I don't happen to think that "tee" is the right tool here. The standard way to do this and record the error messages is with redirection. In standard linux the screen output is from the stdout device and the error message is printed to the stderr device with a standard screen setup both stdout and stderr are the screen, but when you are recording data to a log file for historical needs, you have to redirect stderr to stdout so that the tee command can actually see it. add a 2>&1 to the cp command at the end before the pipe, and tee will get the errors as well. BTW this is generically true for all POSIX compatible screen based tools.
