In this article, let us review the Linux filesystem structures and understand the meaning of individual high-level directories. 1. / – Root Every single file and directory starts from the root directory. Only root user has write privilege under this…

1. / – Root Every single file and directory starts from the root directory. Only root user has write privilege under this directory. Please note that /root is root user’s home directory, which is not same as /. 2. /bin – User Binaries Contains binary…

文件系统的运作与操作系统的文件数据有关.较新的操作系统的文件数据除了文件实际内容外,通常含有非常多的属性,例如Linux操作系统的文件权限(rwx)与文件属性(属主.属组.时间参数等).文件系统通常会将这两部分数据存放在不同的区块,权限与属性放置到inode 中,实际数据则放置到data block 中.还有一个超级区块(superblock) 会记录整个文件系统的整体信息,包括inode与block 的总量.使用量.剩余量等. 由于每个inode与block都有编号,而每个文件都会占用一个in…

16 down vote accepted The reason you can't find it is because, for the most part, it's not in the kernel -- it's in the userspace mount utility, which is in the util-linux package. If you don't give it a filesystem type, or if you give it a type of "…

5.1 机械硬盘 机械硬盘由多块盘片组成,它们都绕着主轴旋转.每块盘片上下方都有读写磁头悬浮在盘片上下方,它们与盘片的距离极小.在每次读写数据时盘片旋转,读写磁头被磁臂控制着不断的移动来读取其中的数据. 所有的盘片都是同时同步转动,所有的磁头也是同步移动. 磁盘在物理上划分了扇区.磁道和柱面.如果划分了分区,则分区是逻辑上柱面的分隔边界. 读写磁头在停止状态下,在盘片旋转时磁头扫过的一圈轨迹称为磁道,所有的磁道都是同心圆.从盘片外圈开始向内数,磁道号从0开始逐数增加. 每个磁道以512字节等分为…
