My colleague told demo the zenity for his shell script with interactive GUI. Wow, that's impress me. Few years ago, if I want a shell script with GUI, I usually write dtksh script, but it's quite hard to use. But zenity seems much easier than dtksh.
And OpenSolaris doesnot have dtksh in default, that means, even I want to do a hard work, but I still cannot use it.
So I decided to study it, and start the epidose with zenity.
Wish this helps.
