How do you monitor progress of dd command?

by Radosław Śmigielski

Why?

Who doesn’t know the dd command?

And how many times have you dd some ISO image or other large files and you were sitting, looking at terminal and asking questions, how long is it going to take? how much data has been copied so far?

It was very frustrated.

And now, the old dark days are behaind, with the new dd option: status=progress.

How?

And here is how to use it:

dd status=progress if=Fedora-Workstation-netinst-x86_64-29-1.2.iso of=/dev/sdb

Below you can see how the progress is shown:

$ dd status=progress if=Fedora-Workstation-netinst-x86_64-29-1.2.iso of=/dev/sdb
3202617856 bytes (3.2 GB, 3.0 GiB) copied, 7 s, 458 MB/s

Enjoy!
