I was afraid you meant that.  =8~)  My three scripts are executed 
interactively. To my knowledge there can be only one script in a file.  
=8~|  By defining chell functions, all three are in .bashrc.  =8~)

OK, my first stage follows.  ~/MY/ is an SD card.  This Backup is 
executed when I finish editing something or finish enough editing that 
I wouldn't want to retype it after the flash store fails.  It merely 
syncs from ~/MY/ into ~/MY0.Bak or, if executed with any parameter, to 
~/MY1.Bak.  Then it reports the size of MailMessages and the current size 
of the backup.  Subdirectories, logs, voice messages, installer archives 
and similar non-essential data are excluded.  Definitely more 
primitive than your backup.  Comments welcome of course.

The further two functions put the backup on a DVD-R.  Done once per 
week or less depending on competing "essential" work, fatigue & etc.  Can 
discuss these stages 2 and 3 later.

Thanks,                         ... Peter E.
