Please provide a reason for the change...

= is for variable assignment and == for conditions

[angristan]

That's simply no true, otherwise the script would be completely broken :)

== is a bash-ism, by the way. It's better to use the POSIX =. In bash the two are equivalent, and in plain sh = is the only one guaranteed to work.

Well this bash-ism is default on a lot of languages and this script is #!/bin/bash. But it's good to know it works because it's a POSIX standard.

This script only works in bash, because all the [[ ... ]] would not work in sh.
So, If you use [[ ... ]], then should also use ==. My small comment.
