have a look here:

• Elisp Lesson: Execute/Compile Current File
  http://xahlee.org/emacs/elisp_run_current_file.html

excerpt:

(defun run-current-file ()
  "Execute or compile the current file.
For example, if the current buffer is the file x.pl,
then it'll call “perl x.pl” in a shell.
The file can be php, perl, python, ruby, javascript, bash, ocaml,
java.
File suffix is used to determine what program to run."
(interactive)
  (let (ext-map fname suffix progName cmdStr)
    (setq ext-map ; a keyed list of file suffix to comand-line program
to run
          '(
            ("php" . "php")
            ("pl" . "perl")
            ("py" . "python")
            ("rb" . "ruby")
            ("js" . "js")
            ("sh" . "bash")
            ("ml" . "ocaml")
            ("lsl" . "lslint")
            ("vbs" . "cscript")
            ("java" . "javac")
            )
          )
    (setq fname (buffer-file-name))
    (setq suffix (file-name-extension fname))
    (setq progName (cdr (assoc suffix ext-map)))
    (setq cmdStr (concat progName " \""   fname "\""))

    (if (string-equal suffix "el")
        (load-file fname)
      (progn
        (message "Running...")
        (shell-command cmdStr)))
))
