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": "/"
}
