Why equal to operator does not work if it is not surrounded by space?

Question

I tried the following script

#!/bin/bash
var1=\"Test 1\" 
var2=\"Test 2\"
if [ \"$var1\"=\"$var2\" ] 
  then 
    echo \"Equal\" 
  else 
    echo \"Not equa         


        

Answer 1

To add to the existing explanation, "$var1"="$var2" is just a single non-empty string, and thus always evaluates as true in a conditional.

[ "$var1"="$var2" ] && echo true

The above command will always print out true (even if var1 and var2 be empty).
