Please complete this program.

Hi All,

I need some help to complete the below script, after executing below script blank lines are coming, but i am expecting 4 digit numeric no. Please solve the issue ASAP.

function portno { while (true) do random=`echo $RANDOM | cut -c 1-4` port=`netstat -a | grep -c $random` if [ $port -ne 1 ]; then break else continue fi done return $port } port1=`portno` port2=`portno` echo "$port1" echo "$port2"

Code:

function portno
{
while (true)
do
random=`echo $RANDOM | cut -c 1-4`
port=`netstat -a | grep -c $random`

if [ $port -ne 1 ];
then
        break
else
        continue
fi
done
return $port
}

port1=`portno`
port2=`portno`

echo "$port1"
echo "$port2"

-->

Code:

function portno
{
while (true)
do
random=`echo $RANDOM | cut -c 1-4`
port=`netstat -a | grep -c $random`

if [ $port -ne 1 ];
then
        break
