exit 0 in shell script is exiting from session

Hi All,

I have a menu driven script which exits on a switch case statement as below

Please let me know what is the problem with the exit statement given in the code snippet. When I select option 5 on the menu, I get logged off the linux session

while :
do
 clear
 echo "                         MAIN M E N U"
 echo "         1. Get files"
 echo "         2. Run Application"
 echo "         3. Delete files "
 echo "         4. Do ALL of the above"
 echo "         5. Exit"
 echo "                                                                 "
 echo "                                                                 "
 echo -n "Please enter option [1 - 5]"
 read opt
 case ${opt} in
  1) echo "Getting files ";
     get_files
        ;;
  2) echo "Executing Application";
     executeapp
        ;;
  3) echo "Deleting files older than 2 weeks in directory";
     delete_files;
        ;;
  4) echo "Doing everything!";
        get_files;
        executeapp;
        delete_files;
        ;;
  5) exit 0;
        ;;
  *) echo "$opt is an invaild option. Please select option between 1-5 only";
     echo "Press [enter] key to continue. . .";
     read enterKey
        ;;
esac
done

how do you invoke the script, and what do you want to happen when you select option 5 on the menu?

Tintin

If you get logged off when you select option 5, it means it is most likely invoked from your .profile

with something like

exec /path/to/menu.sh

The exec will overlay the current process (in this case the login) with menu.sh, so that when you exit the menu, you are immediately logged off.

You need to change your .profile to just call the menu without the exec, eg:

/path/to/menu.sh
