問題 (The Question)
SuperUser reader Jay wants to know why the default Windows Command Prompt output buffer size is so large:
SuperUser閱讀器Jay想知道為什么默認的Windows Command Prompt輸出緩沖區大小如此之大：
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?
我已經在Windows中使用命令提示符已有一段時間了，只是意識到在文本輸入提示下有幾頁空白行。 這是為什么？
Why is the default Windows Command Prompt output buffer size so large? Can its size be altered?
為什么默認的Windows命令提示符輸出緩沖區大小如此之大？ 可以改變尺寸嗎？
答案 (The Answer)
SuperUser contributors Steven and miltonb have the answer for us. First up, Steven:
超級用戶貢獻者Steven和Miltonb為我們提供了答案。 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”是屏幕緩沖區中尚未填充輸出的行。 要將屏幕緩沖區大小從默認的300行(Microsoft選擇的默認值)更改，請執行以下步驟：
- Open the Windows Command Prompt 打開Windows命令提示符
- Right-click on the application’s icon in the upper left corner of the window右鍵單擊窗口左上角的應用程序圖標
Click on Properties in the drop down menu
在下拉菜單中單擊屬性
Select the Layout Tab
選擇布局選項卡
Set the Screen Buffer Size (Height Listing) to 20
將屏幕緩沖區大小(列表高度)設置為20
Click OK
點擊確定
Note: I recommend reverting the buffer size to something larger since 20 lines is not much in the way of displayed output.
注意：我建議將緩沖區大小恢復為更大的大小，因為20行顯示的輸出不會太多。
Followed by the answer from miltonb:
隨后是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:
我知道這不是問題的“原因”，但是如果您想在命令提示符窗口(或批處理文件)中更改屏幕緩沖區的大小，則可以使用mode命令(mode列，行)。 我經常在命令提示符下使用它：
- mode 200, 300 模式200、300
