Hi Chris,
Unfortunately, the nccopy version is currently not available from the
binary.
However, if you invoke ncdump with no arguments from the directory that
nccopy is in, the ncdump version will be printed on the last line of the
resulting usage message, and that will correspond to the nccopy version.
There will be a fix for nccopy in the upcoming 4.3.3 release so that the
library version will be printed at the end of a usage message for nccopy,
as it already is for the ncdump and ncgen utilities.
If you don't have the associated ncdump utilities, you can still bracket
the versions of nccopy by what usage message gets printed when nccopy is
invoked with no arguments, because later versions supported more arguments.
Here's usage messages from various versions:
