A Note About GUI Tools and Cronjob
You need to request local display/input service using export DISPLAY=[user’s machine]:0 command if you are using cronjob to call your scripts. For example, call /home/vivek/scripts/monitor.stock.sh as follows which uses zenity tool:
@hourly DISPLAY=:0.0 /home/vivek/scripts/monitor.stock.sh
