Clearing output of a terminal program in Linux C


There're several ways to delete the DDDDDDDDDDDDDD

  1. Print backspace several times
printf("\b");
  1. Print carriage-return and then print something to override the original line
printf("\r");
  1. If you are in a newline. You may use terminal commands to move your cursor

such as printf("\033[8;5Hhello"); // Move to (8, 5) and output hello

Other commands:

printf("\033[XA"); // Move up X lines;printf("\033[XB"); // Move down X lines;printf("\033[XC"); // Move right X column;printf("\033[XD"); // Move left X column;printf("\033[2J"); // Clear screen...
  1. Don't forget ncurses

It is the best ways to control the exact layout and format in a terminal


If you are using X-Term compatibles (Gnome Terminal included), then print the following

printf("\033[2J");

or

cout << "\033[2J";

where \033 is the escape character in ASCII and [2J is the specific action (clear).


I tried answering for what is best expected here.

printf("AAAAAAAAAAAAAA");printf("BBBBBBBBBBBBBB");printf("CCCCCCCCCCCCCC");//printf("DDDDDDDDDDDDDD");

comment the last line or delete if you dont want to display in terminal. printf("xxxx") is the statement used for printing output in terminal.
