% touch foo foo
% cp -u foo foo && echo yes
cp: `foo' and `foo' are the same file
I expected that since -u says
-u, --update
copy only when the SOURCE file is newer than the
destination file or when the destination file is missing
it would not attempt to copy the file in this case (since the file is
not newer than itself) and cp would return a true exit status.
