Do you get asterisks when you type in password in Linux?

There’s no terminal mode for printing asterisks because it would be a very specialized feature, useful only when entering passwords.
When to use an asterisk instead of a string?

Why is the asterisk not working in grep?
A grep command with an unquoted pattern that works now may stop working when you have different files or when you run it from a different place. Quote your regular expression and the problem goes away. Then the grep command treats * as a quantifier.
