命令：

find -L /path/to/dir -type l 或 find /path/to/dir -follow -type l

-L     Follow symbolic links. When find examines or prints information
              about files, the information used shall be taken from the prop-
              erties of the file to which the link points, not from the link
              itself (unless it is a broken symbolic link or find is unable to
              examine the file to which the link points). Use of this option
              implies -noleaf. If you later use the -P option, -noleaf will
              still be in effect.   If -L is in effect and find discovers a
              symbolic link to a subdirectory during its search, the subdirec-
              tory pointed to by the symbolic link will be searched.

              When the -L option is in effect, the -type predicate will always
              match against the type of the file that a symbolic link points
              to rather than the link itself (unless the symbolic link is bro-
              ken). Using -L causes the -lname and -ilname predicates always
              to return false.

       -follow
              Deprecated; use the -L option instead. Dereference symbolic
              links. Implies -noleaf. The -follow option affects only those
              tests which appear after it on the command line. Unless the -H
              or -L option has been specified, the position of the -follow
              option changes the behaviour of the -newer predicate; any files
              listed as the argument of -newer will be dereferenced if they
              are symbolic links. The same consideration applies to -anewer
              and -cnewer. Similarly, the -type predicate will always match
              against the type of the file that a symbolic link points to
              rather than the link itself. Using -follow causes the -lname
              and -ilname predicates always to return false.
