Mounting disk images

You probably know how to mount an image of a file system through a loopback device:

mount -o loop fs.img /mnt

But what if you have a disk image with partitions? Simple: Add the offset of the partition as a parameter:

mount -o loop,offset=1048576 disk.img /mnt

But how to get this offset? You can use fdisk -l/sfdisk -l to get the start of the partition and convert it from sectors to bytes by multiplying with 512 or use this small script:

Run it on a disk image and it will print the mount commands for all available partitions.
