Simple bash scripts to backup and restore several archlinux config files

arch-backup.sh

# Storing installed package names
echo $(pacman -Qentq) > pacman.bak
echo $(pacman -Qemtq) > yay.bak
echo $(pacman -Qdq) > pacman-optdep.bak

cp -r /etc/pacman.d/ pacman.d.bak
cp /etc/hosts hosts.bak
cp /etc/hostname hostname.bak
cp /etc/vconsole.conf vconsole.conf.bak
cp /etc/resolvconf.conf resolvconf.conf.bak
cp /etc/localtime localtime.bak

# Highly recommended to clear cache from Chromium, Discord and similar apps before this recursive copy
cp -r ~/.config config.bak

arch-restore.sh
