[Babel] Blank line preceeds tangled data

[Babel] Blank line preceeds tangled data

[Bernt Hansen]

Hi,

When I tangle some file such as

#+begin_src sh :tangle x.sh
  #!/bin/sh
  echo done
#+end_src

I get the following output which includes a blank line up front.

,----[ x.sh ]
| 
| #!/bin/sh
| echo done
`----

Doesn't this break the shebang line on unix?  I don't think the leading
blank line should be in the tangled output.

Regards,
Bernt

Not sure why it's there (I'm sure Eric S. will enlighten us)
but you can get rid of it with :padline no.

and there is also the :shebang parameter to specify the shebang, so


#+begin_src sh :tangle x.sh :shebang #!bin/sh :padline no
 echo done
#+end_src

will give you the expected file x.sh. No idea why it is not enabled in your
config.

Cheers,

Thanks Rainer and Nick!

I didn't know about either of these babel options.

The :shebang line works for me.
