1. Function
The Linux/Unix operating system uses the chown command to change the owner of the specified file to the specified user or group.
Users can be usernames or user IDs; groups can be group names or group IDs.
Files are separated by spaces and support wildcards ( wildcards are a special sentence, mainly including asterisks (*) and question marks (?), which are used to vaguely search for files. When searching for a folder, you can use it to replace one or more A real character ; when you don’t know the real character or are too lazy to enter the full name, wildcards are often used instead of one or more real characters).
