When installing Docker, I didn’t understand the paragraph “Installing Bash Completion Scripts” in the document. What should I do?

This is just a smart prompt plug-in for installing commands. Its function is to press tab to complete the container id, container name and some parameters after entering docker.

If you don’t need it, you can not install it.
