In Linux, you can use the chown command to modify the user to whom the folder belongs.

chown command, which can be considered as the abbreviation of "change owner", is mainly used to modify the owner (user) of a file (or directory).

The basic format of modifying the owner:

[root@localhost ~]# chown [-R] 所有者 文件或目录

• -R (note the capital letters) option means together with all files in the subdirectory , both change owners.

Example:

[root@localhost ~]# touch file
#由root用户创建file文件
[root@localhost ~]# ll file
-rw-r--r--. 1 root root 0 Apr 17 05:12 file
#文件的所有者是root，普通用户user对这个文件拥有只读权限
[root@localhost ~]# chown user file
#修改文件的所有者
[root@localhost ~]# ll file
-rw-r--r--. 1 user root 0 Apr 17 05:12 file
#所有者变成了user用户，这时user用户对这个文件就拥有了读、写权限

You can see that by modifying the owner of the file file, the user user changes from someone else's identity (only has read permissions to this file) Becomes the owner and has read and write permissions for this file.
