How can I track the progress of dd after I've already started it?

I'm migrating my HDD to an external hard drive so that I can do a clean install of OS X Mojave.


I'm using dd if=/dev/disk02 of=/dev/disk15s2 to accomplish the task.

disk02 is the Macintosh HD (SATA-HDD), disk15s2 is the WD External HD



I didn't realize that it wouldn't show me any indication of progress (the HDD has ~750GB on it) - this is the first time I've done this through the terminal.app in recovery mode.



Is there a way for me to track the progress in another terminal window while it is in progress?


I'm on a Macbook Pro mid-2012 running El Capitan.

          Yes, from a separate terminal you can issue this command:



          kill -INFO 1234


          where you need to replace 1234 with the pid of your dd process. You can look it up with the ps command.



          Another simpler way is to request the progress information from the same terminal as dd by pressing Ctrl-T.

          • Thank you, both of those work, Ctrl-T is definitely more effective
