Reg exec module

[J@g@dee5h]

Hello team,

I am stuck with exec module. Need to run a script with radius exec module.

I have defined this script in sites-enabled/default file as below

get_streaming_data_usage := `/scripts/get_streaming_data_usage.sh
%{Framed-IP-Address}`

get_streaming_data_usage.sh file contains

#/bin/bash

#get the framed IP_address:
framed_ip_address = $1
#Get the usage in bytes:
get_streaming_data_usage = `grep "$framed_ip_address"
/scripts/user-bandwidth.txt | cut -d , -f 4`


But I am getting the error as "Exec format error" in debug log. Please find
the debug log as below.
