CLS（清除）单行？ [英] CLS (clear) a single line?

问题描述

有没有办法 CLS 一行输出？我不相信 CLS 有任何开关，所以也许更好的问题是：

有没有办法

1. 保留所有以前的输出以便重复使用？
   
   或


2. 捕获当前显示的输出（像通过标记和复制一样）？

我只是试图通过提供实时反馈/信息来使我的脚本更加用户友好，而不是多条线略有变化。我可以想到这样做的唯一方法是这样：

  @echo off 
 goto Prep 
 
：Prep 
 SET count = 5 
 SET genericMessage =此窗口将关闭
 
 goto输出
 
：输出
 IF NOT％count％== -1（
 cls 
 IF％count％== 0（
 echo％genericMessage％now。
）ELSE（
 echo％genericMessage％in％count％seconds。
）
 SET / A count =％count％ -  1 
 ping localhost -n 2> nul 
 goto输出
）ELSE（
 exit 
）

但是，这个问题是 CLS 擦除所有输出，当我只想刷新

不幸的是，没有在Windows命令行控制台中重新定位光标的本机命令或实用程序。

您将需要第三方实用程序。 >

Aacini在DOSTips上发布了一个免费的CursorPos.exe实用程序。 CurorPos.exe源以十六进制数字形式给出。要使用源代码，您需要 HexToBin.bat编译器。

浏览这两个主题，你会发现很多实用程序可能对你有用。

Is there any way to CLS a single line of output? I don't believe there are any switches for CLS, so maybe a better question would be:

Is there any way to

1. retain all previous output for re-use?
   or
2. capture currently displayed output (like you can by marking and copying)?

I'm just trying to make my scripts a little more user-friendly by having real-time feedback / information, instead of multiple lines with slight changes. The only way I can think of doing this, though, is like this:

@echo off
goto Prep

:Prep
    SET count=5
    SET genericMessage=This window will close

    goto Output

:Output
    IF NOT %count% == -1 (
        cls
        IF %count% == 0 (
            echo %genericMessage% now.
        ) ELSE (
            echo %genericMessage% in %count% seconds.
        )
        SET /A count=%count% - 1
        ping localhost -n 2 >nul
        goto Output
    ) ELSE (
        exit
    )

So, you get this:

The problem with this, though, is that CLS erases all output, when I only want to refresh one line by erasing and re-outputting it.

Anyone have any ideas?

解决方案

Unfortunately, there is no native command or utility that repositions your cursor in a Windows command line console.

You will need a 3rd party utility.

Aacini posted a free CursorPos.exe utility on DOSTips. The CurorPos.exe "source" is given as Hex digits. To use the source you will need the HexToBin.bat "compiler".

Browse both threads and you will find a number of utilities you may find useful.
