% mkdir something % ln -s something something_elseOn Mac OS X in the shared directory, do this:
% cd something_else % touch test_file % mv test_file ../something mv: rename test_file to ../something/test_file: No such file or directoryWatch it all go bye-bye.
I guess there are still bugs with the mv command. It should have said that the files were the same. If I realized that the directory that I was working in was a soft link to the main directory, I would not have tried to move the files.
[robg adds: Unix wizards, is this expected behavior out of mv? It seems wrong to me, but I don't know enough about what's normal in Unix...]
