partx

Parse a partition table and tell the kernel about it. More information: https://man7.org/linux/man-pages/man8/partx.8.html.

List the partitions on a block device or disk image:

sudo partx --list {{path/to/device_or_disk_image}}

Add all the paritions found in a given block device to the kernel:

sudo partx --add --verbose {{path/to/device_or_disk_image}}

Delete all the partitions found from the kernel (does not alter partitions on disk):

sudo partx --delete {{path/to/device_or_disk_image}}
