No physical check on the filesystem, but a logical cleanup of a path. On UNIX eliminated successive slashes and successive "/.".
($volume,$directories,$file) = File::Spec->splitpath( $path );
($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );Splits a path in to volume, directory, and filename portions. Assumes that the last file is a path unless the path ends in '/', '/.', '/..' or $no_file is true. On Win32 this means that $no_file true makes this return ( $volume, $path, undef ).
Separators accepted are \ and /.
Volumes can be drive letters or UNC sharenames (\\server\share).
The results can be passed to "catpath" to get back a path equivalent to (usually identical to) the original path.
The opposite of catdir().
@dirs = File::Spec->splitdir( $directories );$directories must be only the directory portion of the path on systems that have the concept of a volume or that have path syntax that differentiates files from directories.
Unlike just splitting the directories on the separator, leading empty and trailing directory entries can be returned, because these are significant on some OSs. So,
File::Spec->splitdir( "/a/b//c/" );Yields:
( '', 'a', 'b', '', 'c', '' )Takes volume, directory and file portions and returns an entire path. Under Unix, $volume is ignored, and this is just like catfile(). On other OSs, the $volume become significant.
