How do I send email on shutdown or reboot

Hi,
I am attempting to send an email on system shutdown and start up. Right now I have a cron entry that utilizes the @reboot option. This fulfills one of my needs - getting the email on start up. How would I go about getting the system to send out an email at the other end of the process? Namely, I want an email as the system is shutting down. Theoretically, this means I should receive two emails every time the system starts (once because I shut it down or rebooted it, and once because it came back up).
Thank you

Thank you. That looks very useful. I believe I can modify that to send out the email I'm looking for.

As a follow up - in addition to the link posted above with very detailed directions, I also found the tutorial below. The link above showed up to set up the shutdown side of this project and a little extra searching showed how to do the start up (actually, I learned about the @reboot cron ability too)
To see others, run
. Spiffy little entries there. Would have been very nice to have a @shutdown option. Alas...- man 5 cron
Send email on shutdown and restart (Linux)
Anyway, thanks again for pointing me to the thread above atreyu. It was very useful in showing me what I needed and crafting the correct Google search to get the rest of what I needed.0 -
You can simply put a small script that takes the time, and send you an Email with either 'boot' or 'shutdown'.
Put it in the relevant rc's, and that's it.
For example, a simple 'boot' script can be:
Plain, simple. Leave the hassle for other folks.- #!/bin/bash
- mail -s "boot at `date`" you@yourdomain.com
Good luck!
