unable to set variable in case statement bash

Question

I\'m trying to set a variable based on a bunch of input conditions. Here\'s a small sample of the code:

#!/bin/bash
INSTANCE_SIZE=\"\"
case \"$1\" in
   \"m         


        

Answer 1

You need to remove the $ sign in the assignments - INSTANCE_SIZE="m1.small". With the dollar sign, $INSTANCE_SIZE gets substituted with its value and no assignment takes place - bash rather tries to execute the command that resulted from the interpolation.
