Cron与notify-send [英] Cron with notify-send

问题描述

我需要显示来自cron作业的通知。我的crontab是：

I need to show a notification from a cron job. My crontab is something like:

$ crontab -l
# m h  dom mon dow   command
  * *   *   *   *    Display=:0.0 /usr/bin/notify-send Hey "How are you"

我检查了 / var / log / syslog ，该命令实际上是每分钟执行一次，但它不弹出通知。
任何人都能帮助我理解为什么？

I checked /var/log/syslog and the command is actually executed every minute but it doesn't pop up the notification. Can anybody help me understand why?

推荐答案

我找到了答案：

$ crontab -l
# m h  dom mon dow   command
  * *   *   *   *    export DISPLAY=:0.0 && export XAUTHORITY=/home/ravi/.Xauthority && sudo -u ravi /usr/bin/notify-send Hey "How are you"

谢谢，
Ravi

Thanks, Ravi
