How to create and mount an SD-Card image with dd

create-and-mount-sdcard-image.sh

#!/bin/bash
# 07.09.2018
# Can be used a script or just as cli-oneliner

# First declare some variables
SDCARD=/path/to/sd-card
#[Example: SDCARD=/dev/mmcblk0]

IMG=/path/to/your/image
#[Example: IMG=/home/user1/my-sdcard.img]

MTP=/path/to/your/mountpoint
#[Example: MTP=/media/mountpoint]
#[Hint: Needs to be there already]

## Now the script/oneliner itself
# Create the complete image with all partitions
[sudo] dd if=${SDCARD} of=${IMG}

# Show the details of the partitions
[sudo] parted ${IMG} unit s print

# Calulate the offset for the loop mount
# Use Start Value, here as example was/is (8192s) * 512

# Mount the partition as loop device
[sudo] mount -o loop,offset=4194304 ${IMG} ${MTP}

# Go to the mount partition
[sudo] cd ${MTP}
