simple exfat mounting script with some error checking

mount_exfat.sh

#!/bin/bash
# I had this on an ubuntu box which had a USB hard drive for some basic server backups.
# this could be easily modified for other mounting types.

# REQUIREMENTS:
#   install exfat compatability
#   find the uuid of your drive (I used "ls -l /dev/disk/by-uuid" then "smartctl -i /dev/PATH_HERE" to determine which drive I was wanting

uuid="5566-77FF"; # the uuid can sometimes be longer.
mnt_path="/mount/exfat"; # mnt_path can be just about any empty folder you'd like. And it must be empty to work.
if [ ! -d $mnt_path ]; then
	mkdir -p $mnt_path;
fi

bogus="../../"; # the $path later on will have this, and we don't want it, so we'll strip it :)
drive_lookup=`ls -l /dev/disk/by-uuid | grep $uuid | awk '{ print $9 }'`;
if [ "$drive_lookup" ]; then
	path=`ls -l /dev/disk/by-uuid | grep $uuid | awk '{ print $11 }'`;
	path=${path#$bogus};
	echo "drive has uuid:$drive_lookup and is locted in $path";
	if grep -qs "/dev/$path" /proc/mounts; then
		echo "It's already mounted.";
	else
		if [ "$(ls -A $mnt_path)" ]; then
			echo 'path "'.$mnt_path.'" is not empty! Unable to mount drive';
			exit 1;
		fi
		echo "It's not mounted. Mounting drive now...";
		mount -t exfat /dev/$path $mnt_path;
		echo "But it should be now!";
	fi
else
	echo "drive not found";
fi
