Show dd ‘s progress on OSX
Posted in Uncategorized by Julian Kessel - Feb 06, 2011
Simply using kill -USR1 or -USR2 on dd's process id while copying bytes around doesn't work on OSX. You have to use -SIGINFO or -s SIGINFO to achieve that result. Unfortunately trying the first two signals kills the process completely so you have to start from the beginning.
