CentOS: Alert all desktop users from comand-line
command line;console;desktop environment;notifications
You can try wall.  On my KDE machine, a small panel pops up with the message sent with wall.  Of course, the message also appears in all terminals, but maybe your users do not have a terminal open.  Example:echo It is 9 o'clock and all is well. | wall
