware (drivers), and userspace (get to talk to hardware ONLY through the kernel) utilities ranging in abstraction level from stuff like window management and sound servers and system bootstrapping to app launchers and file explorers and office suites. Every "Linux OS" is a combination of that LEGO baseplate with some permutation of low and high-level userspace utilities.

Now, a lot of Linux-based OSes do end up feeling (and being) very similar to each other. Sometimes because they're directly copying each other's homework (AKA forking, it's okay in the open source world as long as you follow the terms of the licenses!) but more generally it's because there just aren't very many options for a lot of those utilities.

Want your OS to be more than just a text prompt? Your pick is between X.org (old and busted but...well, not reliable, but a very well-known devil) and Wayland (new hotness, trying its damn hardest to subsume X and not completely succeeding). Want a graphics toolkit? GTK or Qt. Want to be able to start the OS? systemd or runit. (Or maybe SysVinit if you're a real caveman true believer.) Want sound? ALSA is a given, but on top of that your options are PulseAudio, PipeWire, and JACK. Want an office suite? Libreoffice is really the only name in the game at present. Want terminal utilities? Well, they're all gonna have to conform to the POSIX spec in some capacity. GNU coreutils, busybox, toybox, all more or less the same programs from a user perspective.

Only a few ever get away from the homogeneity, like Android. But I know that you're not asking about Android. When people say "Linux OS" they're talking about the homogeneity. The OSes that use terminals. The ones that range in looks from MacOS knockoff to Windows knockoff to 'impractical spaceship console'. What do I think about them?

I like them! I have my strongly-felt political and personal opinions about which building blocks are better than others (generally I fall into the 'functionality over ideology' camp; Nvidia proprietary over Nouveau, X11 over Wayland, Systemd over runit, etc.) but I like the experience most Linux OSes will give me.

I like my system to be a little bit of a hobby, so when I finally ditched Windows for the last time I picked Arch Linux. Wouldn't recommend it to anyone who doesn't want to treat their OS as a hobby, though. There are better and easier options for 'normal users'.

I like the terminal very much. I understand it's intimidating for new users, but it really is an incredible tool for doing stuff once you're in the mindset. GUIs are great when you're inexperienced, but sometimes you just wanna tell the computer what you want with your words, right? So many Linux programs will let you talk to them in the terminal, or are terminal-only. It's very flexible.

I also really, really love the near-universal concept of a 'package manager' -- a program which automatically installs other programs for you. Coming from Windows it can feel kinda restrictive that you have to go through this singular port of entry to install anything, instead of just looking up the program and running an .msi file, but I promise that if you get used to it it's very hard to go back. Want to install discord? yay -S discord. Want to install firefox? yay -S firefox. Minecraft? yay -S minecraft-launcher. etc. etc. No more fucking around in the Add/Remove Programs menu, it's all in one place! Only very rarely will you want to install something that isn't in the package manager's repositories, and when you do you're probably already doing something that requires technical know-how.

Not a big fan of the filesystem structure. It's got a lot of history. 1970s mainframe computer operation procedure history. Not relevant to desktop users, or even modern mainframe users. The folks over at freedesktop.org have tried their best to get at least the user's home directory cleaned up but...well, there's a lot of historical inertia at play. It's not a popular movement right now but I've been very interested in watching some people try to crack that nut.

Aaaaaand I think those are all the opinions I can share without losing everyone in the weeds. Hope it was worth reading!

Dear distro blogs,

MacOS is different from Linux mainly because it has a completely separate kernel. K? Whether or not the fundamentals of the OS are BASED OFF some obscure nonsense called Unux is irrelevant.

Sincerely, a MacOS user

The code for MacOS isnt based off of unix. It IS Unix. Specifically, its a mixture of the XNU kernel and a lot of code from FreeBSD, Which is a direct evolution of UNIX. So the way MacOS works is that the main OS is developed by apple, under the name Darwin. Darwin is constructed of 3 main components: The closed source drivers, the Closed Source GUI components, and the Open source Darwin bit, which encompasses literally everything else that computer needs to run. Darwin is a lil frankenstein made up of the XNU kernel and I/O kit, The networking stack and File system of FreeBSD, and some code by apple to make it co.patible with their custom ARM silicon.

Linux is also based off of the UNIX Kernel. It relies on the GNU coreutils to provide a way for the user to interface with the system, to state it simply.

So at the end of the day, your technically right. They aren't the same thing. But ignoring the fundamental design and history of the computers which run and control your daily life as simply "irrelevant" I believe is an extremely concerningly ignorant and frankly close-minded stance to take.

And also your just mad we put linux on the new macbooks lol eat shit anon trying to get me to monologue as an attempt for engagement.

girl are you copy_debug_sparse_string(COPY_DEBUG_EXTERNAL) within copy.c written by Jim Meyering for the GNU coreutils?

cause I've returned, and girl, I'm "SEEK_HOLE"

is this anything?

[bugged-ubuntu]

Hmm, I'm not going to be continuing to use Ubuntu with the release of 25.04, and won't adopt the LTS version next year. I should have done this a while ago honestly, but have put it off, but the switch from GNU Coreutils to uutils isn't what I'm after.

[debian-official]

i have to come clean. i dont even know what finger does

[liquidcrystalsky]

i think i hate windows so much that, as long as i'm not gaming, i'd literally rather use MacOS.

It's POSIX compliant, has a really well made package manager, brew, has very similar if not the same coreutils as linux, ZSH OUT OF THE BOX??? (most linux distros dont even do this) really good software support with most productivity apps providing native macos versions shit they recently added linux container support and that looks good.

i'll still never use it but like windows is just stupid to me soooo bad.

[linux-opinions]

GNU sucks, the coreutils suck, glibc sucks, GCC half sucks, emacs sucks, I hate GNU

this is who you're being mean to. if you even care.
