cron job not working for xwindow

问题

I have following line in crontab */1 * * * * xeyes

it does not show any xwindow but on the contrary */1 * * * * touch somefile.txt works fine

Tried to search on google but didnt get any specific answers!!

回答1:

You have to tell cron where to find the X server if the command you run uses it.

So use: env DISPLAY=:0.0 xeyes or export DISPLAY=:0.0; xeyes.

Some cron implementations (Debian, Ubuntu, ...) allows to set enviroment simply in cron file.

DISPLAY=:0.0
# m h  dom mon dow   command
*/1 * * * * xeyes
