||ANSI Common Lisp 20 Files 20.2 Dictionary of
- rename-file filespec new-name defaulted-new-name,
- Arguments and Values:
- filespec - a pathname
new-name - a pathname designator other than a stream.
defaulted-new-name - a pathname
old-truename - a physical
new-truename - a physical
- rename-file modifies the file system in
such a way that the file indicated by filespec is renamed to defaulted-new-name.
It is an error to specify a filename containing a wild component, for filespec to contain a nil component where the file system does not permit a nil component, or for the result of defaulting missing
components of new-name from filespec to contain a nil component
where the file system does not permit a nil component.
If new-name is a logical
pathname, rename-file returns a logical pathname as its primary value.
rename-file returns three
values if successful. The primary value,
defaulted-new-name, is the resulting name which is composed of new-name with
any missing components filled in by performing a merge-pathnames
operation using filespec as the defaults. The secondary value, old-truename, is
the truename of the file before it was renamed. The tertiary value, new-truename, is the
truename of the file after it was renamed.
If the filespec designator
is an open stream, then the stream itself and the file associated with it are
affected (if the file system permits).
;; An example involving logical pathnames.
(with-open-file (stream "sys:chemistry;lead.text"
:direction :output :if-exists :error)
(princ "eureka" stream)
(values (pathname stream) (truename stream)))
(rename-file "sys:chemistry;lead.text" "gold.text")
- Exceptional Situations:
- If the renaming operation is not successful, an error of type file-error is
An error of type file-error might be signaled if filespec is wild.
