This is a script I did in my free time as a way to learn a more about making bash scripts, it was pretty fun to do :)
To run the script you need to install git on the archiso
pacman -Sy git
After that, just clone the repo and make it executable
git clone https://github.com/iraposeiro39/arch-quick-setup.git
cd arch-quick-setup-main
chmod +x arch-quick-setup.sh
Then execute it and thanks for using it :)
./arch-quick-setup.sh
If your network uses a proxy you need to export http_proxy and https_proxy
export http_proxy='http://127.0.0.1:1234'
export https_proxy='https://127.0.0.1:1234'
and you need to give git a proxy before using it
git config --global http.proxy http://127.0.0.1:1234
