[英]reboot mail with wall message
Im searching for a solution to the following: I use Ansible to orchestrate my infrastructure and when I patch my CentOS systems I reboot after the upgrades have finished using: /sbin/shutdown -r "Ansible Linux Updates triggered reboot". 我正在寻找以下解决方案:我使用Ansible来协调我的基础结构,并在修补CentOS系统时使用以下命令完成升级:/ sbin / shutdown -r“ Ansible Linux Updates触发了重启”。
Now what I'd like to get is an email with the message when the system is rebooted. 现在,我想获得的是一封电子邮件,其中包含系统重启时的消息。
In cron you can select the @reboot flag and mail it, but how do I get this message from my shutdown command into the cron, or is there a whole other solution to my question? 在cron中,您可以选择@reboot标志并将其邮寄,但是如何从我的shutdown命令将此消息发送到cron中,或者我的问题是否还有其他解决方案?
Thank you kindly for your assistance! 谢谢您的协助!
