jq is a command line tool and also a language for expressing transformations on JSON with concise one-liners. It is useful for processing the output of mongoexport or an elasticsearch query. The basic constructs are "filter expressions". Pipes (|) can be used to direct the output of one filter expression to another, and commas (,) can be used to concatenate the output of two filter expressions.
