Some time ago I wrote something like that for a script of mine:
"""Report disk usage.
Return a dictionary with total, used, available. Sizes are reported
in blocks of 1024 bytes."""
output = subprocess.Popen(
['/bin/df', '-B 1024', filesystem],
lines = output.split('\n')
fs, blocks_total, blocks_used, blocks_available, used, mount =
blocks_total = int(blocks_total)
blocks_used = int(blocks_used)
blocks_available = int(blocks_available)
I use from a cronjob in a script that monitors the disk usage and sends
me a mail if the disk gets too full.
The saddest aspect of life right now is that science gathers knowledge
faster than society gathers wisdom.
