In case of reinstall, this script puts all of my dotfiles where they should be, sets up mpd and gives me the option of installing all of my previous packages from the official repos and from the AUR (requires my pkgdump script)

make.sh

#!/usr/bin/env bash

dir=~/.dotfiles # dotfiles directory
olddir=~/.dotfiles_old # old dotfiles backup directory
files="zshrc vimrc tmux.conf vimperatorrc" # list of files/folders to symlink in homedir


# create dotfiles_old in homedir
echo -n "Creating $olddir for backup of any existing dotfiles in ~ ..."
mkdir -p $olddir
echo "done"

# change to the dotfiles directory
echo -n "Changing to the $dir directory ..."
cd $dir
echo "done"

# move any existing dotfiles in homedir to dotfiles_old directory, then create symlinks from the homedir to any files in the ~/dotfiles directory specified in $files
for file in $files; do
    echo "Moving any existing dotfiles from ~ to $olddir"
    mv ~/.$file ~/.dotfiles_old/
    echo "Creating symlink to $file in home directory."
    ln -s $dir/$file ~/.$file
done
#Extra stuff
echo "Setting up mpd for user $(whoami)"
mkdir -p ~/.config/mpd/playlists
touch ~/.config/mpd/{database,log,pid,state,sticker,sql}
printf "db_file            \"~/.config/mpd/database\"\nlog_file           \"~/.config/mpd/log\"\n\nmusic_directory    \"~/Music\"\nplaylist_directory \"~/.config/mpd/playlists\"\npid_file           \"~/.config/mpd/pid\"\nstate_file         \"~/.config/mpd/state\"\nsticker_file       \"~/.config/mpd/sticker.sql\"" > ~/.config/mpd/mpd.conf
