jscript:

如果它叫write.bat，你可以这样测试它:

call write.bat string & echo _Another_String_

如果你想使用powershell，但有cmd定义的变量，你可以使用:

set str=_My_StrinG_
powershell "Write-Host -NoNewline ""%str%""""  & echo #Another#STRING#

示例1:它工作并生成退出代码= 0。这很好。 注意“。”，直接在echo之后。

C:\Users\phife.狗\ gitrepos \ 1 # \ repo_abc \脚本 @echo。| set /p JUNK_VAR=这是一个像Linux echo一样显示的消息-n将显示它…&回显%ERRORLEVEL%

这是一个像Linux echo -n一样显示的消息…0

示例2:这可以工作，但产生退出代码= 1。这很糟糕。 请注意回声后面缺少“。”。这似乎就是不同之处。

C:\Users\phife.狗\ gitrepos \ 1 # \ repo_abc \脚本 @echo | set /p JUNK_VAR=这是一个像Linux echo -n会显示它的消息…&回显%ERRORLEVEL%

这是一个像Linux echo -n一样显示的消息…1

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
setlocal disableDelayedExpansion
call :writeInitialize

: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
::
if not defined %~1 exit /b
setlocal enableDelayedExpansion
if not defined $write.sub call :writeInitialize
set $write.special=1
if "!%~1:~0,1!" equ "^!" set "$write.special="
for /f delims^=^ eol^= %%A in ("!%~1:~0,1!") do (
  if "%%A" neq "=" if "!$write.problemChars:%%A=!" equ "!$write.problemChars!" set "$write.special="
)
if not defined $write.special (
  <nul set /p "=!%~1!"
  exit /b
)
>"%$write.temp%_1.txt" (echo !str!!$write.sub!)
copy "%$write.temp%_1.txt" /a "%$write.temp%_2.txt" /b >nul
type "%$write.temp%_2.txt"
del "%$write.temp%_1.txt" "%$write.temp%_2.txt"
set "str2=!str:*%$write.sub%=%$write.sub%!"
if "!str2!" neq "!str!" <nul set /p "=!str2!"
exit /b


:writeInitialize
::
:: Defines 3 variables needed by the :write and :writeVar routines
::
::   $write.temp - specifies a base path for temporary files
::
::   $write.sub  - contains the SUB character, also known as <CTRL-Z> or 0x1A
::
::   $write.problemChars - list of characters that cause problems for SET /P
::      <carriageReturn> <formFeed> <space> <tab> <0xFF> <equal> <quote>
::      Note that <lineFeed> and <equal> also causes problems, but are handled elsewhere
::
set "$write.temp=%temp%\writeTemp%random%"
copy nul "%$write.temp%.txt" /a >nul
for /f "usebackq" %%A in ("%$write.temp%.txt") do set "$write.sub=%%A"
del "%$write.temp%.txt"
for /f %%A in ('copy /z "%~f0" nul') do for /f %%B in ('cls') do (
  set "$write.problemChars=%%A%%B    ""
  REM the characters after %%B above should be <space> <tab> <0xFF>
)
exit /b

Late answer here, but for anyone who needs to write special characters to a single line who find dbenham's answer to be about 80 lines too long and whose scripts may break (perhaps due to user-input) under the limitations of simply using set /p, it's probably easiest to just to pair your .bat or .cmd with a compiled C++ or C-language executable and then just cout or printf the characters. This will also allow you to easily write multiple times to one line if you're showing a sort of progress bar or something using characters, as OP apparently was.

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。
