- MutaPath.move(dst, copy_function=<function copy2>)
Recursively move a file or directory to another location. This is similar to the Unix “mv” command. Return the file or directory’s destination.
If the destination is a directory or a symlink to a directory, the source is moved inside the directory. The destination path must not already exist.
If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics.
If the destination is on our current filesystem, then rename() is used. Otherwise, src is copied to the destination and then removed. Symlinks are recreated under the new name if os.rename() fails because of cross filesystem renames.
The optional copy_function argument is a callable that will be used to copy the source or it will be delegated to copytree. By default, copy2() is used, but any function that supports the same signature (like copy()) can be used.
A lot more could be done here… A look at a mv.c shows a lot of the issues this implementation glosses over.
