The difference between soft links and hard links:

Hard connections refer to connections made through index nodes. In Linux file systems, files stored in disk partitions, regardless of their type, are assigned a number called an Inode index.

In Linux, multiple file names pointing to the same inode exist. Generally, this connection is a hard connection. The purpose of hard links is to allow a file to have multiple valid pathnames, so that users can establish hard links to important pathnames.

File to prevent "accidental deletion" function. The reason for this is as described above, because there is more than one connection to the index node of this directory. Deleting only one connection does not affect the index node itself and other connections, only if the last one

After the connection is deleted, the data block of the file and the connection of the directory are released. In other words, the file is actually deleted.

Soft link files are somewhat similar to Windows shortcuts. It's actually a special kind of file. In symbolic links, a file is actually a text file that contains information about the location of another file.
