linux command dd [sudo] dd if=blabla of=blabla bs=1M status=progress

on mac seems status parameter can not be specified explicitly

[sudo] dd if=blabla of=blabla bs=1M this is enough

send SIGINFO signal to see how it works now

pgrep -l '^dd$'
kill -SIGINFO 8789
watch -n 10 kill -USRINFO 8789

reference show progress during dd
