Glayvinz!

Gibibytes

I just discovered that the df -h command in Leopard (which gives information about disk use) lists sizes using binary prefixes:

Filesystem      Size   Used  Avail Capacity  Mounted on
/dev/disk0s2   233Gi  104Gi  129Gi    45%    /
devfs          107Ki  107Ki    0Bi   100%    /dev
fdesc          1.0Ki  1.0Ki    0Bi   100%    /dev
map -hosts       0Bi    0Bi    0Bi   100%    /net
map auto_home    0Bi    0Bi    0Bi   100%    /home
/dev/disk1s2   980Mi  848Mi  132Mi    87%    /Volumes/Hilbert

For example, it lists the available space on my main drive as 129Gi, which stands for 129 gibibytes. Yes, “gibi”, not “giga”. So delightfully pedantic and nerdy! I don’t think the Tiger version was like this.
