How about:

echo "waiting for user to hit ENTER"
while read answer; do
  if [ -z "$answer" ]; then
    break
  fi
done

or

echo "waiting for user to hit ENTER"
answer=x
until [ -z "$answer" ]; do
  read answer
done

Another try

read -p "Press any key to continue..."

Thank for your reply.
this is not what is need...
I need an echo "hit enter" running every 3 seconds till user hit enter key.

Are you sure you want this? A computer impatiently pushing the user to provide an answer may be perceived as irritating..

Yes i am sure.
I need it for a specific client and i am aware of it beeing irritating.
still the requierment is the same:
I need an echo "hit enter" running every 3 seconds till user hit enter key.

OK, try this:

answer=x
while : ; do
   echo "waiting for user to hit ENTER"
   sleep 3
done &
pid=$!
until [ -z "$answer" ]; do
  read answer
done
kill $pid

read has -t option too, u can try that also...

while [ 1 ]
do
read -p "waiting for user to hit ENTER" -t 3 var
echo $var
done

give the appropriate condition to come out of loop...

Can we have something like below?

echo 'You have selected option $varChoice. Press ENTER to continue or press ESC to choose again...'

Means, the code for ESC and re-enter the choice.
