Mount a single bitlocker volume. Run it with sudo and without any arguments. If multiple bitlocker drives are connected, only the first one will be used.

mount-bitlocker.sh

#!/bin/bash
set -e
for dev in /dev/sd?1
do
	if [[ $(blkid -o value -s TYPE $dev) == "BitLocker" ]]
	then
		dev_name=$(basename $dev)
		mount_path="/media/$SUDO_USER/$dev_name"
		dislocker_path="/media/bitlocker/$dev_name"
		mkdir -p $dislocker_path
		if [ -f $dislocker_path/dislocker-file ]
		then
			echo "$dev_name is already unlocked!"
			continue
		fi
		mkdir -p $mount_path
		dislocker -V $dev -u -- $dislocker_path
		mount -o loop $dislocker_path/dislocker-file $mount_path
		read -p "Mounted! Press ENTER when you're finished to umount the drive again."
		umount $mount_path
		umount $dislocker_path
		break
	fi
