JsonCat

JSON file concatenator

jsoncat concatenates multiple JSON files into a single array and prints out the output to the stdout. When a single JSON file is given, it does not add a top-level array. When no JSON file is given, it reads JSON from the stdin.

Installation

First, install node.js (along with npm) if you haven't already done so.

npm install -g @jsjson/jsoncat

Running the Script

The NPM package installs an executable jsoncat in your PATH. Run the script as follows:

jsoncat -i4 json-file1 json-file2 ...

The -i or --indent argument sets the indentation level when printing out the JSON files.

Note that each json file should be a valid JSON. jsoncat concatenates the input json files, if more than one file is given, into a single top-level array. The merge flag, -m or --merges, merges the JSON files into the top-level array, if a given json file is a JSON array.

When no json file is given, it reads from the stdin (until the EOF signal). The "-" symbol can also be used for stdin. For example, the following command

jsoncat -i4 json-file1 - json-file2

concatenates json-file1, stdin, and json-file2.

For complete usage info, including examples, try:

jsoncat -h
