Save this on your PATH. Read the first arg as the file or read stdin. When piping to it, /dev/stdin will look like a file and get and EOF when it's done... assuming your JSON doesn't overrun the memory, it should work.

#!/usr/bin/env node
var args = process.argv.splice( /node$/.test(process.argv[0]) ? 2 : 1 );
console.log(
    JSON.stringify(
        JSON.parse(
            require('fs') .readFileSync(
                args.length > 0 ? args[0] : "/dev/stdin"
            )
        ), null, 4)
);
