df-fixed

df

Get free disk space info from df -kP

Works on any Unix based system like macOS and Linux.

Created because all the other df wrappers are terrible. This one uses simple and explicit parsing. Uses execFile rather than exec. Ensures better platform portability by using the -P flag. Returns sizes in bytes instead of kilobytes and the capacity as a float.

Install

$ npm install --save @sindresorhus/df

Usage

const df = require('@sindresorhus/df');
 
df().then(list => {
    console.log(list);
    /*
    [{
        filesystem: '/dev/disk1',
        size: 499046809600,
        used: 443222245376,
        available: 55562420224,
        capacity: 0.89,
        mountpoint: '/'
    }, ...]
    */
});
 
df.fs('/dev/disk1').then(data => {
    console.log(data);
    /*
    {
        filesystem: '/dev/disk1',
        ...
    }
    */
});
 
df.file(__dirname).then(data => {
    console.log(data);
    /*
    {
        filesystem: '/dev/disk1',
        ...
    }
    */
});
