I know I need to get [a lot] better at bash scripting, but I'm trying to learn 
how to go from green level just up a notch, first. :P I'm using rsync to backup 















































































































































































































































































































































external HDDs to another HDD, and writing results info to a backup_info.txt 
file after rsync runs.

The first iteration just wrote 'successfully completed' blah blah blah - but I 
wanted to add in checking the rsync error codes and write either 'success' or 
'this was the error code' and here's what I came up with in my first attempt at 















































































































































































































































































































































checking exit codes. Do things l00k right?

#Backup 3 external HDDs to 16TB Drive
retVal=$?
rsync -av --delete /mnt/Beers4TB/ /mnt/datastore/PBS_backup/Beers4TB
if [ retVal -ne 0 ]; then
    echo "There was an rsync error backing up Beers4TB:" >> ~/backup_info.txt
    echo $retVal >> ~/backup_info.txt
