jq
"OPTION -h"
jq - commandline JSON processor [version 1.7]
Usage: /bin/jq [options] <jq filter> [file...]
/bin/jq [options] --args <jq filter> [strings...]
/bin/jq [options] --jsonargs <jq filter> [JSON_TEXTS...]
jq is a tool for processing JSON inputs, applying the given filter to
its JSON text inputs and producing the filter's results as JSON on
standard output.
The simplest filter is ., which copies jq's input to its output
unmodified except for formatting. For more advanced filters see
the jq(1) manpage ("man jq") and/or https://jqlang.github.io/jq/.
Example:
$ echo '{"foo": 0}' | jq .
{
"foo": 0
}
Command options:
-n, --null-input use `null` as the single input value;
-R, --raw-input read each line as string instead of JSON;
-s, --slurp read all inputs into an array and use it as
the single input value;
-c, --compact-output compact instead of pretty-printed output;
-r, --raw-output output strings without escapes and quotes;
--raw-output0 implies -r and output NUL after each output;
-j, --join-output implies -r and output without newline after
each output;
-a, --ascii-output output strings by only ASCII characters
using escape sequences;
-S, --sort-keys sort keys of each object on output;
-C, --color-output colorize JSON output;
-M, --monochrome-output disable colored output;
--tab use tabs for indentation;
--indent n use n spaces for indentation (max 7 spaces);
--unbuffered flush output stream after each output;
--stream parse the input value in streaming fashion;
--stream-errors implies --stream and report parse error as
an array;
--seq parse input/output as application/json-seq;
-f, --from-file file load filter from the file;
-L directory search modules from the directory;
--arg name value set $name to the string value;
--argjson name value set $name to the JSON value;
--slurpfile name file set $name to an array of JSON values read
from the file;
--rawfile name file set $name to string contents of file;
--args consume remaining arguments as positional
string values;
--jsonargs consume remaining arguments as positional
JSON values;
-e, --exit-status set exit status code based on the output;
-V, --version show the version;
--build-configuration show jq's build configuration;
-h, --help show the help;
-- terminates argument processing;
Named arguments are also available as $ARGS.named[], while
positional arguments are available as $ARGS.positional[].

schema
JSON Schema Validation CLI
positional arguments:
schema the path to a JSON Schema to validate with (i.e.
schema.json)
options:
-h, --help show this help message and exit
-i INSTANCES, --instance INSTANCES
a path to a JSON instance (i.e. filename.json) to
validate (may be specified multiple times). If no
instances are provided via this option, one will be
expected on standard input.
-F ERROR_FORMAT, --error-format ERROR_FORMAT
the format to use for each validation error message,
specified in a form suitable for str.format. This
string will be passed one formatted object named
'error' for each ValidationError. Only provide this
option when using --output=plain, which is the
default. If this argument is unprovided and
--output=plain is used, a simple default
representation will be used.
-o {plain,pretty}, --output {plain,pretty}
an output format to use. 'plain' (default) will
produce minimal text with one line for each error,
while 'pretty' will produce more detailed human-
readable output on multiple lines.
-V VALIDATOR, --validator VALIDATOR
the fully qualified object name of a validator to use,
or, for validators that are registered with
jsonschema, simply the name of the class.
--base-uri BASE_URI a base URI to assign to the provided schema, even if
it does not declare one (via e.g. $id). This option
can be used if you wish to resolve relative references
to a particular URI (or local path)
--version show program's version number and exit
