To view the progress of dd we can use the pv (pipeviewer) program.
apt-get install pv

I saw a usage example on other sites but they didn’t work from me
dd if=test.img | pv | of=/dev/sdx bs=4M This just returned 0B 0:00:00 [ 0B/s] [<=>

This is what worked for me (note the use of dd again after the pv pipe)
dd if=test.img | pv | dd of=/dev/sdx bs=4M
