Yes, shows my working directory.

This is great! Actually this solves my problem which means: create a link
to the file and set results to silent.

This does not compile, the compiler complains about missing arguments.
I have to write it like this:

plot.savefig("file.svg", format='svg')

Works as exspected.

So, just to mention the current state of affairs (with a simple
example):

--8<---------------cut here---------------start------------->8---
#+begin_src python   :results output
from pylab import *

t = arange(0.0, 2.0, 0.01)
s = sin(2*pi*t)
plot(t, s)
show()
savefig("file.svg", format='svg')
#+end_src
--8<---------------cut here---------------start------------->8---

The above code works. But if I set `:file' to `file.svg' with every
evaluation the link to the file is placed after #+RESULTS: but the
file itself is empty. If the code is evaluated without `:file
file.svg' the evaluation simply works and the file.svg appears in the
working directory.
