I'm curious on this too but... emacs looks at the #! line as well as the 
suffix.  So if you do:

echo '#!/bin/bash' >
echo '#!/bin/bash' > f2.bash

and then edit them, both put you into bash mode.  And:

echo '#!/bin/bash' > f3

(no suffix) will put you into bash mode too as well as

echo '#!/usr/bin/env bash' > f4

(more complicated interpretation of the #! line)


echo '#!/usr/bin/env ruby' > f5

will put you into Ruby mode when editing f5.

My curiosity is where is all this magic done so I could tweak it if I needed 
to?  I know about file-mode-alist but that is just the suffix mapping part.  
What is interpreting the #! of a file?
