Use of ncdump and ncgen together can accomplish some simple data management tasks. Format conversion, compression, remote access, and rechunking data for faster access are possible with nccopy. Compiling and linking programs that use netCDF C-based libraries is easier with nc-config.
CDL (Common Data form Language): a human-readable text representation of netCDF data.
The ncdump command-line utility converts netCDF data to human-readable text form.

NcML (netCDF Markup Language) is a dialect of XML for representing netCDF data, for virtual netCDF files, and for virtual aggregations.
From a CDL text file input, the ncgen command-line utility can generate a binary netCDF file, or a C, Fortran, or Java program.

ncdump and ncgen together
Used together, ncdump and ncgen can accomplish simple netCDF manipulations with little or no programming.
The nccopy command-line utility copies and optionally compresses and chunks netCDF data.

The nc-config command-line utility assists with the setting of compiler and linker flags for C, C++, and Fortran applications.
The netCDF library and utilities in versions 3.6.3 and later permit Unicode names for netCDF objects.
Special attributes for netCDF-4 data

Other NetCDF Utilities
Many other useful netCDF utilities developed by third parties are available, for example NCL, NCO, and CDO packages. The Java ToolsUI utility is described in the netCDF Java session.
