After some research online, thank you StackOverflow, I understood that this message meant that the tool xcode-select was already installed, so I only needed to update it.
The command to use to update Xcode is :
softwareupdate command [args ...]

To install all updates, you can run :
softwareupdate --install -a
If you want to update one element, you can get the name from the list command and run :
softwareupdate --install <product name>
