Learn how to create Linux symbolic link files

Title: Easily learn how to create a link file in Linux

When using a Linux system, you often encounter situations where you need to create a link file. Linked files can help us access, manage and share files easily. This article will introduce you to how to create a link file in a Linux system, and provide specific code examples to help beginners quickly master this skill.

In Linux systems, there are two types of link files: hard links and symbolic links (soft links). A hard link refers to multiple files pointing to the same inode, that is, multiple files share the same disk space and cannot cross file systems. They can only link to files within the same file system. A symbolic link is a new file whose content is the path to the target file.

Below we will introduce how to establish hard links and symbolic links in Linux systems:

1. Establish hard links

1. Use in the terminal The ln command is used to create a hard link. The syntax is as follows:

ln 源文件名 目标文件名

2. For example, assuming there is a file test.txt in the current directory, we want to create a file named test.txt in the same directory. The hard link of test_link.txt, the command is as follows:

ln test.txt test_link.txt

3. Use the ls -li command to view the inode information of the file, and you can determine whether it is the same by the inode number File:

ls -li test.txt test_link.txt

2. Create a symbolic link

1. Use the ln -s command in the terminal to create a symbolic link. The syntax is as follows:

ln -s 源文件名 目标文件名

2. For example, assuming there is a file test.txt in the current directory, we want to create a symbolic link named test_symbolic_link.txt in the same directory. The command is as follows:

ln -s test.txt test_symbolic_link.txt

3. Use the ls -l command to view the link information of the file. The symbolic link will indicate the target file it points to with an arrow:

ls -l test.txt test_symbolic_link.txt

Through the above With these steps, we can easily create hard links and symbolic links in Linux systems to share and manage files. The method of establishing linked files is very common in practical applications. It can improve the readability and maintainability of files, while also saving disk space. It is an important skill in Linux systems.

We hope that the code examples provided in this article can help readers better understand how to create link files and can be used flexibly in practice. If you have any questions or comments, please leave a message for discussion, let us learn and make progress together!
