     -V,   --version      Print version number and exit
--------------- Error Options ---------------
     --enable-error-stack Prints messages from the HDF5 error stack as they occur.
                          Optional value 2 also prints file open errors.
                          Default setting disables any error reporting.
--------------- File Options ---------------
     -f, --file            Print file information
     -F, --filemetadata    Print file space information for file's metadata
     -s, --freespace       Print free space information
     -S, --summary         Print summary of file space information
     --page-buffer-size=N Set the page buffer cache size, N=non-negative integers
     --endpoint-url=P     Supply S3 endpoint url information to "ros3" vfd.
                          P is the AWS service endpoint.
                          Has no effect if filedriver is not "ros3".
     --s3-cred=<cred>     Supply S3 authentication information to "ros3" vfd.
                          <cred> :: "(<aws-region>,<access-id>,<access-key>)"
                          <cred> :: "(<aws-region>,<access-id>,<access-key>,<session-token>)"
                          If absent, <cred> -> "(,,)" or <cred> -> "(,,,)", no authentication.
                          Has no effect if filedriver is not "ros3".
     --hdfs-attrs=<attrs> Supply configuration information for HDFS file access.
                          For use with "--filedriver=hdfs"
                          <attrs> :: (<namenode name>,<namenode port>,
                                      <kerberos cache path>,<username>,
                                      <buffer size>)
                          Any absent attribute will use a default value.
     --vol-value          Value (ID) of the VOL connector to use for opening the
                          HDF5 file specified
     --vol-name           Name of the VOL connector to use for opening the
                          HDF5 file specified
     --vol-info           VOL-specific info to pass to the VOL connector used for
                          opening the HDF5 file specified
                          If none of the above options are used to specify a VOL, then
                          the VOL named by HDF5_VOL_CONNECTOR (or the native VOL connector,
                          if that environment variable is unset) will be used
     --vfd-value          Value (ID) of the VFL driver to use for opening the
                          HDF5 file specified
     --vfd-name           Name of the VFL driver to use for opening the
                          HDF5 file specified
     --vfd-info           VFD-specific info to pass to the VFL driver used for
                          opening the HDF5 file specified
--------------- Object Options ---------------
     -g, --group           Print group information
     -l N, --links=N       Set the threshold for the # of links when printing
                           information for small groups.  N is an integer greater

     -m N, --dims=N        Set the threshold for the dimension sizes when printing
                           information for small datasets.  N is an integer greater
                           than 0.  The default threshold is 10.
