There are almost certainly going to be incompatibilities with other commands. The system implemented UNIX95 plus some extensions, then they began supporting UNIX03/SUSv3/POSIX.1-2001/whatever for certain commands by using an environment variable to toggle between the incompatible behaviors. Their documentation on the UNIX03 commands indicates it is still only partially supported. For example: "cp" supports "-L" and "-P", but "cd" doesn't. > I wonder if it'd be helpful to have a low-numbered test that checks > the basics needed by the scripted Porcelains and test suite. > It would give us an easy way to answer these questions, and could > be a good way to document (in code) the capabilities we expect. I'd be in favor of something like this as well. Thanks. David P.S. In the meantime, I am handling the "cd" situation by replacing "-P" with "$PHYS" and prepending the following to t/test-lib.sh. set +o logical >/dev/null 2>&1 || PHYS=-P -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
