Can you help to improve it? Just send fixes for the redirection in separate patch first and then patch that fixes the finger return value. -- Cyril Hrubis chru...@suse.cz ------------------------------------------------------------------------------ November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.
