Probably submodules are a better way to accomplish the larger goal of what you're doing here (you'd put the call to 'echo' in, say, a main submodule), but just in case they aren't, here's the precise commandline you need:
$ racket -t echo.rkt -l racket/base -e '(echo 1)' 1 Although you'd successfully exported "echo" to a place where a "-e" command-line argument can find it, you'd not exported a notion of function application. Adding -l racket/base exports racket's notion of function application.
