NAME

       revpath - generate a relative path that can be used to undo a change-directory

SYNOPSIS

       revpath path

DESCRIPTION

       The  revpath  program  prints  out a relative path that is the ``reverse'' or ``inverse'' of path.  Start
       with two directories top and bottom, with the latter below the former, and path is the location of bottom
       relative  to  top.   The output of revpath is the location of top relative to bottom.  The resulting path
       contains a trailing `/' character when the result is non-trivial.  If path  is  equivalent  to  `.',  the
       resulting  output  is  empty.   If  path  is  invalid  in some way (e.g., doesn't represent the path to a
       subdirectory) the output is also empty and no error messages are ever generated.

DIAGNOSTICS

       There are no diagnostics.  Error conditions are silently ignored, and the exit status is always 0.

BUGS

       It isn't possible to reverse arbitrary relative paths.  If any path element between the two end points of
       path is a symbolic link, the results will probably be incorrect.
