fixing yay error:
	(yay: error while loading shared libraries: libalpm.so.12: cannot open shared object file: No such file or directory)
	$ cd /tmp && git clone 'https://aur.archlinux.org/yay.git' && cd /tmp/yay && makepkg -si && cd ~ && rm -rf /tmp/yay/

changing shell:
	(if you can't press up or down keys because shell is sh instead of bash)
	$ chsh -s /bin/bash
