Hey guys,
Regarding this: http://orgmode.org/manual/Batch-execution.html
I also had success using --script, as in:
#!/Applications/Emacs.app/Contents/MacOS/Emacs --script
In the top of a .el file. You can then chmod it to be executable and run it.
Just thought I'd share, as an alternative, but I'm not sure if there are
any subtle differences, though.
Cheers,
- Marcelo.

Would you mind sharing a simple .el file you'd use that way? The
site's example is a bash script, and I wonder how much cleaner a .el
file would be.

Sure!
Bear in mind I'm not an elisp expert, and I got it working after a lot of
trial and error. I'm using this script as part of a quickblogging engine
I'm writing for org (still testing, will share once it works as expected)
so that I can blog from directly from my journal org file to a jekyll blog.
I also created a new function based off org-export-generic called
org-export-generic-markdown which can be called in a non-interactive way,
so that it could work from the script.
The script basically exports a specific org file to markdown (in the same
dir the org file is located). Now I want to make it accept command-line
arguments. I will check it out tonight.
Here it goes:
http://pastie.org/4611632
This is pretty powerful, as you can also return data from the script by
using princ. I can imagine millions of ways this could be used to integrate
org with other apps/languages.

NB: While org-export-generic.el was handy for a while, developers should
not rely on it write new code. It is obsoleted by org-export.el.

Hi Bastien,
I suggest you put a notice at the top of org-export-generic.el with this
notice and suggest future developers use org-export.el instead.

Bernt

Marcelo posted a larger example, but maybe a very small example might be
helpful. Put the following in some file (I called it hello.el but the
name does not really matter):
--8<---------------cut here---------------start------------->8---
#! /usr/local/bin/emacs --script
(message "Hello World!")
--8<---------------cut here---------------end--------------->8---
Make it executable:
chmod +x hello.el
and run it:
./hello.el

Hi Nick,
Thanks for turning it into a concise example :)
Is that somewhere in the manual or Worg? Perhaps it should be added. I
never contributed to Worg, I will look into how tonight.
This is a subject that should be explored more. I see a lot of potential in
having CLI .el scripts (i.e taking the emacs GUI out of the equation).
- Marcelo.

I once asked a related question on stackoverflow, and recieved this
answer that shows how to
- become more independent of the location of the emacs executable
- pass more than one argument on the shebang line
at the same time:
,-----------------------------------------------------------------------------
| Many unix variants only allow a single argument to the program on
| the shebang line. Sad, but true. If you use #!/usr/bin/env emacs so
| as not to depend on the location of the emacs executable, you can't
| pass an argument at all.
|
| Chaining scripts is a possibility on some systems, but that too is
| not supported everywhere.
|
| You can go the time-honored route of writing a script that is both
| a shell script and an Emacs Lisp script (like Perl's if
| $running_under_some_shell, for example). It sure looks hackish, but
| it works.
|
| Elisp comments begin with ;, which in the shell separates two
| up commands. So we can use a ; followed by a shell instruction to
| vote switch over to Emacs, with the actual Lisp code beginning on the
| 21 next line. Shells don't like an empty command though, so we need to
| down find something that both the shell and Emacs treat as a no-op, so
| vote put before the ;. The shell no-op command is :; you can write it
| ":" as far as the shell is concerned, and Emacs parses that as a
| constant at top level which is also a no-op.
|
| #! /bin/sh
| ":"; exec emacs --no-site-file --script "$0" -- "$@" # -*-emacs-lisp-*-
| (print (+ 2 2))
`-----------------------------------------------------------------------------

The --script is described in the emacs manual, but no example is
provided. Adding it to Worg (maybe with a two-stage explanation:
trivial "Hello World" example, followed by an org-specific example)
is a good idea.
For contributing to Worg, see the "Maintenance of Worg" section:
http://orgmode.org/worg/#sec-4

Note that you could do this even before --script was invented:
emacs --batch -l /path/to/somefile.el
is exactly equivalent to the --script invocation of somefile.el, which
in turn is more or less[fn:1] equivalent to stuffing the above command
line into a bash script file, making *that* executable and running it.
The --script method is a bit more convenient but it is just "syntactic
sugar".
Nick
Footnotes:
[fn:1] There is an extra fork/exec of bash in this method, but that's about it.
