What is the function to move files? I want to emulate the following shell command:

mv file dir

As described here, the closest is rename-file, but this would be emulating this:

mv file newfile

1 Answer 1


That function can actually move files to directories, but its documentation was not in accord with its features. If the destination ends in a /, then the file is moved. e.g.

(rename-file "foo" "bar/")

will move foo into the directory bar.

  • is a slash portable? How to build a dirname from a string in a portable way?

    (file-name-as-directory "bar") is the portable way to do that.
