RE: Bash Script Not Exiting...



### Prevent Ctrl-C from getting out of the menu to the command line
trap exit SIGINT

### Loop forever...or at least until told to exit
while [ /bin/true ]; do
  clear
  ${ECHO}
  ${ECHO} "Choose what you would like to do"
  ${ECHO} "    1 - Change Password"
  ${ECHO} "    2 - Clear Print Queue"
  ${ECHO} "    3 - Stop Printer and Reject Jobs"
  ${ECHO} "    4 - Start Printer and Accept Jobs"
  ${ECHO} "    5 - Log out"
  ${ECHO} "Option: "
  read ans
  case $ans in	
          1) sudo /usr/bin/password2
             ;;
          2) sudo /u/.scripts/printer
             ;;
          3) sudo /u/.scripts/stopprinter
             ;;
          4) sudo /u/.scripts/startprinter
             ;;
          *) exit
             ;;
  esac
done
	
With this you should be able to remove the 'continue' function within
each of the scripts.  When the task is completed, the user should be
prompted with the original menu and they can switch tasks without ever
leaving the original .bash_profile.
