The following script may be useful to you, as a cron'able screen-shooter, but more, I hope it is useful to show you a bit of what is possible in a bash script. It doesn't work with multi-head, that I'm aware of, nor does it shoot all desktops, just the active one. Have an idea for an improvement? Reply directly to me, or open a thread on CLUE-tech.
I cron mine like this:
*/3 * * * * /home/dlwillson/bin/takescrotscreenshot.sh >> scrot.log 2>&1
# David L. Willson, DLWillson at TheGeek.NU, 720-333-LANS
echo -n "$(date --utc): "
# find /home/dlwillson/scrotscreenshots -name "200*_1440x900_scrot.png" -size 17k -delete
if [ ! -d $HOME/scrotscreenshots/$today ]; then
mkdir -p $HOME/scrotscreenshots/$today
DISPLAY=:0 scrot && echo "Yay!" || echo "Bummer..."
