The following options modify how
traverse a hierarchy when the --recursive (-R)
option is also specified.
If more than one of the following options is specified, only the final
one takes effect.
These options specify whether processing a symbolic link to a directory
entails operating on just the symbolic link or on all files in the
hierarchy rooted at that directory.
These options are independent of --dereference and --no-dereference (-h), which control whether to modify a symlink or its referent.
If --recursive (-R) is specified and a command line argument is a symbolic link to a directory, traverse it.
In a recursive traversal, traverse every symbolic link to a directory that is encountered.
Do not traverse any symbolic links. This is the default if none of -H, -L, or -P is specified.
