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。

在电脑速度不是很快的年代，::代替快速眼动是最好的选择。 REM'ed行被读取，然后忽略。:“埃德一行都被忽略了。”这可以在“过去”加速你的代码。而且在快速眼动之后你需要一个空间，在::之后你不需要。

正如第一条评论所说:你可以在任何你觉得需要的行中添加信息

SET DATETIME=%DTS:~0,8%-%DTS:~8,6% ::Makes YYYYMMDD-HHMMSS

至于跳过的部分。 把REM放在每一行的前面是相当耗时的。 如前所述，使用GOTO跳过部分是跳过大块代码的一种简单方法。确保在希望代码继续的位置设置:LABEL。

SOME CODE

GOTO LABEL  ::REM OUT THIS LINE TO EXECUTE THE CODE BETWEEN THIS GOTO AND :LABEL

SOME CODE TO SKIP
.
LAST LINE OF CODE TO SKIP

:LABEL
CODE TO EXECUTE

The rem command is indeed for comments. It doesn't inherently update anyone after running the script. Some script authors might use it that way instead of echo, though, because by default the batch interpreter will print out each command before it's processed. Since rem commands don't do anything, it's safe to print them without side effects. To avoid printing a command, prefix it with @, or, to apply that setting throughout the program, run @echo off. (It's echo off to avoid printing further commands; the @ is to avoid printing that command prior to the echo setting taking effect.)

所以，在你的批处理文件中，你可以使用这个:

@echo off
REM To skip the following Python commands, put "REM" before them:
python foo.py
python bar.py

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

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...
