Hm. Yeah... Maybe. Journaling add -in my experience- about 32MB. |

Yes |

But you're all missing rounding errors. If you do: |
28 |
|
29 |
du -hcs /path/to/some/dir |
30 |
|
31 |
You'll end up with a different result if you instead do: |
32 |
|
33 |
du -bcs /path/to/some/dir |
34 |
|
35 |
Real example: |
36 |
|
37 |
zoolook@melnitz ~ $ du -bcs Desktop/ |
38 |
1289720534 Desktop/ |
39 |
1289720534 total |
40 |
|
41 |
zoolook@melnitz ~ $ du -hcs Desktop/ |
42 |
1.3G Desktop/ |
43 |
1.3G total |
44 |
|
45 |
If you do the math, 1.3G is more or less 1395864372 bytes; ~110MB in |
46 |
diference and same tool. |
