In reply to Stranger.

There can be two reasons (that I can think of):

One is Rounding:

The sizes are quite quickly rounded up (a few k over the mark is enough).

10M File_A – might be 9.2M
14M Dir_A – might be 13.2M
23M total – because that adds up to 22.4, which again is rounded up.

But I think that can’t explain it fully.

It might be because you simplified your example and there are more of these files/directories of a few k which all get rounded up to 1M.

– The functioning of *
Another way is that there are files/directories starting with . in your main directory.
These are not shown in the list when you use *, but they are calculated in the total of the main directory.

A kilobyte is 1000 bytes, always has (referring to the -k switch part). A kilo is always a unit of 1000 (e.g. a kilometer is also 1000 meters). A kibibyte is 1024 bytes. I know that Americans aren’t used to the metric system, but please, get it right when you do use it. I see these mistakes happen in blogs like these all the time…
