Linux File System Structure

/Boot directory:

The storage location of the kernel files and System Bootstrap files stores the current kernel of the system [generally MB]

For example, the configuration file of the grub boot file

/Etc directory:

This directory must be backed up when backing up the system.

For example, a file that the system administrator often needs to modify determines the configuration file for system behavior.

/Bin,/usr/bin directory:

Store frequently-used commands of users [All users can use]

Such as ls and cp

/Sbin,/usr/sbin directory:

Command Used To save system maintenance [common users are unavailable and only root users are available]

For example, fdisk: Partition

Mkfs: Format

/Lib directory:

Saves the library files required for running the system. When installing the program, the Library is automatically copied here.

For example, a static library file suffixed with. a in C Language

Dynamic library file with. so Extension

/Dev directory:

Store Device Files

For example:/dev/cdrom

/Dev/hda

/Dev/sdb

/Var directory:

Saves frequently changed files and data during system operation

For example, log file: log

Email file: mail

Offline files and scheduled tasks

/Mut directory:

For the convenience of installing the temporary file system, the devices are usually mounted to the mut directory.

For example, a CD: mut/cdrom

USB flash disk: mut/sdb2

/Proc directory:

System memory/CPU ing, stores the current memory image, virtual file system, not stored in the hard disk

For example, view the memory size: more/proc/meminfo

View CPU: more/proc/cpuinfo

After the directory is deleted and restarted, it will be mapped again.

/Tmp directory:

Used to save temporary files generated when the system is running. special permissions: Stick bit t

For example, temporary data during program running

/Usr directory:

It is the largest in the system to store user-related information.

Saves almost all commands, libraries, and manual pages. Similar to the C: \ Windows directory in windows, you are used to installing software in the/usr/local directory.

/Home directory:

In the system, the Home Directory of a common user; cd returns its home directory by default

/Root directory:

The root directory of the Super User IN THE SYSTEM

/Lost + found

Stores system error check results. The directory is empty by default.

[Most of the others have no important functions, and many of them are empty !]

[When managing a file system,/home,/boot,/usr can be separated separately]
