      -f, --flag         Flag type

      Flag type is one of the following strings:

      shallow     Copy only immediate members for groups

      soft        Expand soft links into new objects

      ext         Expand external links into new objects

      ref         Copy references and any referenced objects, i.e., objects
                  that the references point to.
                    Referenced objects are copied in addition to the objects
                  specified on the command line and reference datasets are
                  populated with correct reference values. Copies of referenced
                  datasets outside the copy range specified on the command line
                  will normally have a different name from the original.
                    (Default:Without this option, reference value(s) in any
                  reference datasets are set to NULL and referenced objects are
                  not copied unless they are otherwise within the copy range
                  specified on the command line.)

      noattr      Copy object without copying attributes

      allflags    Switches all flags from the default to the non-default setting

      These flag types correspond to the following API symbols

      H5O_COPY_SHALLOW_HIERARCHY_FLAG
      H5O_COPY_EXPAND_SOFT_LINK_FLAG
      H5O_COPY_EXPAND_EXT_LINK_FLAG
      H5O_COPY_EXPAND_REFERENCE_FLAG
      H5O_COPY_WITHOUT_ATTR_FLAG
      H5O_COPY_ALL
