"Late claims" Linux one more-fourth rounds per day

Hello everyone, I am still your old friend at the end of the claim, a day more come, today we update is the Linux directory structure characteristics;

1. What are the Linux directory structure features?

Absolute path: A more precise display path

[Email protected] ~]# Cd/data

Relative paths: Paths that do not start from the root, more quickly, relative paths are relative to the current directory;

[email protected]/]# cat Data/test.txtoldgirl[[email protected]/]#

Devices that are mounted in 2.Linux

Each device (disk, partition, disc) in Linux must have a portal to use (the device under Linux must be mounted before it can be used)

A: Mount = = = To open an entrance to the device

B: Entry of the device = = = mount point = = = Directory--/mnt

3. Display disk usage

[Email protected]/]# #显示磁盘的使用情况 [[email protected]/]# cd[[email protected] ~]# df-hfilesystem Size used Avail use% Mounted On/dev/sda3 8.8G 1.5G 7.0G 18%/tmpfs 491M 0 491M 0%/dev/shm/dev/sda1 190M 35M 146 M 19%/boot/dev/sr0 3.7G 3.7G 0 100%/mnt[[email protected] ~]#

4.Linux below each disk partition

Can be arbitrarily mounted on the Linux directory
