Badge +1


This is my first topic, please keep nice with me ;-)

i have create a service wich use a script python. i build an url to return on the field “Extended status information”

for example :



But when i receive the notification by mail, the character “&” (Ampersand or esperluette in french) is missing

This is my command of notification by email :

/usr/bin/printf "%b" "$SERVICEOUTPUT$\n\$LONGSERVICEOUTPUT$\nNotes : $SERVICENOTES$\nLien d'aide de resolution : $SERVICENOTESURL$\n\n\nDate/Time: $DATE$/$TIME$\nService: $SERVICEDESC$\nHote : $HOSTALIAS$\nStatut : $SERVICESTATE$\n\n" | @MAILER@ -r -s "Supervision ALICE - $SERVICEDESC$" $CONTACTEMAIL$


Have you got an idea to keep the “&” on my url please ?


Thanks a lot.
