i just made my first attempt to write a shell script on RH 7.2.
I want to provide admins in other cities (who don't know much about linux) with manu-based access to Linux NTP server running on our site. The problem with the script is that I need the result of commands to be displayed on the screen with option to hit enter and return to main manu (which I don't know how to do)
while true
echo " NTP MENU "
echo "--------------------------------------------"
echo " Select one of the following:"
echo " 1. NTP communication status "
echo " 2. Check if NTP daemon is running"
echo " 3. Restart NTP daemon"
echo " 4. Exit"
echo " Press 1,2,3, or 4 and Enter"

read Keypress

case "$Keypress" in
1 ) /usr/sbin/ntpq -p ;;
2 ) /bin/ps -ef | grep ntp ;;
3 ) /sbin/service ntp restart ;;
4 ) /usr/bin/clear
/bin/echo "Bye-bye!"
exit ;;


Can anyone help me regarding my question?
