Linux Basics/If you want to deal more with Linux
If you want to watch some Linux content on Youtube, I'd recommend DistroTube,Switched to Linux and ExplainingComputers. The last one it's not Linux oriented, but has some Linux content, I prefer Chris' channel.
I also prefer joining Telegram groups to get some help if you're stuck(most distros have at least English language groups and some local ones like there is an Ubuntu Hour community in Hungary which has its Telegram group), most Linuxers use this platform, although some like ArcoLinux's developer(Erik Dubois) uses Discord too.
In Hungary, members from FSF uses a matrix server (matrix.grin.hu), to communicate with each other, and there is the PenguinPit Discord server for those who use Discord a lot.
This article from itsfoss.com contains 25 free Linux books to learn more. I also prefer The Linux Command Line which contains lots of knowledge in 555 pages. However, on Wikibooks, there are some Linux books here too. Check them out, maybe those get your attention.
