Case question
Hi,
ksh script.

I have a shell script which use while loop and case statment in order to execute several functions.
Each step is working fine .
I want to add a new dynamic option : from step X to step Y which go through the selected steps .
for example : from step 2 to 3 , will execute option 2+3 only (function 2 and function 3) in the menu bellow.

Please advise.
Thanks

Code:
while :
do
  clear
  echo "----------------------------------------------"
  echo " * * * * * * * Steps * * * * *  * * "
  echo "----------------------------------------------"
  echo "[1]  Step1 "
  echo "[2]  Step2 "
  echo "[3]  Step3 "
  echo "[0]  Exit  "
  echo "----------------------------------------------"
  echo -n "Choose Option [0-3]:"
  read yourch
  case $yourch in
    0) exit 0
       ;;
    1)  function1 ;;
    2)  function2 ;;
    3)  function3 ;;
    *) echo " Please select choice 1,2,3 OR all"
    echo "Press a key. . ."
       ;;
  esac
done

You could insert the following code in red:-
Code:
while :
do
  clear
  echo "----------------------------------------------"
  echo " * * * * * * * Steps * * * * *  * * "
  echo "----------------------------------------------"
  echo "[1]  Step1 "
  echo "[2]  Step2 "
  echo "[3]  Step3 "
  echo "[0]  Exit  "
  echo "----------------------------------------------"
  echo -n "Choose Option [0-3]:"
  read yourch
  until [ $yourch -ge 4 ]
  do
    case $yourch in
      0) exit 0        ;;
      1)  function1 ;;
      2)  function2 ;;
      3)  function3 ;;
      *) echo " Please select choice 1,2,3 OR all"
      echo "Press a key. . ."
         ;;
    esac
    ((yourch=$yourch+1))
  done
done

You would need to make sure that yourch is numeric, else you will get all sorts of horrible errors.



Does this help?

Hi Robin,
Thank you for your quick feedback.
Its will work fine in case i will go through all the steps.
In reality i have more than 10 steps. To keep this senario simple i have mentioned steps 1-3 .
Its will not solve the problem in case i need to run just between steps 2-3 ( or between any other steps which are not all the steps).
Thanks again for sharing you time.

So basically you want to be able to type say
Code:
2 4

and the script will execute steps 2,3 and 4?

1 to 4 , 2 to 4 , 3 to 4 and each
Thanks Again

In ksh93 and bash4 you can use fall through, using ;&:
Code:
case $yourch in
    0)  exit 0 ;;
    1)  function1 ;&
    2)  function2 ;&
    3)  function3 ;&
    4)  function4 ;;
    *)  echo " Please select choice 1,2,3 OR all"
        echo "Press a key. . ."
        ;;
esac
