Hi,

How can I know if a certain node has the primary or replica shard?  
I'm doing tests with the forced awareness settings and need to know if it  
works.

Thanks

Try this:

% curl -s [download.elasticsearch.org/es2unix/es](http://download.elasticsearch.org/es2unix/es) \>es; chmod +x es  
% ./es shards

The output is easier to parse visually than json. From  
[GitHub - elastic/es2unix: Command-line ES](https://github.com/elasticsearch/es2unix).
