Linux Shell Command Series (3)

One. Chown command

The "chown" command changes the owner of the file and the user group. Each file belongs to one user group and one user. In your directory, use "Ls-l" and you will see something like this.
[Email protected]:~# ls-l

Drwxr-xr-x 3 server root 4096 11:14 Binary
Drwxr-xr-x 2 Server server 4096 may 09:42 Desktop
Here, the directory binary belongs to the user "server", and the user group "root", and the Directory "Desktop" belongs to the user "server" and the user group "server"
The "chown" command is used to change the ownership of a file, so only the user and user groups that administer and provide the files are authorized.
[Email protected]:~# chown server:server Binary

Drwxr-xr-x 3 Server server 4096 may 11:14 Binary
Drwxr-xr-x 2 Server server 4096 may 09:42 Desktop
Note: The files given by "Chown" change the ownership of users and groups to new owners or existing users or groups of users.
