Posted to Querying the dd command over 1 year ago

You're right, thanks for reminding me about the existence of the SIGINFO signal. Indeed, some implementations of dd listen to that (non-POSIX) signal instead of USR1 in order to write the current input and output block counts to stderr. This seems to be the case for most BSD variants and Mac OS X, as you mentioned.

Thanks for the remark!
