## ldd

    ldd [option] file

List dynamic dependencies; that is, list shared objects that would be loaded if `file` were executed. (If a valid `file` needs no shared objects, ldd succeeds but produces no output.) In addition, ldd's options can be used to show unresolved symbol references that would result from running `file`. Specify only one option.

### Options

-d

  Check references to data objects only.

-r

  Check references to data objects and to functions.
