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?

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.

Also note that this is a common switch in utilities that have confirmation prompts in their functionality. While it's convenient in the shell, the real purpose is for automating scripts.

I wouldn't go as far as calling-y"common". The feature is fairly common in system administration tools (of which apt-get is one) but the method varies. When in doubt, always refer to the man page for the command in question for what parameter to use and what effect it has.

One side effect of using-yis that it will skip downgrades, whereas if the user enteredy, it would perform the downgrades. So if you want-yto execute the same thing as a user enteringy, you also need to add--allow-downgrades.
