Linux Tips: Quickly Create Symbolic Link Files

Linux Tip Sharing: A simple way to create a link file

In the Linux system, link files are a very common function. File sharing and file sharing can be achieved by creating link files. Backup, file redirection and other functions. In our daily work, we often encounter situations where we need to create link files, so mastering an easy way to create link files is a very useful skill. This article will introduce how to quickly create a link file in a Linux system and provide specific code examples.

The difference between soft links and hard links

In Linux systems, link files are divided into two types: soft links and hard links. A soft link is a special file whose content is the path name of the file it points to. It is similar to a shortcut in Windows systems. Soft links can span file systems and can link directories. A hard link is a link method that points to the file storage location. It does not generate a file copy, but directly points to the inode node of the file. Therefore, modifications to the original file will be directly reflected in all hard links.

How to create a soft link file

In the Linux system, use the ln -s command to quickly create a soft link file. The following is a specific example. Suppose you want to create a soft link file named link_file in the current folder, linking to the /path/to/original_file file:

ln -s /path/to/original_file link_file

In the above command, the -s option indicates creating a soft link file. After executing the above command, a soft link file named link_file will be generated in the current folder, pointing to the /path/to/original_file file.

How to create a hard link file

To create a hard link file, use the ln command in the Linux system. The following is a specific example. Suppose you want to create a hard link file named hard_link_file in the current folder and link to the /path/to/original_file file:

ln /path/to/original_file hard_link_file

After executing the above command, a hard link file named hard_link_file will be generated in the current folder, pointing to the /path/to/original_file file.

Notes

• When creating a soft link file, you need to ensure that the original file path exists and is entered correctly, otherwise the soft link file will point incorrectly.
• When creating a hard link file, please note that hard links can only be created within the same file system and cannot cross file systems.

Summary

In Linux systems, creating link files is a common operation that can improve the efficiency of file management. Through the method introduced in this article, you can quickly create soft link and hard link files in the Linux system and flexibly apply them in actual work. Mastering the method of creating link files is a basic skill for Linux system users. I hope the content of this article can help you better use the Linux system.
