diskspace

Fork of scriptingosx/diskspace

Returns available disk space

With the various APFS features the value for free disk space returned from tools such as du or df will not be accurate. This tool uses system functions to get various measures of available disk space.

The 'Important' value matches the free disk space value shown in Finder.

You can get the details from Apple's documentation:
