As the autoconf world has proven, it's better to test for features (will THIS action work?) than for versions (am I on shell XYZ version ABC?). Rather than figuring out "is this script running under bash", focus on "what can I test up front to learn if the rest of my script can rely on a certain feature being present", repeated for each feature that is not in common to all shells. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
