This code is a command executed in a Unix-like operating system, and it changes the ownership of files and directories recursively.

Specifically, "sudo" grants the current user temporary superuser privileges to run the command. "chown" is the command that changes the ownership of files and directories. The "-R" option indicates that the change should be applied recursively to all files and subdirectories within the specified directory.

Lastly, "ubuntu:ubuntu" specifies the new owner and group for the files and directories. In this case, both the owner and the group are set to "ubuntu".
