Ubuntu :: Crontab Job Not Executing

I am a xfce user. I have a list of wallpapers and I wanted to change them every 5 minutes Initially I was using a simple command in crontab entry to change it, Quote: */5 * * * * xfdesktop --reload it was working but it would crash xfdesktop process after few changes and the screen would be all grey. To solve this issues I wrote a simple script which would check if xfdesktop is alive and if yes it would call xfdesktop --reload else start xfdesktop I called this script idesktop & its path is ~/.bin/idesktop

[Code]....
