you can use:

echo "Press ENTER to continue"
read somevar

Then you will need to press ENTER for the script to continue. Is this what you mean?

If the script is running in the foreground, it doesn't need any other interrupting for it
 to respond to keyboard commands involving the control key, such as ^Z (suspend) or ^C (stop). If you want, however, your script can be put into a `while` loop that will cause it to execute only when you press the ENTER key.

while [[ -z $(read Varname) ]]; do

Can you help with this problem?
