How to perform multi-user management and permission settings on Kirin operating system?

Kirin operating system is an operating system based on the Linux kernel. It provides rich functions and flexible configuration options, allowing users to easily manage multiple users and assign appropriate permissions to each user. In this article, we will discuss how to perform multi-user management and permission settings on Kirin OS and provide some sample code.

1. Create user

On Kirin operating system, we can use the following command to create a new user:

sudo adduser username

In this command, username is the username of the new user you want to create. After executing this command, the system will prompt you to enter the new user's password and ask you to provide some other information, such as the user's full name.

2. Delete User

If you want to delete a user, you can use the following command:

sudo deluser username

This command will delete the user and its associated all files and directories. Note, before executing this command, please make sure that you have backed up the user's important files and that you have permission to perform this operation.

3. Change user password

To change the user's password, you can use the following command:

sudo passwd username

After executing this command, the system will prompt you to enter New password twice to confirm.

4. User Group

On Kirin operating system, we can use the /etc/group file to manage user groups. This file records information about all user groups in the system.

To add a user to a user group, you can use the following command:

sudo usermod -a -G groupname username

In this command, groupname is the name of the user group, username is the user's name. This command will add the user to the specified user group.

To remove a user from a user group, you can use the following command:

sudo gpasswd -d username groupname

In this command, username is the name of the user, groupname is the name of the user group. This command will remove the user from the specified user group.

5. Permission settings

On Kirin operating system, we can use the chmod command to set the permissions of files and directories. The following are some commonly used permission setting examples:

chmod u+rwx filename   # 给文件的所有者添加读、写和执行权限
chmod g+rw filename   # 给文件的所属组添加读和写权限
chmod o-r filename   # 禁止其他用户读取文件
chmod a+x script.sh   # 给所有用户添加执行脚本的权限
chmod 777 directory   # 给目录赋予最大的权限

In these examples, u represents the owner, g represents the group, and o represents For other users, a represents all users. represents add permission, - represents delete permission, r represents read permission, w represents write permission, x represents Execute permissions.

The above are some basic methods for multi-user management and permission settings on Kirin operating system. Through these methods, you can easily create, delete and manage users, assign appropriate permissions to users, and ensure the security and reliability of the system.

I hope this article can help you better understand how to perform multi-user management and permission settings on Kirin operating system.

Code Example:

The following is a simple Python script for creating users in batches and assigning permissions to them. Before running this script, make sure you have administrator rights.

import subprocess

users = ['user1', 'user2', 'user3']
permissions = ['--read', '--write', '--execute']

for user in users:
    # 创建用户
    subprocess.call(['sudo', 'adduser', user])
    
    # 为用户分配权限
    for permission in permissions:
        subprocess.call(['sudo', 'chmod', permission, f'/home/{user}/directory'])

In this example, we use the subprocess module to call system commands to create users and set permissions. Please modify the users and permissions lists according to your needs, as well as the directory path of the permission settings.

Please note that in order to ensure system security, please use administrator privileges with caution and make sure you understand the meaning and impact of these commands.

Hope this example can help you better understand how to perform multi-user management and permission settings through code. I wish you a happy use of Kirin OS!
