You can use the attribute ..nvars attributes.

let num = ..nvars

The variable 'num' will store the number of variables (9 in your case) in the netCDF file opened. More details can be foundhere.

Sorry for the typing mistake, corrected question:

Suppose I have an .nc file with 9 variables in it ( say v1, v2, v3 . . . . v9 ).

How to getnumberof variables from any such .nc file (without counting manually from .nc) ? ( I want a command which gives 9 as answer in above example)
