Monitoring dd with a progress bar

   Posted by: Dante    in General

When using the linux utility dd, there is no visual output of the progress, how long it is going to take, or anything else. Easy to solve with the use of pv:

% pv /dev/sda | dd of=/dev/sdb bs=100M

that’ll display the amount of data transferred, the elapsed time, the throughput speed, a nice progress bar, and the ETA. For devices that do not have a fixed size, let’s say, /dev/zero, there’ll be only a throughput display.
