df

Wraps df -B 512 (Linux and Cygwin) or df -b (OS X) and produces pretty output.

Gives output for both real and virtual filesystems.

Installation

To install both module and commandline versions:

npm install df
npm install -g df

Usage

Command-line:

df-json

Module:

(function () {
  "use strict";

  var df = require('df')
    ;

  df(function (err, table) {
    if (err) {
      console.error(err.stack);
      return;
    }

    console.log(JSON.stringify(table, null, '  '));
  });
}());

Output:

[
  {
    "filesystem": "/dev/disk0s2",
    "blocks": 488555536,
    "used": 472631632,
    "available": 15411904,
    "percent": 97,
    "mountpoint": "/",
    "type": "ext4"            // Linux only
  }
