title: How to do an unpretty print on pretty JSON file in shell >> serial string JSON >> ES _bulk?
body: <p>In working with Elasticsearch on AWS EC2, I just hit an issue with bulk indexing.  The ES _bulk endpoint requires the files to be basically JSON serial strings with \n terminators on each string; and what I have built using various web APIs and file pre/processing is pretty JSON ie., easily human readable.</p>
  <p><strong>Is there a simple shell script method to get all the pretty JSON simply concatenated into strings</strong>, without loading up some Java libraries or whatever? I can add tokens to the basic file during pre-processing to tag the desired \n breaks if that helps parsing, but if anyone has a tip on the toolset I would be grateful. I have a feeling there are scripts out there and I know there are some libraries, but I have not found any simple command line tools to do the unpretty printing so far.</p>
