help with special character in check command

[Rob Brown]

Since I did not receive any feedback on this, I ended up using this
rather simple workaround, in case anyone runs into this in the future:
I created a simple "wrapper" shell script with the community string
hard coded in it, then call the wrapper script instead of the
check_snmp command:
here is the one-line wrapper script: (I called it check_snmp_wrapper)
/usr/local/nagios/libexec/check_snmp -H $1 -o $2 -w $3 -c $4 -C xyz123!

then defined a new check command:
define command {
        command_name    check_snmp_wrapper
        command_line    $USER1$/check_snmp_wrapper $HOSTADDRESS$
$ARG1$ $ARG2$ $ARG3$
}

and defined my service:
define service {
        host_name                        myrouter
        service_description             check_connections
        use                                   workhours
        check_command                   check_snmp_wrapper![oid]!255000!260000
        notification_options            c,w,r,f
        contact_groups                  sysadmin
}

sometimes the answer is so simple, its staring you right in the face!
