    If I am understanding correctly you want to redirect your output to stdout?

    Put your cql command in a file. My files is called select.cql and contents are:

    select id from wiki.solr limit 100;
    

    Then issue the following and you get it to stdout:

    cqlsh < select.cql
    

    I hope this helps. From there on you can pipe it and add commas, remove headers etc.
