Cursor Movement

ANSI escape sequences allow you to move the cursor around the screen at will. This is more useful for full screen user interfaces generated by shell scripts, but can also be used in prompts. The movement escape sequences are as follows:

- Position the Cursor: \033[<L>;<C>H Or \033[<L>;<C>f puts the cursor at line L and column C. - Move the cursor up N lines: \033[<N>A - Move the cursor down N lines: \033[<N>B - Move the cursor forward N columns: \033[<N>C - Move the cursor backward N columns: \033[<N>D - Clear the screen, move to (0,0): \033[2J - Erase to end of line: \033[K - Save cursor position: \033[s - Restore cursor position: \033[u
