How to perform system automation scripts and task management on Kirin operating system?

Kirin operating system is a Linux-based operating system, which has the characteristics of high stability and security. On Kirin operating system, we can improve the efficiency and stability of the system by writing automated scripts and tasks.

1. Writing and executing Shell scripts
Shell script is a scripting language used to write and execute commands. By writing Shell scripts, we can automatically complete a series of complex operations on the Kirin operating system.

1. Create a Shell script
   On Kirin operating system, you can use a text editor (such as vi or nano) to create a new file. The file name ends with .sh, indicating that the file is Shell script. For example, we create a Shell script file named test.sh.

vi test.sh

2. Writing Shell Script
   In the test.sh file, we can write some commands to automate the system. For example, we can use the following code to output "Hello World!" in the terminal.

#!/bin/bash
echo "Hello World!"

3. Execute Shell script
   After saving and exiting the test.sh file, we can use the following command to execute the Shell script.

chmod +x test.sh
./test.sh

In this way, the terminal will output "Hello World!".

2. Management of scheduled tasks
In addition to automating one-time tasks through Shell scripts, we can also use scheduled tasks to perform certain tasks regularly.

1. Add scheduled tasks
   On the Kirin operating system, you can use the crontab command to add scheduled tasks. For example, we can use the following command to add a task that is executed every morning at 8 am.

crontab -e

In the open text editor, we can add the following content.

0 8 * * * /path/to/your/script.sh

/path/to/your/script.sh here is the path of the Shell script you need to execute.

2. View the scheduled task list
   If you want to view the currently added scheduled task list, you can use the following command.

crontab -l

In this way, the system will display the list of currently added scheduled tasks.

3. Use of automation tool Ansible
In addition to using shell scripts and scheduled tasks to manage the system, we can also use the automation tool Ansible to manage system configuration and tasks.

1. Installing Ansible
   First, we need to install Ansible on the Kirin operating system. Ansible can be installed using the following commands.

sudo apt-get update
sudo apt-get install ansible

2. Writing Ansible playbook
   In Ansible, we use playbook files to write automation scripts for configurations and tasks. You can use a text editor to create a new playbook file with a file name ending in .yml.

For example, we create a playbook file named test.yml.

---
- name: Test Playbook
  hosts: all
  tasks:
    - name: Print Hello World
      ansible.builtin.debug:
        msg: "Hello World!"

3. Execute Ansible playbook
   After saving and exiting the test.yml file, we can use the following command to execute Ansible playbook.

ansible-playbook test.yml

In this way, Ansible will execute the tasks defined in test.yml on the Kirin operating system and output "Hello World!".

Summary:
This article introduces how to perform system automation scripts and task management on the Kirin operating system. By writing Shell scripts, using scheduled tasks, and using the Ansible tool, we can realize automated system configuration and regular execution of tasks on the Kirin operating system. These methods can help improve the efficiency and stability of the system and reduce the workload of manual operations.
