I have a huge disk image backed up using dd. I need to restore the disk image but dd is very silent.
How can I monitor its progress?
Execute the following command in the second terminal:
where nnn is the PID of the running dd process.
dd will print its I/O statistics to the standard error.
You can make the transfer happen faster by increasing the default block size for the transfer:
Remember to only use this with both drives unmounted, or you could end up with a broken filesystem on the destination drive if either drive is written to during the transfer.
