This sounds like you might benefit from taking a Linux shell tutorial.

If you run "foo" and get one error message and run "./foo" and get a different error message, that suggests that you are running two different "foo" executables. For example, it might mean that "foo" is found early in your PATH, and is *not* the "foo" that is in your current working directory. But when you run "./foo", you're forcing the use of the "foo" in your current working directory. It sounds like the former one is broken, but the latter one works.

Gus also noted some good points in his reply.
