# If Linux OS, adjust the folder/directory path for your tee output destination.

tee c:/temp/MDWN-DB-last-tee.txt;
may take the following requests to a single filename of your choice
to be attached to your email to us. In this case, C:/TEMP must be write enabled.

If the tee works for you, run the requests from the MySQL Command prompt
and you will not have to use clipboard and Notepad type software.
