A simple AUR helper script. It moves and extracts a snapshot downloaded from the AUR to a build directory, allows you to compile it and when done moves the binary package to a bin folder and deletes the downloaded files

aurhelper.sh

#!/bin/bash

# run this by sourcing it, i.e. "source aur -x" or ". aur -r"
# you can make it easier on yourself by making a alias
# for example, alias aurhelper="source /path/to/aurhelper.sh"

src_dir="/home/user/aur_packages/src/" # change these to whatever you'd like
bin_dir="/home/user/aur_packages/bin"
