dd is one of those indispensable Unix / Linux utilities whether its cloning or wiping a drive or simply creating a bootable flash drive from an image file. The problem is operations like wiping a drive with the output from /dev/zero can take an extremely long time especially on larger hard drives. In situations like this it can be handy or somewhat soothing for the impatient to know how far through the requested action the process is.
Luckily its pretty simple to find out, simply open a new tab and execute:
pgrep -l ‘^dd$’
