head -c, to print the specified number of bytes, is a GNU extension. Using dd for the same task should be somewhat more portable. Mac OS X does not have status=none, so redirect the status output away instead. Despite appearances, redirecting with the Bourne shell-ism `2>/dev/null` is fine on Windows since Windows executes with the internal lit shell runner, which translates `/dev/null` to a temporary file.
