portarray=(`/usr/bin/netstat -tnpl|grep -v '@pts\|cpus\|master'|awk '/^tcp/{sub(/.*:/,"",$4);sub(/[0-9]*\//,"",$7);if(NF==7)print $4,$7;else print $4,$7,$NF}'|sed 's/[ ][ ]*/:/g'|sort -n |uniq`)

length=${#portarray[@]}

echo "{"

echo "    \"data\":["

for ((i=0;i<$length;i++))
do

        PORT_NUM=`echo ${portarray[$i]} | awk -F : '{print $1}'`
        PORT_NAME=`echo ${portarray[$i]} | awk -F : '{print $2$3}'`
        echo '        {'
        echo "            \"{#PORT_NUM}\":\"${PORT_NUM}\","

        echo "            \"{#PORT_NAME}\":\"${PORT_NAME}\""

        if [ $i -lt $[$length-1] ];then
        echo '        },'
        fi
done

echo '        }'
