Using ncdump on netCDF-4 files

15.6 Using ncdump on netCDF-4 files

The ncdump utility emits extended CDL for netCDF-4 files.

Tow command-line options for ncdump related to netCDF-4 files are:

[-g  grp1,...]   output data only for sepecified groups

[-s]		    output special virtual attributes that provide
                                    performance-related information for netCDF-4 data

Example: from foo.cdl, output data only for group "FooGrp" and all special attributes:

$ ncdump -g FooGrp -s foo.cdl

Note: the "-k" option is not needed if the type of outputt file can be deduced from the input. For example, i the input CDL has groups, the output must be a netCDF-4 file, so that's what ncgen will generate.
