Python to calculate disk usage 1000 times of the du
0
I follow an instruction to calculate the disk usage:
import os
def disk_usage(path):
"""Return the number of bytes used by a file/folder and any descendents."""
total = os.path.getsize(path) # account for direct usage
if os.path.isdir(path): # if this is a directory,
for filename in os.listdir(path): # then for each child:
childpath = os.path.join(path, filename) # compose full path to child
total += disk_usage(childpath) # add child's usage to total
print ('{0:<10}'.format(total), path) # descriptive output (optional)
return total # return the grand total
Run it and get:
disk_usage("/Users/me/Desktop/PubRepo")
117976604 /Users/me/Desktop/PubRepo
Out[117]: 117976604
However, when I utilize du
In [124]: !du -s /Users/me/Desktop/PubRepo
125900 /Users/me/Desktop/PubRepo
-s, --summarize
display only a total for each argument
In [1]: 117976604 / 125900
Out[1]: 937.0659571088165
The python's result is about 1000 times.
What's the problem it might be?

dureturns the number of units in kilobytes.os.getsize()returns in bytes.
