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...

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

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。

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

您可以使用::或rem进行注释。

注释时，使用::，因为它快3倍。这里显示了一个示例

只有当注释在if中时，才使用rem，因为冒号可能会出错，因为它们是一个标签。
