我根据@arnep的想法做了一个函数:

echo|set /p="Hello World"

下面就是:

:SL (sameline)
echo|set /p=%1
exit /b

使用call:SL "Hello There" 我知道这没什么特别的，但我花了很长时间才想出来，所以我想我应该把它贴在这里。

你可以从gnuwin32 (coreutils包)中使用“tr”删除换行符

@echo off
set L=First line
echo %L% | tr -d "\r\n"
echo Second line
pause

顺便说一下，如果您正在编写大量脚本，gnuwin32是一个金矿。

使用:echo | set /p=或<NUL set /p=都可以抑制换行符。

然而，当编写更高级的脚本时，检查ERRORLEVEL变得很重要，因为设置set /p=而不指定变量名将把ERRORLEVEL设置为1，这可能是非常危险的。

一个更好的方法是使用一个虚拟变量名，就像这样: echo | set /p dummyName=Hello World

这将产生你想要的东西，没有任何偷偷摸摸的东西在后台，因为我必须找到艰难的方法，但这只适用于管道版本;<NUL set /p dummyName=Hello仍然会将ERRORLEVEL提升为1。

这里是另一个方法，它使用Powershell Write-Host，它有一个-NoNewLine参数，结合start /b，它从批处理中提供了相同的功能。

NoNewLines.cmd

@ECHO OFF
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 1 - ';Write-Host -NoNewLine 'Result 2 - ';Write-Host -NoNewLine 'Result 3 - '"
PAUSE

输出

Result 1 - Result 2 - Result 3 - Press any key to continue . . .

下面这个略有不同，并不完全像OP想要的那样工作，但很有趣，因为每个结果都覆盖了模拟计数器的前一个结果。

@ECHO OFF
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 1 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 2 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 3 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 4 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 5 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 6 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 7 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 8 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 9 - '"
PAUSE

使用set和/p参数可以不带换行符进行回显:

C:\> echo Hello World
Hello World

C:\> echo|set /p="Hello World"
Hello World
C:\>

简单的SET /P方法在不同的Windows版本之间有一些限制。

前导引号可能被删除 前导空白可能被剥离 Leading =导致语法错误。

jeb发布了一个聪明的解决方案，解决了输出文本没有换行的大部分问题，甚至有前导空格或=我已经改进了方法，以便它可以安全地打印任何有效的批处理字符串，没有新行，在任何版本的Windows XP开始。注意:writeInitialize方法包含一个字符串字面值，可能不能很好地发布到站点。包括一个注释，描述字符序列应该是什么。

:write和:writeVar方法经过优化，只有包含麻烦的前导字符的字符串才会使用我修改过的jeb的COPY方法来编写。不麻烦的字符串是使用更简单和更快的SET /P方法编写的。

@echo off

call :writeInitialize
call :write "=hello"

:write  Str
::
:: Write the literal string Str to stdout without a terminating
:: carriage return or line feed. Enclosing quotes are stripped.
::
:: This routine works by calling :writeVar
::
setlocal disableDelayedExpansion
set "str=%~1"
call :writeVar str
exit /b


:writeVar  StrVar
::
:: Writes the value of variable StrVar to stdout without a terminating
:: carriage return or line feed.
::
:: The routine relies on variables defined by :writeInitialize. If the
:: variables are not yet defined, then it calls :writeInitialize to
:: temporarily define them. Performance can be improved by explicitly
:: calling :writeInitialize once before the first call to :writeVar
::
