add cron job to foreground

rated 0 times [ 3] [ 0] / answers: 1 / hits: 2307 / 2 Years ago, thu, may 12, 2022, 3:55:09

I am trying to run a program that pops up a graphical notice to me. As a simple example, I have my cron settings as

@hourly xlogo

and if I launch xlogo from an interactive command, it works fine. However, when run by cron, the xlogo window never launches. How can I get cron to let xlogo launch a window, or is it just fundamentally not designed to do that?

It is totally possible to do this with crontab.

You need to tell the script which screen you want xlogo to run on.

Try changing the line to this:

@hourly /usr/bin/env DISPLAY=:0.0 /usr/bin/xlogo

to tell crontab what display you want it to use. Depending on the program you might need to add in more enviornment variables as well.
