Arch Linux

I use Arch Linux (or the spinoff ARM version) on practically all my machines. 
 Download 
 You can download Arch here 
 Basic commands and usage 
 Before going through the install guide you really should know these. 
 Lower/upper case is important in linux. 
 You can use arrow keys to navigate through your previous commands. 
 CTRL+ALT+F1-F12 - key combination for switching between terminals 
 cd DIRECTORY - for example cd /home/baf/Downloads - chooses directory 
 nano FILE - edit a text file 
 CTRL + C - break from a command, for example a ping 
 lsblk - lists all your drives and their partitions. 
 elinks - tool you can use to view webpages from the CLI 
 irssi - IRC in the CLI in case you get lost, #archlinux on Libera should help you out if you ask nicely. 
 Installing GPU proprietary drivers 
 Nvidia 
 sudo nano /etc/pacman.conf - uncomment [multilib] and the line below it. This is required for 32bit applications. 
 sudo pacman -Syu - synchronize the repository databases and update the system's packages 
 sudo pacman -S nvidia nvidia-libgl lib32-nvidia-libgl nvidia-settings 
 reboot 
 AMD 
 Do not use Catalyst. If you think you have to, rather get another GPU. 
 Table of hardware with needed drivers is here . 
 Installing packages from AUR 
 You can download user created PKGBUILDs from the AUR. 
 Package managers 
 Pacman 
 Usage: tldr pacman + the rest of this page: 
 -S has a useful --ignore packagename flag, which lets you ignore a broken package when doing a full update for example. Use multiple times when you want to avoid installing more packages.
There's also a --noconfirm flag, which ignores confirmation of actions. 
 pacman -Qm - List packages installed locally.(that includes AUR) 
 You can get to the package cache via this command cd /var/cache/pacman/pkg/ and then use pacman -U packagename to downgrade/reinstall a package.
