linux下查詢無效的符號連線(轉)

-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.
