That is useful information, but I solved the problem another way. I
have long used gxmessage to pop up a list of Unicode key values for
IPA characters that I need. So just now I added the following line to
the end of my script:

gxmessage -name Home/jjj_backup -geometry 1300x200 -center -fg black
-font "Junicode 22" $TS Home Backup Exit Status $?, Zero=Success

I tested it and it is working perfectly. When I get up i the morning
that message will be in the center of my desktop with an OK button to
dismiss it. To hell with mail. This is even easier. Problem solved.

Now to get to work on a script to back up /. The fun never ends. :)

Much thanks to all for all the suggestions.
