[opensuse] BASH: zenity/xdialog - how to check for active X session within the script?
Bash gurus, How do I check for an active display in a bash script before calling zenity or the like to request input or provide graphical output? Do I just use the DISPLAY variable? Is there something better for a test. I want some type of test I can use like: if 'TheXTest'; then zenity blahblah else echo "blahblah" fi Any favorites? -- David C. Rankin, J.D.,P.E.

All the actions of X-aware programs are directed at the display specified by the DISPLAY environment variable (at least by default), so that seems like a fine means of doing the same in your own scripts.
