How to sendmail via command line piping

view full story

http://serverfault.com – I have a cron command that runs a file and I'm trying to setup the output so it emails to me. I use this with 3rd party scripts that I don't want to modify the direct files, so I need to pipe the output instead of modifying the PHP. I'm migrating from a server that uses mail to a server that uses sendmail. I'm struggling to find out how to properly send a subject to sendmail via a command line. /usr/local/bin/php -f /path/to/file.php 2>&1 | /usr/sbin/sendmail -s "My Test Email Subject" [email protected] (HowTos)
