I always see commands like this
apt-get -y install What is the -y tag for and what is the difference between apt-get install with and without the -y tag?
1 Answer
From the results of running man apt-get
-y, --yes, --assume-yes Automatic yes to prompts; assume "yes" as answer to all prompts and run non-interactively. If an undesirable situation, such as changing a held package, trying to install a unauthenticated package or removing an essential package occurs then apt-get will abort. Configuration Item: APT::Get::Assume-Yes. If you run an apt-get command without the -y option, you need to answer to all prompts that you get from that command interactively in order for the execution of the command to continue.
