How to tell which *.el file loaded?

How to tell which *.el file loaded?

[bill]

Is there a simple way to confirm which of several possible foo.el
files in the system was loaded by (require 'foo) ?  (I'm thinking
along the lines of something I can stick in the desired foo.el that
will confirm to me that it was it that was loaded by (require 'foo)
.)

Thank you,

	-bill

Doing (locate-library "foo") will tell you which foo.el or
foo.elc Emacs found.  Emacs prefers byte-compiled (foo.elc) over
source (foo.el) files, so, should you modify foo.el, and a
foo.elc exists, you'll have to recompile it.

You can also look at the output of

M-x list-load-path-shadows RET

(message "Hi, I'm here.")
(sleep-for 3)           ; 3 seconds

Please note that Emacs will load the *.elc file, if it exists.  That
is, you may wish to re-byte-compile your foo.el, if it was
byte-compiled before.

You may as well do:

(message "Hi, my name is %s" load-file-name)
