Hi! Thank you for this tip.

But i don't comprehend how type thid command:

"at> EOT"

EOT stand for "End Of Text" ?

Thanks.

Ctrl D

Use Control-D, the at command then echos back <EOT>. Control-D is used to signal end-of-file. As I recall, EOT means End-Of-Tape. I've also seen it used for End-Of-Transmission.

Caught that, eh? :)

I was hoping phonetically at least your first name sounded like "Christopher" -- but I likely butchered that too. :)

Thanks for the tip, I'm thrilled it works with the at scheduler, even though it is a GUI app. Often cron/at don't interact well with Xwindows, but in this case it worked great.

I was surprised it worked that way too.
But, if you do want to use "at" with a GUI app you just need to set the DISPLAY first.

If you do this it will run xterm in the background:

at 12:55
at> xterm

But, if you do this the windows will appear to the user:

at 12:55
at> DISPLAY=:0.0 xterm
