i don't know why the shell does not unquote here:
#+BEGIN_SRC sh :results verbatim output :var how="a 'b' \c \"d\" e"
:var dothis="echo \"hi\""
echo $how
$dothis
#+END_SRC
#+RESULTS:
#+begin_example
a 'b' c "d" e
"hi"
#+end_example
thanks.

Use org-babel-expand-block (C-c C-v v) to view the code block with the
variable expansion.

hi eric,
say you want to list 2 files: "1 space" and "nospace".
#+call: list(how="\"1 space\" nospace")
#+name: list
#+BEGIN_SRC sh :noweb yes :results verbatim output
{
# this fails
# ls $how
# this would work, if there were a call option to support it
# ls <<how>>
} 2>&1
:
#+END_SRC
is there?

You can't mix noweb and variable calling. You could pass the files in
using either of the following techniques.
#+name: files-tab
| with space |
| nospace |
#+name: files-ex
: with space
: nospace
#+name: list
#+begin_src sh :var files="" :results verbatim
IFS="
"
for file in $files;do
echo "-|$file|-"
done
#+end_src
#+call: list(files-tab)
#+RESULTS:
: -|with space|-
: -|nospace|-
#+call: list(files-ex)
#+RESULTS:
: -|with space|-
: -|nospace|-

thanks for the examples, but they don't meet my needs as tables for
each set of arguments would be too unwieldy.
what would be ideal is to allow setting noweb expansions in the call
line (instead of requiring named blocks to provide the expansion).
i.e. it is similar to setting a var, but is a noweb setting instead.
then i would just do the call with the files i want, quoted the way i want.
may i make this a feature request?

How about this.
#+name: list
#+begin_src sh :var files="" :results verbatim
IFS="
"
for file in $files;do
echo "-|$file|-"
done
#+end_src
#+call: list("1 space\nnospace")
#+RESULTS:
: -|1 space|-
: -|nospace|-

I'm not sure that the additional utility justifies the added complexity.

hi eric,
the object is to make the code inside a babel shell block as similar
to a real shell script as possible. also, calling it using #+call
should be like calling it from another shell script.
this isn't possible in babel at present.
the script cannot use "$@" for its positional parameters. it could
use <<noweb>>, but that requires the creation of an extraneous block
merely to do a call, instead of supplying the value in the call line.
if making this possible is not desirable, then i will not request it,
but i wanted to explain why this object is not achieved with existing
babel options that i am aware of.
thanks.

A couple of languages already support a :cmdline header argument. I've
just added shell block support for :cmdline, so the following is now
possible.
#+begin_src sh :cmdline "foo bar baz"
echo $2
#+end_src
#+RESULTS:
: bar

I hope the above is sufficient, if not I'm not personally able to do
much more on this front, although I'm always happy to review patches.
