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 @sindresorhus/df

Usage

import {
	diskSpace,
	diskSpaceForFilesystem,
	diskSpaceForFilesystemOwningPath
} from '@sindresorhus/df';

console.log(await diskSpace());
/*
[
	{
		filesystem: '/dev/disk1',
		type: 'ext4',
		size: 499046809600,
		used: 443222245376,
		available: 55562420224,
		capacity: 0.89,
		mountpoint: '/'
	},
	…
]
*/

console.log(await diskSpaceForFilesystem('/dev/disk1'));
/*
{
	filesystem: '/dev/disk1',
	…
}
*/

console.log(await diskSpaceForFilesystemOwningPath('.'));
/*
{
	filesystem: '/dev/disk1',
	…
}
*/

• type - Type of the filesystem. (Not available on macOS)
• size - Total size in bytes.
• used - Used size in bytes.
• available - Available size in bytes.
• capacity - Capacity as a float from 0 to 1.
• mountpoint - Disk mount location.

path

Type: string

A path to a filesystem device file. Example: '/dev/disk1'.

diskSpaceForFilesystemOwningPath(path)
