From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

rm -rf /
make computer faster
(͠≖ ͜ʖ͠≖)
Wait I did this to my main drive everything went black is this suposed to happen? will it start working again?
in case you aren't joking, rm -rf / (albiet with a warning now) will delete allll the files on your system, so everything going black is the expected result.
rm is remove, the - is to indicate that you want to pass arguments, and r&f are recursive (delete stuff in the folders in this folder) and force (don't ask for confirmation). The slash afterwards designates the root folder, the folder with everything in it.
So "rm -rf /" means "remove, recursively and forcefully, everything in the / directory"
@Blisterexe @pineapple , after making a snapshot of VM. Sometimes, I do it just for fun and then roll back to the snapshot. Fun times.
- You can always use
man commandand just read through it. If you want less text, usecurl cheat.sh/command(learn how to use aliases) or the toolstldrandcheat - Install the fish shell, it makes using the terminal waaay easier, out of the box.
- Install Alpaca flatpak, and use tinyllama or bigger LLM models. Tinyllama is already very sufficient at explaining linux commands and more, and runs fine on my reasonably powerful and modern laptop. Other models may be slow as fuck.
- Use the terminal only. Log out, Ctrl+Alt+F2 and login, then use some tools.
$pwd
cd
echo
ls
cat
nano
less
more
chmod
chown
#your package manager
lsblk
dd #be careful!
udisksctl
lsusb
lspci
curl
wget
...
Note: use the man for these tools and often multiple tools do the same thing
- There is this online terminal game/quiz but I cant find its name.

Not a good idea if the goal is to learn more about Linux. Fish is not compatible to and is different to Bash in some ways, that it would be hard once not using Fish. Also getting help or sharing scripts with others will be problematic, when having a problem and researching it. For someone coming in to Linux and wanting to learn about it, I highly recommend to learn about Bash first and use it at least for months before even thinking about a custom shell. I used Fish too (and I miss some features), so its not like I wouldn't know what it is.

Alpaca is nice. GPT4All is also another one (and one that I prefer). Either way, both are good. But again like previous point, I do not recommend to install and use Ai modesl (LLMs) to learn about Linux and to get used to it. Especially the smaller models often hallucinate and lie with false claims. If you don't know it better and are currently learning, this could be a problem. I highly discourage from installing and learning with an Ai model alongside when you are new to a topic like Linux. Its also not like there wouldn't be enough good material out there anyway.
