title: Error using ncdump - NetCDF4 Python
body: <p>I am using python to read a netcdf dataset. I have installed netcdf and I am trying to read the data by typing, 
  ncdump("sample.nc",header_only=0). And I get the below error:
  /bin/sh: 1: ncdump.exe: not found.</p>
  
  <p>sample.nc is a netcdf file created using the following code:</p>
  
  <pre><code>from netCDF4 import Dataset    
  import numpy as np
  
  sfile = Dataset('sample.nc',mode='w', format='NETCDF4') 
  </code></pre>
  
  <p>Can anyone help me understand this error. I am quite new to this concept.
  Thanks</p>
