How to analyze the directory structure in Linux system? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

In Linux system, all files and directories are tree structure based on "/" node, which is very different from Windows.

Linux directory structure / root partition, only root users have write access to this directory.

/ etc configuration file

/ boot startup file

/ var can grow the directory. Logs, files, etc.

/ root administrator the home directory of all data root users.

/ tmp temporary files (about once every 15 days. )

/ usr unix software source / usr/src source code directory. / usr/local 's own software installation location.

/ bin command binary executable.

/ sbin system commands.

/ mnt mount directory.

/ dev device file. Everything is files, terminals, disks, etc. Keyboard, mouse, etc.

/ home normal user file storage location.

/ proc virtual directory. You can view the status of each process.

/ lib stores the library files of the system (dynamic library, static library. .a static library, .so dynamic library). Similar to .dll files.

Absolute path and relative path absolute path starts from /.

The relative path is based on. .. It started.

Create, delete copy file touch a.txt create a file

Mkdir test creates a directory

[root@local ~] # less / var/log/messagesless can be viewed from top to bottom. Enter, the spaces are the next page. Q exit view.

[root@local ~] # more / var/log/messagesmore can only be viewed by turning the page down.

[root@local ~] # cat / var/log/messagescat displays all the content at once.
