To create a debian install stick, one copies the iso to the device:
cp debian-testing-amd64-DVD-1.iso /dev/sdb
per this page:
https://www.debian.org/releases/jessie/amd64/ch04s03.html.en
according to this SE question:
How to check progress of running cp?
one can monitor the progress using stat -c "%s" /dev/sdb
Despite the light flashing activity on the thmubdrive, stat is reporting 0
I tried rsync, but rsync fails, reports 'no space left on device'
dd would be a more appropriate tool for the job in this case and if you use pipe viewer you can pass the dd command through it. e.g
dd if=debian-testing-amd64-DVD-1.iso | pv | dd of=/dev/sdb
if you use the --size/-s option and specify an approx size it will also try give an approximate time.
dd if=debian-testing-amd64-DVD-1.iso | pv -s 3G | dd of=/dev/sdb
You simply can't since cp has no monitoring functionality.
The SE question you refer to relies on a filesystem which is not your case. How could any application know what represents actual data as opposed to random junk present on the drive?
