#!/usr/bin/env bash

# Instructions
# ---
# On top of a clean install of Arch Linux, for example after https://gist.github.com/lvaylet/c931e881f4038080b47646be1da6be65:
#
# 1. Download this script with:
# $ curl -Lo install_my_linux.sh -H 'Cache-Control: no-cache' https://gist.githubusercontent.com/lvaylet/5bad228cfb854756dac972d67dcfe969/raw
# or, thanks to GitHub's URL shortener:
# $ curl -Lo install_my_linux.sh -H 'Cache-Control: no-cache' https://git.io/JRsiW
#
# 2. Make the script executable by the current user with:
# $ chmod u+x install_my_linux.sh
#
# 3. Run the script with:
# $ ./install_my_linux.sh

# TODO
# [ ] Install and configure zsh, Oh-My-Zsh and Powerlevel10k (or stick with bash/zsh/fish + Startship?)
# [ ] Install Rust programs recommended by DistroTube as replacements of GNU utils (https://www.youtube.com/watch?v=dQa9mveTSV4)
