man dd ‘status=LEVEL’ Transfer information is normally output to stderr upon receipt of the ‘INFO’ signal or when ‘dd’ exits. Specifying LEVEL will adjust the amount of information printed, with the last LEVEL specified taking precedence.
‘none’ Do not print any informational or warning messages to stderr. Error messages are output as normal. ‘noxfer’ Do not print the final transfer rate and volume statistics that normally make up the last status line. $ dd if=/dev/null 0+0 records in 0+0 records out 0 bytes copied, 0.00415153 s, 0.0 kB/s $ dd if=/dev/null status=noxfer 0+0 records in 0+0 records out $ dd if=/dev/null status=none $ I like the final one, except I don't want to miss warnings. So please add a ‘quiet' Do not print any informational messages to stderr. Warning and error messages are output as normal.
