Hey, all.

I am trying to set a string at the head of the file and use it in different places in the file.

Everything works correctly for somethign like ruby, but I am not sure how do do this with a shell command.

Just sets the string to the url
#+NAME: url_name
#+BEGIN_SRC ruby
"http://www.google.com"
#+END_SRC

#+RESULTS: url_name
: http://www.google.com

#+BEGIN_SRC ruby :var url_input=url_name
url_input
#+END_SRC

#+RESULTS:
: http://www.google.com

^^ This seems to work fine.

#+BEGIN_SRC shell :var url_input=url_name
  curl url_input
#+END_SRC

#+RESULTS:

^^ This doesn't work. It is trying to use "url_input" in the curl command.

#+BEGIN_SRC shell
  curl {url_input}
#+END_SRC

#+RESULTS:

^^ this doesn't work. It is trying to use "url_input" in the curl command.

Thanks!
