How to scroll up the bottom of line to the top of the window in terminal

In vim and many other text editors, you can scroll up the end of the file to the top of your screen while showing the rest of the lines as blank. But in terminal, by default, the end of line is fixed to the end of the terminal window so your current line is always appearing at the very bottom of your screen. This is a little frustrating. I want to scroll up and down flexibly the command line to keep it at the center of my sight. How can I do that?

Thanks.
