3.32 Operator Version

Availability: All operators
Short options: ‘-r
Long options: ‘--revision’, ‘--version’, or ‘--vrs
All operators can be told to print their version information, library version, copyright notice, and compile-time configuration with the ‘-r’ switch, or its long-option equivalent ‘revision’. The ‘--version’ or ‘--vrs’ switches print the operator version information only. 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., 3.9.5. Using ‘-r’ on, say, ncks, produces something like ‘NCO netCDF Operators version "3.9.5" last modified 2008/05/11 built May 12 2008 on neige by zender Copyright (C) 1995--2008 Charlie Zender ncks version 20090918’. This tells you that ncks contains all patches up to version 3.9.5, which dates from May 11, 2008.
