running a ping command as a node child_process and streaming its stdout for parsing

[Bernard Brault]

I am running a linux ping command as a child process using the node.js code below.

The ping command has to be continuous and normally displays the ping result every second when running in a console.

The last line of code simply pipes the output to the console as if the command had been issued on a console.

I need to parse the ping results as they come in in node.js.

Possible Solution : I think that this can possibly be done by creating a duplex stream, piping the "ping output" to the duplex stream and reading  on an "available" event.

I cannot get the above working! The first problem I run into is the lack of documentation on creating an instance for a duplex stream.

var exec = require('child_process').exec,

    child;

child = exec('ping  192.168.1.82',

    function (error, stdout, stderr) {

        console.log('stdout: ' + stdout);

        console.log('stderr: ' + stderr);

        if (error !== null) {

            console.log('exec error: ' + error);

        }

    });

child.stdout.pipe(process.stdout);

FWIW you can do ping in node without a child process: https://npmjs.org/package/net-ping
