Hello Richard,
I have never done that and don't know if it's possible. Cron is
meant to run commands unattended so they are not seen.
It has been some time since I last did something of this sort, but you should set the proper DISPLAY variable in cron and authorize the cron
user to use that display.
I have never done that. It might be possible, I wouldn't know.
I think you can do it, but it sounds very fragile to me. Plus, if you don't have a working display by the time cron triggers, it all will
crash.
There is nothing fragile about cron. It just gets stuff done on schedule. There
is no way (that I know off) to see what cron is doing but it will go ahead and
do what you tell it to do, when you tell it to do it.
If invoking the scripts from a graphical interface was a must, I would forget about cron and use my desktop environment to load a while loop
that called the commands periodically.
Yes, if you want to see some kind of output cron is not the way.
Ttyl :-),
Al
