带有通知发送的 Cron [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 是这样的:

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 并且该命令实际上每分钟执行一次，但没有弹出通知.有人能帮我理解为什么吗?

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?
