Subject: "su user -c 'command'" from within ruby

Hi,

I want to invoke a shell command from within ruby but as another user in
a Linux environment. I start the ruby script itself as root and in the
script I do something like this:

%x{su some_user -c "some_command"}

some_more_ruby_stuff

The problem is: 'some_command' gets successfully executed, but the ruby
script seems to never return to normal operation. 'some_more_ruby_stuff'
gets never executed.

Could anyone tell me why this happens and maybe what I could do about it?

Regards,
Moritz
