verbose du dd

Started a dd but wondering what the progress is? I haven’t found a way to do a verbose mode for dd, but this command seems to do the trick.

Lets start off by creating a dd of /dev/sda1

dd if=/dev/sda1 of=my-dd.img

We’ll need to find the process number of our dd which can easily be done with the following command.

ps -ef | grep dd

we’ll get something like this

root 31733 31268 54 10:44 pts/0 00:01:55 dd of my-dd.img

Now we can run our command to find the status of this dd. Open another terminal session.

kill -SIGUSR1 31733

and looking back at our dd page we should see dd dump out a status of its current progress.

dd if=/dev/sda1 of=my-dd.img
