notify by email when command is run

tonj · 08-12-2012, 04:32 PM

I'm running centos5.8 server and I want to be notified my email when a certain command is run,
eg: # /etc/init.d/<program-name> start
Can this be done? I've set two cron jobs to 1)start and 2)stop a program but I'd like email notification when it happens. I searched on google but couldn't find anything specific to this. Thanks for any pointers.

thanks but I don't use mailx, my server uses sendmail.

mailx is the client tool; sendmail is an mta; Linux uses both, just like most other *nix.

I'm surprised to discover mailx is already installed, I didn't even know it was there. It's not a very friendly app. I've been reading the manual and so far cannot see how to start it, or how to connect it to a command phrase. Are you sure mailx can do what I need?

Just follow the examples in my link

I tested 'echo "This is the body."| mailx -s "mailx Test1" me@mysite.com' in a console and that worked but I don't see an example of how mailx will send an email when a command like "/etc/init.d/<program-name> start" is run.

Sysv init scripts display status on stdout so your cron jobs should be mailing it already unless you unset the MAILTO variable. Check your mailbox?

thanks unSpawn, I created the cron jobs in the webmin gui, not in a console and webmin did not display a mailto option. I don't know whereaabouts in the console I would specify the mailto option...

MAILTO is a default, see 'man 5 crontab'.
