Hello all,
If I evaluate the following source block in emacs 23.1.1, org mode v7.8.03 it reports that it produces no output:
#+begin_src sh :results replace
foo=1
if [[ -n "$foo" ]]; then
echo "foo has been defined (and has value $foo)"
else
echo "foo has not been defined"
fi
if [[ -n "$bar" ]]; then
echo "bar has been defined (and has value $bar)"
else
echo "bar has not been defined"
fi
#+end_src
Confusingly if I remove either if block then the results for the remaining one is correct and if I run the same code from within an actual script it works as I expect (foo is defined, bar is not). Can anybody provide any clues about what I'm doing wrong.
Thanks in advance
Phil

I believe adding :results output should fix this problem, as what you
want is a collection of the text printed to STDOUT.
With that change I get the following...
#+begin_src sh :results replace output
foo=1
if [[ -n "$foo" ]]; then
echo "foo has been defined (and has value $foo)"
else
echo "foo has not been defined"
fi
if [[ -n "$bar" ]]; then
echo "bar has been defined (and has value $bar)"
else
echo "bar has not been defined"
fi
#+end_src
#+RESULTS:
: foo has been defined (and has value 1)
: bar has not been defined
