<html><body>Hi, I need to escape the "$OUTPUT$" as one of my checks returns a "\" ( c:\ - total: 2.00 Gb - used: 2.00 Gb (100%) - free 0.00 Gb (0%) ) and this causes printf to print up to the "\" and then stop. Anyone know how I can escape the output of the variable? Regards Rabie define command{ command_name notify-by-email command_line /usr/bin/printf "%b" " ***** Nagios *****\n\nDate/Time: $DATETIME$\n\nNotification Type: $NOTIFICATIONTYPE$\nService: $SERVICEDESC$\nHost: $HOSTNAME$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\nAdditional Info:\n\n$OUTPUT$" | /bin/mail -s "*$NOTIFICATIONTYPE$ alert* - $HOSTNAME$/$SERVICEDESC$ is $SERVICESTATE$" $CONTACTEMAIL$ }</body></html>
