Thread: How can this clear the screen?

Code:

printf("\e[H\e[2J");

I'm amazed

Can someone explain how can this clear the screen in details please?

Cursor Home

Code:

\e[{ROW};{COLUMN}H

\e[H

Sets the cursor position where subsequent text will begin. If no row/column parameters are provided (ie. \e[H), the cursor will move to the home position, at the upper left of the screen.


Erase Screen

Code:

\e[2J

Erases the screen with the background colour and moves the cursor to home.

I found that here.
