[PLUG] SOLVED Make cron send an e-mail upon completion

[Tomas Kuchta]

The topic to research would be X11 authorization and MIT cookies.

It will require commands to run on both sides of the command line: a) your
desktop will need to authorize the connection (every time you start
desktop) b) Cron using that authorization to display the window.

The easiest to work around is probably for Cron to write a message to a
file and some forever running desktop script checking that file and open
the dialog.

Another alternative would be to use system messaging infrastructure in
Gnome/KDE.

One could also send a message to all user's consoles by ancient command
wall.

Hope that helps,
Tomas
