Find free disk space in python on OS/X

Question

I'm looking for the number of free bytes on my HD, but have trouble doing so on python.

I've tried the following:

import os

stat = os.statvfs(path)
print stat.f_bsize * stat.f_bavail

But, on OS/X it gives me a 17529020874752 bytes, which is about about 1.6 TB, which would be very nice, but unfortunately not really true.

What's the best way to get to this figure?

Answer 1

Try using f_frsize instead of f_bsize.

>>> s = os.statvfs('/')
>>> (s.f_bavail * s.f_frsize) / 1024
23836592L
>>> os.system('df -k /')
Filesystem   1024-blocks     Used Available Capacity  Mounted on
/dev/disk0s2   116884912 92792320  23836592    80%    /
