Hi, I have wrote a shell script and defined in exec module. exec get_streaming_data_usage { wait = yes program = "/bin/bash /scripts/get_streaming_data_usage.sh %{Framed-IP-Address}" input_pairs = request #output_pairs = reply shell_escape = yes #output = file } And I am executing in /usr/local/etc/raddb/sites-enabled/default get_streaming_data_usage Script is as follows: [root@freeradius ~]# cat /scripts/get_streaming_data_usage.sh #/bin/bash #get the framed IP_address: framed_ip_address = $1 #Get the usage in bytes: data_usage = `grep "$framed_ip_address" /scripts/user-bandwidth.txt | cut -d , -f 4` How can I get the value of data_usage inside the file /usr/local/etc/raddb/sites-enabled/default Please help -- Randeep Mob: +919447831699[kerala] Mob: +919880050349[B'lore] http://twitter.com/Randeeppr http://in.linkedin.com/in/randeeppr [image: --] Randeep Raman [image: http://]about.me/Randeeppr <http://about.me/Randeeppr>
