go's version is this which is my favorite because a single http server serving static files is cool but it's better to program it to do what you want.

    package main

    import (
        "net/http"
        "os"
    )

    func main() {
        if err := http.ListenAndServe(os.Args[1], http.FileServer(http.Dir(os.Args[2]))); err != nil {
            panic(err)
        }
    }
