Thank you. Took a couple of tries to get the syntax correct but I
ended up with this:

if [ `ls *.jpg 2>/dev/null|wc -l` -gt 0 ]

then for i in *.jpg; do mmv "$i" `date +%s`-$a.jpg; a=a+1; done

fi

Works beautifully. (I ripped out the directory names to prevent
wrapping as that stuff is all buried deep in /home/username/.....)
