How to manage and backup files on Kirin OS?

Kirin operating system is a Linux-based operating system widely used in the Chinese government and education fields. File management and backup on Kirin operating system is an important task, which can help us better manage and maintain important files and data. This article will introduce you to how to perform file management and backup on Kirin OS, with code examples.

1. File Management

1. Create a folder:

In the Kirin operating system, we can use the mkdir command to create a folder. For example, if we want to create a folder called "documents" in the current directory, we can run the following command:

mkdir documents

2. Move the folder:

if We want to move a folder to another location, we can use the mv command. For example, if we want to move the "documents" folder to another folder "backup", we can run the following command:

mv documents backup/

3. Copy the folder:

To copy a folder, we can use the cp command. For example, if we want to copy the "documents" folder to the "backup" folder, we can run the following command:

cp -r documents backup/

2. File backup

1. Manual backup:

On Kirin operating system, we can use the cp command to manually back up files. For example, if we want to back up a file named "example.txt" to the "backup" folder, we can run the following command:

cp example.txt backup/

2. Automatic backup:

In order to achieve automatic backup, we can write a simple Shell script. The following is a sample script that will automatically back up the files in the specified folder to another folder every day:

#!/bin/bash

# 设置源文件夹和目标文件夹
source_folder="/home/user/documents"
backup_folder="/home/user/backup"

# 获取当前日期和时间
date=$(date +%Y-%m-%d)
time=$(date +%H:%M:%S)

# 创建备份文件夹
backup_folder_name="$date-$time"
mkdir "$backup_folder/$backup_folder_name"

# 备份文件夹中的文件到新建的备份文件夹中
cp -r "$source_folder" "$backup_folder/$backup_folder_name"

# 输出备份完成的信息
echo "备份完成！备份文件创建于 $backup_folder_name"

In the above sample code, we first set the paths of the source and target folders . We then use the date command to get the current date and time and use it as the name of the backup folder. Next, we created a new backup folder via the mkdir command. Finally, we use the cp command to copy the files from the source folder to the new backup folder.

In order to achieve automatic backup, we can save the above script as a file named "backup.sh" and use the following command to add a scheduled task in the system's crontab:

crontab -e

Then , add the following line to the opened crontab file:

0 0 * * * /bin/bash /path/to/backup.sh

The above command indicates that the execution of the backup script is triggered at 0:00 midnight every day. You can adjust the triggering time of scheduled tasks according to your needs.

The above is a brief introduction and sample code for file management and backup on Kirin operating system. With these methods, you can better manage and protect your files and data. I wish you a happy work and study on Kirin OS!
