Very basic bash script to parse the log file for OpenVPN bandwidth by user

bandwidth.sh

#!/bin/bash

input_file=/var/log/openvpn/status.log

echo ""
echo "Reading $input_file"
echo ""
while read line; do
    if [[ "$line" = *,* ]]; then
        IFS=',' read -ra fields <<< "$line"    #Convert string to array
        if [[ "${fields[1]}" =~ \.[0-9]{1,3}:[0-9] ]]; then
                received=$((fields[2] / 2**20))
                sent=$((fields[3] / 2**20))
                echo "User:  ${fields[0]} from ${fields[1]}"
                echo "Since: ${fields[4]}"
                echo "Rcvd:  ${received} MB"
                echo "Sent:  ${sent} MB"
                echo ""
        fi
    fi
done < $input_file
echo ""
echo "Done reading $input_file"
echo ""

thanks!
