Your post is kind of confusing, maybe a language barrier. Can you give a bit more detail and possibly some examples of what you are trying to do so we can give you a better answer?

In your crontab, just add, for example:

Code:

@reboot echo "$(hostname)" | /usr/bin/mail -s "Server up" user@domin.com

macemoneta's post is more than likely your solution but I wanted to clarify what you were trying to accomplish before I gave you some code. Is that what you were looking for?

Run the command 'crontab -e' as any user. Paste in the line above, and save the file.

can you please check the below command ...

# crontab -e

* * * * * /sbin/reboot echo "$(hostname)" | /usr/bin/mail -s "Server up" deepak_message@domin.com

is the above correct?

No, the line must start with "@reboot" not "* * * * * /sbin/reboot". Check 'man crontab' for the syntax.

Thanks macemoneta, this problem solved out.

A big thanks to you :-)

I'm surprised you were able to access your server after adding this to your crontab

Code:

* * * * * /sbin/reboot echo "$(hostname)" | /usr/bin/mail -s "Server up" deepak_message@domin.com

Wouldn't that make the server reboot as soon as it started up?

No Kustom42, I made the crontab which was provided by macemoneta.
