Re: [nodejs] How to have childprocess.stdout printed without delay

[Matt]

Convince the command not to buffer. It is probably written such that if it thinks stdout is a tty it line-buffers, but if stdout is a pipe it block-buffers.

In perl you do this via "$|++". The app may have a command-line flag for it if you're lucky.

So I have something like:

function startWebApp(command, arguments) {
    var childProc = require("child_process").exec(command, arguments);
    childProc.stdout.pipe(process.stdout);
    childProc.on("exit", process.exit);
}

The output seems to be buffered and result seems to be delayed, it only printed after some interval compared to when I runs the "command" directly in bash.

Is there a way around this.

Thanks and Regards,
