3.28 Operator Version

Availability: All operators
Short options: `-r'
Long options: `--revision', `--version', or `--vrs'
All operators can be told to print their internal version number and copyright notice and then quit with the `-r' switch. The internal version number varies between operators, and indicates the most recent change to a particular operator's source code. This is useful in making sure you are working with the most recent operators. The version of NCO you are using might be, e.g., 1.2. However using `-r' on, say, ncks, will produce something like `NCO netCDF Operators version 1.2 Copyright (C) 1995--2000 Charlie Zender ncks version 1.30 (2000/07/31) "Bolivia"'. This tells you ncks contains all patches up to version 1.30, which dates from July 31, 2000.
