xterm trivia
Thanks Livin Free...
Here's another one... Why is it that I always get the error message "Error: Can't open display:" in my mail whenever I execute or try to call an xterm command using cron to activate the command. What did I miss? Thanks in advance UNIX gurus... |

This indicates that cron does not have permission to access your X display. Maybe if you set the DISPLAY variable explicitly from cron? I'm not sure why you would need to run an X term from cron anyway...X apps are inherently interactive, they are not really designed to be run non-interactively from cron.

I think PxT is correct in saying that the DISPLAY variable is not set. You can set the $DISPLAY in cron, or in your srcipt / application.
If you just want some quick, simple notification, you could pop up an xterm on, say, $DISPLAY=":0", with a few lines of code: Code:
#!/bin/sh
DISPLAY=":0"
Pay_Attention () {
echo "It is time for you to pay attention!"
echo "Press {Enter} when you are done..."
read _dummy_response
case $_dummy_response in
*) exit 0 ;;
esac
}
xterm -e Pay_Attention
exit
 Either way - the xterm will close when someone presses the enter key... added code tags for readability --oombera Last edited by oombera; 02-18-2004 at 08:26 AM. |
