jsonly

jsonly is a command-line tool written in Go that filters URLs from input and only prints those that match the following criteria:

1. The URL must be a valid HTTP/HTTPS URL.
2. The URL must have a .js file extension.

Features

• Reads URLs from stdin.
• Filters only URLs that end with .js.
• Displays usage if no parameters or input are provided.

Usage

Basic Usage

jsonly < input_file

This command will read from the input_file, filter out any non-.js URLs, and print the matching ones to stdout.

Example

Given the following input (input.txt):

http://example.com/script.js
http://example.com/index.html
https://example.com/other.js
https://example.com/script.js

Running the tool like this:

cat input.txt | jsonly

Would output:

http://example.com/script.js
https://example.com/other.js
https://example.com/script.js

No Input Provided

If no input is provided (i.e., the program is run without a pipe or input_file), it will display the usage message and exit:

Usage: jsonly < input_file
