Probably, but see if pv is nicer for your purposes. pv (pipeviewer) will give you constant status output for data passing through it. For dd, you'd replace something like ## dd if=/dev/foo of=/dev/bar with ## dd if=/dev/foo | pv | dd of=/dev/bar There are options for pv such as naming the progress bar or telling pv the expected size (so you get a percentage complete) and so on. Might be useful to you.
