RE: Cron Job - GUI Application

["Alok K. Dhir" <adhir@symplicity.com>]

Why did you put "sh" in there?  Per the error message, 'sh' can not
execute the xcalc binary.

Further, aa.bb.cc.dd needs to be replaced by the ip address of your X
display server (or 127.0.0.1 if local).  I.e.

*/10 * * * * root /usrX11R6/bin/xcalc -display 127.0.0.1:0
