#Try "status=none" $ dd if=boot1h of="/dev/r$temp1" status=none
From dd (coreutils) 8.21 docs:
'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. 'progress' Print the transfer rate and volume statistics on stderr, when processing each input block. Statistics are output on a single line at most once every second, but updates can be delayed when waiting on I/O.
