Shell Programming and Scripting

i have a case statement which branches to different sections based on an input. Each branch needs to call a function. below is the code. FOr some reason, the code inside the function is not getting executed. the code is below for reference.

in the below code echo "Function 1" which is there inside the function does not get executed. please let me know the fix for the same. thanks

Code:

#!/bin/ksh
function fn_1
{
echo "Function 1"
}
function fn_2
{
echo "Function 2"
}
ARG=DQ
case $ARG in
                DQ)
   fn_1()
                ;;
         MP)
   fn_2()
                ;;
                *)
  echo "Others"
                ;;
esac

Lose the trailing brackets when calling the function. Should be:

Code:

 fn_1
 fn_2

It doesn't get executed because it's going into the DQ section, not the MP one. Cases end at ;;

You call a function like functionname, not functionname(), incidentally.
