Pause before exit
Code:
 6) printf "\n GoodBye! \n\n"; exit ;;

I am trying modify the above command to pause a couple of seconds before exiting, so a message can be displayed. Thank you Smilie.

Hi,

Quick way is;

Code:
6) printf "\n GoodBye! \n\n"; sleep 2 ; exit ;;

Regards

Hi

You could also put a trap in your script which will catch the EXIT signal (0), and wait for the [enter] key:
Code:
trap 'printf "\n GoodBye! \n\n"; read n' 0

or just wait for sleep to time out
Code:
trap 'printf "\n GoodBye! \n\n"; sleep 6' 0

Slightly different approach giving a 5 second delay with keyboard override:-
Code:
 6) printf "\n GoodBye! \n\n"; read -n1 -s -t5; exit ;;

I'm missing the point of this thread. Exiting a shell script doesn't clear the screen. If you don't want to clear the screen for a few seconds after the script exits, why are you clearing the screen after your script exits???
