问一个有关fdisk命令的问题
我想问下有关于fdisk命令中的一个选项(-a)的问题,书上说它的作用是:引导标志开关.这是什么意思呢?我找了很多资料都不知它是什么意思.恳请某位高人指点一下. Linux的fdisk有这个参数选项吗？哪本书上说的？ ???在男人里看不到该选项:L 没错,是有这个选项,另外我想对二楼的指正一个错误.在linux中参数就是参数,选项就是选项.这是两个不同的概念。不能混在一起. 不还意思，我现在使用的和以前使用的fdisk在线帮助里Options全都都没有这个－a，所以请你把出处的链接挂上。

以下是man fdisk：
FDISK(8) Linux Programmer's Manual FDISK(8)
NAME
fdisk - Partition table manipulator for Linux
SYNOPSIS
fdisk [-u] [-b sectorsize] [-C cyls] [-H heads] [-S sects] device
fdisk -l [-u] [device ...]
fdisk -s partition ...
fdisk -v
...
OPTIONS
-b sectorsize
Specify the sector size of the disk. Valid values are 512, 1024,
or 2048. (Recent kernels know the sector size. Use this only on
old kernels or to override the kernel's ideas.)
-C cyls
Specify the number of cylinders of the disk. I have no idea why
anybody would want to do so.
-H heads
Specify the number of heads of the disk. (Not the physical num-
ber, of course, but the number used for partition tables.) Rea-
sonable values are 255 and 16.
-S sects
Specify the number of sectors per track of the disk. (Not the
physical number, of course, but the number used for partition
tables.) A reasonable value is 63.
-l List the partition tables for the specified devices and then
exit. If no devices are given, those mentioned in /proc/parti-
tions (if that exists) are used.
-u When listing partition tables, give sizes in sectors instead of
cylinders.
-s partition
The size of the partition (in blocks) is printed on the standard
output.
-v Print version number of fdisk program and exit.
