Took a look at 'man bash' here.
bash --version
GNU bash, version 3.2.9(1)-release (x86_64-redhat-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.

Accoding to man bash "==" is used to test for equality and "=" is used for assignmnet.
I assume the above is a dash syntax error (dash is default on ubuntu IIRC).

Is it truly protable with "=" or do we need to be more clever?
