Shell Programming and Scripting

Hi All,

I have one requirement in my automation .

I need to pass values like 1 , 2 , 3 to MY_IMAGE in command line in linux .

I had defines activities for all these inputs in other make file.

The code similar to below i wrote for my requirement. Issue was whenever i passes values like MY_IMAGE=1 , MY_IMAGE=2 ,MY_IMAGE=3 it's printing only echo ACT_DO=XYZ;

It's not displaying the other info whenever i selected 2 or 3 .can any one check and correct my code .thanks in advance.

Code:

 export MY_IMAGE
 MY_IMAGE=$img_value;
  if [ $img_value :="1" ]
 then
     echo ACT_DO=XYZ;
 else 
  if [ $img_value :="2 ] 
    then
     echo ACT_DO=ABC;
 else 
  if [ $img_value :=3 ] 
    then
     echo ACT_DO=ETC;
 else
    echo ""$img_value" is unsupported";
    exit 1; 
     fi
 fi
fi
