不，普通的批处理文件使用REM作为注释。ECHO是在屏幕上打印内容的命令。

要“注释掉”文件的部分，您可以使用GOTO。所有这些命令/技术的示例:

REM it starts here the section below can be safely erased once the file is customised
ECHO Hey you need to edit this file before running it!  Check the instructions inside
ECHO Now press ctrl-c to interrupt execution or enter to continue
PAUSE
REM erase the section above once you have customised the file
python executed1.py
ECHO Skipping some stuff now
GOTO End
python skipped1.py
python skipped2.py
:END
python executed2.py

我能说什么呢?批处理文件是时代的遗迹，它们笨重而丑陋。

编辑:修改了示例，使其包含你显然正在寻找的元素。

我更喜欢用:

REM评论 &REM内联注释

例子:

@echo off
set parameter1=%1%
REM test if the parameter 1 was received
if defined parameter1 echo The parameter 1 is %parameter1% &REM Display the parameter

多行注释

如果有大量的行你想注释掉，那么如果你能多行注释而不是每一行都注释掉会更好。

看看Rob van der Woude在评论区发布的这篇文章:

The batch language doesn't have comment blocks, though there are ways to accomplish the effect. GOTO EndComment1 This line is comment. And so is this line. And this one... :EndComment1 You can use GOTO Label and :Label for making block comments. Or, If the comment block appears at the end of the batch file, you can write EXIT at end of code and then any number of comments for your understanding. @ECHO OFF REM Do something • • REM End of code; use GOTO:EOF instead of EXIT for Windows NT and later EXIT Start of comment block at end of batch file This line is comment. And so is this line. And this one...

这是一个古老的话题，我想在这里补充我的理解，扩展这个有趣的话题的知识。

REM和::之间的关键区别是:

REM本身是一个命令，而::不是。

我们可以把::作为一个令牌，只要CMD解析器在一行中遇到第一个非空白空格，它就会跳过整行，读取下一行。这就是为什么REM后面至少应该有一个空格，以便能够作为该行的注释，而::后面不需要任何空格。

REM本身是一个命令，从下面的FOR语法可以更好地理解

基本的FOR语法如下

FOR %v in (set) DO <Command> [command param] 

这里<命令>可以是任何有效的命令 因此，我们可以编写以下有效的命令行，因为rem是一个命令

FOR %i in (1,2,3) DO rem echo %i

然而，我们不能把下面的行写成::不是命令

FOR %i in (1,2,3) DO :: echo %i

注释一行

对于注释行，使用REM或::though::可能会在括号内失败

在以!<分隔符开头的延迟展开行中，>将被忽略，因此可以用于注释:

@echo off

setlocal enableDelayedExpansion

echo delayed expansion activated
!;delayed expansion commented line
echo end of the demonstration

在行末注释

对于行末的注释，您可以再次使用rem和::结合&:

echo --- &:: comment (should not be the last line in the script)
echo --- &rem comment

在文件末尾注释

因为exit命令后会被解析，你可以使用它在文件末尾添加注释:

@echo off

echo commands

exit /b 

-------------------
commnts at the end 
of the file
------------------

内联注释

不存在的变量的展开将被什么都不替换，并且设置一个变量=相当困难，你可以在内联注释中使用这个:

@echo off

echo long command %= this is a comment =% with an inline comment

多行注释

对于多行注释，可以使用GOTO(用于括号外)和REM带有条件执行(用于括号内)。详情如下:

@echo off

echo starting script

goto :end_comments
 comented line 
 one more commented line
:end_comments

echo continue with the script

(
    echo demonstration off
    rem/||(
      lines with
      comments
    )
    echo multiline comment inside
    echo brackets
)

同样的技术用宏来美化:

@echo off

::GOTO comment macro
set "[:=goto :]%%"
::brackets comment macros
set "[=rem/||(" & set "]=)"

::testing
echo not commented 1

%[:%
  multi 
  line
  comment outside of brackets
%:]%

echo not commented 2

%[:%
  second multi 
  line
  comment outside of brackets
%:]%

::GOTO macro cannot be used inside for
for %%a in (first second) do (
    echo first not commented line of the %%a execution
    %[%
        multi line
        comment
    %]%
    echo second not commented line of the %%a execution
)

你可以使用::或REM来注释一些东西:

your commands here
:: commenttttttttttt

or

your commands here
REM  commenttttttttttt

为了在同一行执行命令，你必须添加一个&号:

your commands here      & ::  commenttttttttttt

or

your commands here      & REM  commenttttttttttt

注意:

在嵌套逻辑(IF-ELSE, FOR循环等)中使用::将导致错误。在这种情况下，用REM代替。
