To create an image from a drive
sudo dd iflag=fullblock if=/dev/sdx of=/path/to/new.iso status=progress
Alternatively, to create a USB drive from an image
sudo dd iflag=fullblock if=/path/to/iso of=/dev/sdx status=progress
In Linux it can be as simple as (pick one):
cat /dev/sdx >/path/to/image
pv /dev/sdx >/path/to/image
cp /dev/sdx /path/to/image
or (not as simple, but quite common example):
dd if=/dev/sdx of=/path/to/image bs=8M
cat /path/to/image >/dev/sdy
pv /path/to/image >/dev/sdy
cp /path/to/image /dev/sdy
dd if=/path/to/image of=/dev/sdy bs=8M
