Thanks for this, I've just been taking time to fine-tune it, and I'll
put the complete script at the end for further comments.

This is my 'notify-send' script 
=======================================================
#!/bin/bash -e

####################################################
# Variables
LOGFILE="/home/boudiccas/logs/obnam.txt"
LOGGING2="/home/boudiccas/logs/du.txt"
####################################################
# Log all stdout+stderr 
exec > >(tee -a /home/boudiccas/logs/obnam.txt) 2>&1

notify-send "Starting main backup..."

obnam backup

if [ "$?" -ne 0 ]; then
  notify-send "Unable to finish main backup."
  exit 1
else
  notify-send "Finished main backup."
  
  du -sh /media/boudiccas/backup/obnam-home
    
echo 'Sending Backup report : Backup of obnam-home completed', $(date /
-R) 'logged to' $LOGFILE 
echo '####################################'

fi
===============================================
which gives this as its output -
===============================================
Subject: Cron <address@hidden>
DISPLAY=:0 /home/boudiccas/bin/notify-send      #backup /home 
Date:Wed, 18 Sep 2013 14:12:20 +0100

Backed up 12985 files (of 159530 found), uploaded 182.7 MiB in 10m44s /
at 290.6 KiB/s average speed
517G    /media/boudiccas/backup/obnam-home
===============================================

For some reason its not processing the two "echo" lines, and I cant see
why. I've tried various things to get them to work but without success. 
Any ideas why please?

Thanks
Sharon.
