[netCDF #DYO-865983]: extract only data, no variable information

Hello,

Unfortunately there is not a flag to pass to ncdump which will extract only the 
data values and nothing else; ncdump generates (by default) cdl-formatted 
files, and lists of values are not properly formatted cdl.

You could get closer with some creative shell scripting, e.g.

    $ ncdump -v GroupDelaySig,GroupDelay GroupDelay_bS.nc | tail -n $(( 
$(ncdump -v GroupDelaySig,GroupDelay GroupDelay_bS.nc | wc -l)- $(ncdump -hv 
GroupDelaySig,GroupDelay GroupDelay_bS.nc | wc -l))) | grep -v '}'

This shell command computes the size of the metadata generated by ncdump, 
subtracts that from the total length of ncdump, and then extracts the final X 
lines from ncdump, where X contains the data for GroupDelaySig,GroupDelay.

I'm sorry there isn't a single flag you can pass to ncdump, but hopefully this 
will help.

have a great day,

-Ward
