jsonpath - use JSON::Path to cut out selected portions of JSON objects

version 0.005

jsonpath [--verbose] -o json_path_1 [-o json_path_2 ...] [file ...]

jsonpath(1) cuts out selected portions of each JSON record and writes them to standard output. Fields are selected using JSON::Path expressions, which are a Perl-centric variant of JSONPath. Multiple fields may be specified, one per -o flag.
Output fields are named col#, where the # is the numeric position of the corresponding JSON::Path expression on the command line. The first column is col0. jmap(1) may be used to give each output field a more useful name.
