  pathname
       
           (Or "path") The specification of a node (file or
          directory) in a hierarchical file system.  The path is
          usually specified by listing the nodes top-down, separating
          the directories by the pathname separator ("/" in Unix,
          "\" in MS-DOS).
       
          A pathname may be an absolute pathname or a relative
          pathname.  The part of the pathname of a file after the last
          separator is called the basename.
