passing macro variables to shell script

[Onsite DeTeWe]

Hi Andreas

Now why didn't I think of that...  What a star you are.

Still a bit new to all this linux stuff, although a friend of mine keeps 
telling me that I have graduated beyond novice just on the basis that 
nagios is working at all ;-)

Thank you, everyone for all your help.

Kind regards

Jason

Ofcourse it is. Just pass the macros as arguments. For the
above-statement you'd want something like this;

# in misccommands.cfg:
define command{
command_name  service-notify_by_sms-spam
command_line  /path/to/thescript.sh $HOSTNAME$ $HOSTADDRESS$ \
"$SERVICEDESC$" $SERVICESTATE$ "$OUTPUT$" "$DATETIME$"
}

#!/bin/sh
# the shell-script
for num in 040404040 1414141; do
cat << END_OF_MESSAGE | /usr/local/bin/gnokii --sendsms $num
Host: $1 ($2)
Service: $3 ($4)
Output: $5
Date: $6
END_OF_MESSAGE

# other commands (like sleep) go here
done
