You can install multiple packages on one line.
Apt has various options to reduce/eliminate interactivity, of course using them comes at some risk
--trivial-only
This will make the command only succeed if it would have run without a prompt, otherwise it fails.
--assume-yes (or -y)
this will make the command assume yes to most prompts but it will abort on some of the scarier ones (it still carries a risk of damage though)
--force-yes
should be pretty self explanatory.
