NAME

jsonjoin

SYNOPSIS

jsonjoin OPTIONS JSON_FILENAME [JSON_FILENAME …]

DESCRIPTION

jsonjoin joins one or more JSON objects. By default the objects are each assigned to an attribute corresponding with their filenames minus the “.json” extension. If the object is read from standard input then “_” is used as it’s attribute name.

If you use the update or overwrite options you will create a merged object. The update option keeps the attribute value first encountered and overwrite takes the last attribute value encountered.

EXAMPLES

This is an example of take “my1.json” and “my2.json” render “my.json”

    jsonjoin my1.json my2.json >my.json

my.json would have two attributes, “my1” and “my2” each with their complete attributes.

Using the update option you can merge my1.json with any additional attribute values found in m2.json.

    jsonjoin -update my1.json my2.json >my.json

Using the overwrite option you can merge my1.json with my2.json accepted as replacement values.

    jsonjoin -overwrite my1.json my2.json >my.json
