How to send e-mail on startup on Ubuntu 16.04 LTS?

  • 772

I have tried a few things so far but with no success.

I modified crontab and and preceeded the command with @reboot mail.mailutils ...

I also created a .sh script, changed permission, added it to init.d modified configuration with sysv-rc-config --level 3 script on and added the necessary line to rc.local.

I would really appreciate if you could tell me where else to look!

I just want to send an email when I boot my Ubuntu (desktop not server) and when I turn it off.

The script that I am using is not even a script is 

mail.mailutils -s "subject" emailaddress <<< "message"
startup 14.04 mailutils

  1. First, check if you can send email. I am using mailutils to send email, the way to send email is:

        echo "system start" | mail -s "start" [email protected]

    Second, add a systemd task to listening the boot and shutdown event.

    1. create a file /etc/init.d/myemail, then add the following scripts.
    2. sudo update-rc.d myemail defaults
    3. now its done.

    4. Tips: some email provider will intercept your email, since your email account is not like a common email format.

      #! /bin/sh
### BEGIN INIT INFO
# Provides:          myemail
# Required-Start: 
# Required-Stop:
# Default-Start:     1 2 3 4 5
# Default-Stop:      0 6
# Short-Description: on boot and shutdown send a email.
# Description:
### END INIT INFO


PATH=/sbin:/usr/sbin:/bin:/usr/bin


. /lib/lsb/init-functions


case "$1" in
  start|status)
        echo "system start" | mail -s "start" [email protected]
        date +"%Y-%m-%d %H:%M:%S   --start" >> /var/log/myemail.log
        ;;
  restart|reload|force-reload)
        echo "Error: argument '$1' not supported" >&2
        exit 3
        ;;
  stop)
        echo "system poweroff" | mail -s "poweroff" [email protected]
        date +"%Y-%m-%d %H:%M:%S   --stop" >> /var/log/myemail.log
        ;;
  *)
        echo "Usage: $0 start|stop" >&2
        exit 3
        ;;
esac

return 0
