Yes I know how to handle them in bash, that's why I asked. If it is
printed I have to get it by quoting it with `` to get the output.

Yeh, as I suggested you always get 1, unless probably when the string
is empty. So I tried by adding the int() function! In bash by the way
the returncode can be much bigger, I think a full signed integer.
Handy to return values from functions.
