On the command line, du seems to return twice the numeric value returned by du -h.
Apparently, du -h resembles the actual file size, so what's the plain du value representing?
-h "Human-readable" output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte.
If -h is not given, the sizes are given in 512-byte blocks.
