while this is true for the particular piece of code quoted, in general, this 
statement is false.  "==" is a bashism (it is not part of POSIX), and it 
allows you to do comparisons that the "=" operator does not (such as pattern 
matching).

this code uses "=" everywhere with single brackets.  any new code should stick 
to that form.  if you want to use "==", it should be with double brackets, and 
probably have a good reason for it.
