Running crontab cmd for user without knowing Env DISPLAY

frenchn00b · 07-10-2007, 05:08 PM

Hello,

I set up my crontab for user with Kcron.
That's nice program but I need to setup some X things: xmms in the morning.

So to do so, we need this command line:

Code:

env DISPLAY=:4. xmms -p

with this great Importance : env DISPLAY=:4.

Because of the quantity of users using the machine during the day, the env Display is variable from 0 up to 6. The pc is in my room, to wake me up with xmms the morning. So, is there a way to run the crontab user with this variable DISPLAY.

Thanks

It might work like that: DISPLAY=:4 xmms -p
However it may fail if the display is not :4 at this time but :0 or :1... or if you are not allowed (see xhost).

hence if I understand well, I should make a perl code with:

Code:

ps -aux | grep "xinit"

checking where is the DISPLAY then exec cmd this X apps.

hmm
