cleanlinks - remove dangling symbolic links and empty directories
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.
RELATED
lndir(1).
