Cursor Controls Note these are case sensitive *are obtained by pressing Esc twice *[nA Move the cursor up n lines *[nB Move the cursor down n lines *[nC Move cursor n lines to the right *[nD Move cursor left n lines *[y;xH sets the cursor position *[2J Clear screen *[K clears the contents from the cursor to the end of the line *[s save cursor position *[u restore cursor position and cursor control 2 *[y;xf sets the cursor position and is now rarely used *[nL Insert n lines before the cursor line NANSI *[nM Delete n lines including the cursor line NANSI *[n@ Insert n blank characters at the cursor NANSI *[nP delete n characters including cursor position NANSI The so-called animation effect means that when the next character is displayed, the time is slower than the previous character. That is to use control characters to create a delay. Our approach is because netterm generally only has 24 lines. Save the coordinate position first, then jump the cursor to line 25 or 50, which we cannot see, and then delete a few hundred The action of a blank line or deleting hundreds of blank characters achieves a delay effect and then restores the cursor position. For example, the method between 1 and 5 above is 1*[s*[25;0f*[500M*[u5 ^ ^^ ^^ ^^ ^ Showing 5 Get the saved coordinate position In line 25, you can delete 500 lines by changing it to *[500@. Jump to the 0th position of line 25 and change the cursor to *[50;0f, which will have the same effect. Save the current coordinate position Show first 1 wWWWw Carry the lost dream and enjoy the escort of lovers in the rain @ Y The chill after the rain was just as strong yesterday The lonely and confused wind, the feelings are still not frozen Let the tender memories of yesterday dance in your heart E mail GeminiII@163.net Modification: unknown modified this article on Jul 16 15:49:11 [FROM: 10.64.5.133] Source: Sun and Moon Guanghua Station bbs.fudan.edu.cn [FROM: 10.64.5.40]
