format命令

由于它的破坏性极大，使用时一定要小心!
两个用途，即格式化硬盘和重新对硬盘分区.
1)格式化硬盘
最好进入单用户模式
#format
系统会显示所有的硬盘并让我们选择要操作硬盘

使用命令newfs来为每一个分区创建文件系统:
newfs/dev/rdsk/c?t?d?s?
硬盘包含启动分区(根分区)，我们需要手动安装启动模块
#rebootcdrom-s(从光盘启动，并进入单用户模式)
#mount/dev/dsk/c0t1d0s0/mnt (将系统根分区挂接到mnt目录下)
#cp/ufsboot/mnt
#installboot/lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0(安装启动模块)
#umount/mnt(卸下挂接)
#reboot(重启动)

2)重新分区
format命令也可以对硬盘进行重新分区。重新分区后，受影响分区上的所有文件将被清除
要对该分区表命名，SAVE退出format命令。分区结束后，我们要用newfs命令为改变的分区创建文件系统
