Delete the Entire Line
If you’ve just typed a long string of commands that you don’t need to enter anymore, delete the entire line by using: CTRL+U,K. That is not easy. CTRL+U deletes whatever is to the left of the cursor and CTRL+K deletes what is to the right. If you are at the end of command, CTRL+U will do. Especially if you start typing password and you make a mistake. Alternatively, you can use CTRL+C, which discards the current typed command, and gives you a new line.
CTRL+L will clear the screen.
