1)mkfs的使用;
使用方法:
[root@localhost beinan]# mkfs -t 文件系统 存储设备
注:
这里的文件系统是要指定的,比如 ext3 ;reiserfs ;ext2 ;fat32 ;msdos 等... ...
设备比如是一个硬盘的分区,软盘,光驱等.. ...
在格式化分区之前,您得懂得如何查看硬盘分区情况,并有针对性的格式化;比如用 fdisk -l 来查看;
比如我想格式化一个移动U盘中的一个分区;全景应该是:
[root@localhost beinan]# fdisk -l

Disk /dev/sda: 1035 MB, 1035730944 bytes
256 heads, 63 sectors/track, 125 cylinders
Units = cylinders of 16128 * 512 = 8257536 bytes

/dev/sda5 26 50 201568 83 Linux
/dev/sda6 51 76 200781 83 Linux
我们可以看到有sda这个设备,所以可以用 fdisk -l /dev/sda专门来显示他的分区情况;比如我想格式化 /dev/sda6 分区为 ext3文件系统,则为:
[root@localhost beinan]# mkfs -t ext3 /dev/sda6
