# Gives a dmenu prompt to mount unmounted drives.
# If they’re in /etc/fstab, they’ll be mounted automatically.
# Otherwise, you’ll be prompted to give a mountpoint from already existing directories.
# If you input a novel directory, it will prompt you to create that directory.

# Inspired from https://github.com/ihebchagra/dotfiles/blob/master/.local/bin/dmount
