Sending RMAN Output Simultaneously to the Terminal and a Log File

If you specify the LOG option at the command line, then RMAN displays command input but does not display the RMAN output. The easiest way to send RMAN output both to a log file and to standard output is to use the UNIX tee command or its equivalent on another operating system. For example:

% rman | tee rman.log
RMAN>

In this way, both input and output are visible within the RMAN command-line interface.
