G'day
@lekkerlinux and welcome to linux.org
Start a Thread in General LInux if you want more Specifics -
https://www.linux.org/forums/general-linux.143/ or maybe in Arch might be better
https://www.linux.org/forums/arch-and-derivatives.161/
... so that we don't "hijack"
@Xzoma 's welcome
But briefly - Arch have "Pacman Rosetta" -
https://wiki.archlinux.org/index.php/Pacman/Rosetta
... which I find good as I move around the Families.
Anything in Rosetta applies to Manjaro as well. In many Linux, you can accomplish things just with the GUI (windows-like point and click), but command line experience is very helpful, and can be more versatile.
