macOS: difference between bfs and find with primaries -ls

[grylem]

Hi
echo file >file
find . -ls and ls -s
Display the same values for the number of file system blocks actually used by file - 8, but bfs -ls show - 4.
Regards.

Indeed, the traditional block size is 512 bytes, but bfs follows GNU find here and uses 1KiB blocks. GNU find's -ls will use 512B blocks if POSIXLY_CORRECT is set, even though -ls is not POSIX. bfs doesn't listen to POSIXLY_CORRECT about this, but it probably should.
