What do you mean with "In /bin/bash it dumps help text"? do you mean
in "/bin/echo --help"?

In bash, "echo" refers to the "echo" builtin, which does not have a
--help option because it's not calling an external program:

I was wondering about why /bin/echo (e.g. from GNU coreutils) even
exists when the posix shell has an echo builtin, and this post has
some reasoning behind that:
