NAME

       cleanlinks - remove dangling symbolic links and empty directories

SYNOPSIS

       cleanlinks

DESCRIPTION

       The  cleanlinks program searches the directory tree descended from the current directory for symbolic links whose targets do not exist, and
       removes them.  It then removes all empty directories in that directory tree.

       cleanlinks is useful for cleaning up a shadow link tree created with lndir(1) after files have been removed from the real directory.

DIAGNOSTICS

       A message will be printed upon encountering each dangling symlink and empty directory.

SEE ALSO

       lndir(1).

NAME

       lndir - create a shadow directory of symbolic links to another directory tree

SYNOPSIS

       lndir fromdir [todir]

DESCRIPTION

       lndir  makes a shadow copy todir of a directory tree fromdir, except that the shadow is not populated with real files but instead with sym-
       bolic links pointing at the real files in the fromdir directory tree.  This is usually useful for maintaining  source  code  for  different
       machine	architectures.	 You  create a shadow directory containing links to the real source which you will have usually NFS mounted from a
       machine of a different architecture, and then recompile it.  The object files will be in the shadow directory, while the  source  files	in
       the shadow directory are just symlinks to the real files.

       This  has  the  advantage  that	if  you update the source, you need not propagate the change to the other architectures by hand, since all
       source in shadow directories are symlinks to the real thing: just cd to the shadow directory and recompile.

       The todir argument is optional and defaults to the current directory.  The fromdir argument may be relative (e.g., ../src) and is  relative
       to todir (not the current directory).

       Note that RCS, SCCS, and CVS.adm directories are not shadowed.

       Note  also  that if you add files, you must run lndir again.  Deleting files is difficult because the symlinks will point to places that no
       longer exist.

BUGS

       The patch routine needs to be able to change the files. You should never run patch from a shadow directory.

       Use a command like the following to clear out all files before you can relink (if the fromdir has been moved, for instance):

	    find todir -type l -print | xargs rm

       The following command will find all files that are not directories:

	    find . ! -type d -print
