To look at just the header information (also called the schema or metadata):
$ ncdump -h mslp.ncoutput
To look at header and coordinate information, but not the data:
$ ncdump -c mslp.ncoutput
To look at all the data in the file, in addition to the metadata:
$ ncdump mslp.ncoutput
To look at a subset of the data by specifying one or more variables:
$ ncdump -v lat,time mslp.ncoutput
To see times in human-readable form:
$ ncdump -t -v lat,time mslp.ncoutput
You can specify brief (-b) or full (-f) annotation, showing indices in either 1-based Fortran or 0-based C order. To look at data values briefly annotated with array indices, in Fortran order:
$ ncdump -b f mslp.ncoutput
To look at what kind of netCDF data is in the file (classic, 64-bit offset, netCDF-4, or netCDF-4 classic model):
$ ncdump -k mslp.nc
