Is executing a file platform dependent?

> I was wondering if it is true that executing a file from within Pharo is platform dependent. I don't actually need to execute a file; it's more a theoretical question and I have no idea what the mechanisms are that would be used. To give you a clearer picture: Imagine you have C, sh, and perl files. What I'm thinking about is that I would have some data in the image that I would want to process with the code in one of those files. I would then wait for the result and process the result in the image.
