SuperUser阅读器Jay想知道为什么默认的Windows Command Prompt输出缓冲区大小如此之大：
I have been using the Command Prompt in Windows for a while now and just realized that there are several pages worth of empty lines below the text entry prompt. Why is that?
我已经在Windows中使用命令提示符已有一段时间了，只是意识到在文本输入提示下有几页空白行。 这是为什么？
Why is the default Windows Command Prompt output buffer size so large? Can its size be altered?
为什么默认的Windows命令提示符输出缓冲区大小如此之大？ 可以改变尺寸吗？
答案 (The Answer)
SuperUser contributors Steven and miltonb have the answer for us. First up, Steven:
超级用户贡献者Steven和Miltonb为我们提供了答案。 首先，史蒂文：
The “empty lines” are the rows of screen buffer that have not been filled with output yet. To change the screen buffer size from the default of 300 lines (Microsoft’s chosen default), perform the following steps:
“空行”是屏幕缓冲区中尚未填充输出的行。 要将屏幕缓冲区大小从默认的300行(Microsoft选择的默认值)更改，请执行以下步骤：
- Open the Windows Command Prompt 打开Windows命令提示符
- Right-click on the application’s icon in the upper left corner of the window右键单击窗口左上角的应用程序图标
Click on Properties in the drop down menu
在下拉菜单中单击属性
Select the Layout Tab
选择布局选项卡
Set the Screen Buffer Size (Height Listing) to 20
将屏幕缓冲区大小(列表高度)设置为20
Click OK
点击确定
Note: I recommend reverting the buffer size to something larger since 20 lines is not much in the way of displayed output.
注意：我建议将缓冲区大小恢复为更大的大小，因为20行显示的输出不会太多。
Followed by the answer from miltonb:
随后是miltonb的回答：
I know that this is not the “why” with regard to your question, but if you want to change the screen buffer size from within a Command Prompt window (or batch file), you can make use of the mode command (mode columns, lines). I regularly use this from within the command prompt:
我知道这不是问题的“原因”，但是如果您想在命令提示符窗口(或批处理文件)中更改屏幕缓冲区的大小，则可以使用mode命令(mode列，行)。 我经常在命令提示符下使用它：
- mode 200, 300 模式200、300
