ncks -- netCDF Kitchen Sink version 3.1 (first public release)
Purpose:
ncks combines a generic netCDF printer (like ncdump),
extractor (like ncextr) and hyperslabber (the nccut specification) into
one command. ncks is intended to be a tool for the rapid analysis and
manipulation of netCDF datasets.
Example: Printed output looks something like....
T: type = float, attributes = 3, dimensions = 4, id = 35
T attribute 0: name = units, type = char, length = 6, value = Kelvin
T attribute 1: name = levels, type = char, length = 10, value = midpoints
T attribute 2: name = time_rep, type = char, length = 14, value = instantaneous
T dimension 0 is a coordinate: name = time, type = float, size = 1
T dimension 1 is a coordinate: name = lat, type = float, size = 64
T dimension 2 is a coordinate: name = lev, type = float, size = 18
T dimension 3 is a coordinate: name = lon, type = float, size = 128
T size is 1*64*18*128*sizeof(float) = 147456*4 = 589824 bytes

Requirements:
* netCDF (must be installed on your system)
Obtaining the source:
Anonymous FTP to ftp.cgd.ucar.edu. Look in the directory
pub/zender and grab the compressed tar file ncks-3.1.tar.gz
which contains the entire source tree.
Files:
ncks-3.1.tar.gz the entire source tree:
./ncks-3.1/README.ncks this file
./ncks-3.1/ncks.1 ncks man page
./ncks-3.1/ncks.c ncks source code
./ncks-3.1/ncks.h ncks include file
./ncks-3.1/ncks.nc sample input file to play around with
Installation:
The compressed tarfile ncks-3.1.tar.gz must be uncompressed (with GNU
gunzip) and then untarred (tar -xvf ncks-3.1.tar).
Install ncks.1 in your man/man1 directory (and view with "man
ncks"), or view it directory with "nroff -man ncks.1 | less".
To compile ncks.c, run the sample compile command below after editing it
to suit your system. The root of your netCDF installation source tree
should replace the $NETCDF_ROOT variable, e.g.,
"setenv NETCDF_ROOT /opt/netcdf2.3.2"
gcc -o ncks -I$NETCDF_ROOT/include ncks.c -L$NETCDF_ROOT/lib -lnetcdf
acc -o ncks -I$NETCDF_ROOT/include ncks.c -L$NETCDF_ROOT/lib -lnetcdf
cc -o ncks -I$NETCDF_ROOT/include ncks.c -L$NETCDF_ROOT/lib -lnetcdf
Good luck,
