=head1 NAME
jcut - cut out selected portions of each JSON object in a file
=head1 SYNOPSIS
jcut -o field_1 [-o field_2 ...] [--verbose] [file ...]
=head1 DESCRIPTION
jcut(1) cuts out selected portions of each JSON record and writes them
to standard output. Multiple output fields may be specified, one per
-o flag.
=head1 SEE ALSO
You may read this utility's implementation in its entirety at
perldoc -m jcut
L<App::PipeFilter::JsonCut> implements this utility, including the
behavior of the -o flag.
The jsonpath(1) utility performs a similar function, but output fields
are specified by JSON::Path expressions instead of simple field names.
jsonpath(1) can therefore extract data from more complex JSON objects.
L<App::PipeFilter> has top-level documentation including a table of
contents for all the libraries and utilities included in the project.
=head1 PRO TIPS
JSON is relatively verbose compared to the whitespace-separated
formats that UNIX tools usually deal with. It's often beneficial to
jcut(1) the fields you need early in a pipeline chain and discard any
extraneous data.
