@jsjson/jsonhead v0.5.0

JsonHead

Output the first part of JSON files

jsonhead reads multiple JSON files and prints out the first 4 nodes of each JSON to the stdout, with the file name headers. When a single JSON file is given, the file name header is never printed. 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/jsonhead

Running the Script

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

jsonhead -n2 json-file1 json-file2 ...

jsonhead print the first 4 nodes/elements of each JSONFILE to standard output with the file name headers. The -n or --nodes argument sets the number of nodes or elements of JSON to print out instead of 4. The flag, -q or --quiet, prevents the file name headers from being printed.

When no json file is given, it reads from the stdin (until the EOF signal).

For complete usage info, including examples, try:

jsonhead -h
