The command you're looking for is rem.
您正在寻找的命令是rem.
There is also a shorthand version ::, which sort of looks like #if you squint a bit and look at it sideways :-) I originally preferred the ::variant since I'm a bash-aholic and I'm still trying to forget the painful days of BASIC.
还有一个速记版本::，#如果你眯着眼睛看它的侧面看起来有点像:-) 我最初更喜欢这个::变体，因为我是一个bash-aholic 并且我仍然试图忘记 BASIC 的痛苦日子.
Unfortunately, there are situations where ::stuffs up the command line processor (such as within complex ifor forstatements) so I generally use remnowadays. In any case, it's a hack, suborning the label infrastructure to make it looklike a comment when it really isn't.
不幸的是，在某些情况下，::命令行处理器会被塞满（例如在复杂if或for语句中），所以我rem现在通常使用。在任何情况下，这是一种黑客行为，将标签基础设施转为使用，使其看起来像一条评论，但实际上并非如此。
You should also keep in mind that remisa command so you can't just bang it at the end of a line like the #in bash. It has to go where a command would go. For example, only the second of these two will echo the single word hello:
您还应该记住，这rem是一个命令，因此您不能像#in那样在行的末尾敲击它bash。它必须去到命令去的地方。例如，只有这两个中的第二个会回显单个单词hello：
echo hello rem a comment.
echo hello & rem a comment.

A comment is produced using the REM command which is short for "Remark".
使用 REM 命令生成注释，它是“Remark”的缩写。
REM Comment here...

Sometimes, it is convenient to add a comment to a command line. For that, you can use "&REM misc comment text" or, now that I know about it, "&:: misc comment text". For example:
有时，向命令行添加注释很方便。为此，您可以使用“&REM 杂项注释文本”，或者，现在我知道了，“&:: 杂项注释文本”。例如：
REM SET Token="4C6F72656D20697073756D20646F6C6F" &REM This token is for localhost
SET Token="722073697420616D65742C20636F6E73" &REM This token is for production
This makes it easy to keep track of multiple sets of values when doing exploration, tests of concept, etc. This approach works because '&' introduces a new command on the same line.
这使得在进行探索、概念测试等时很容易跟踪多组值。这种方法有效，因为“&”在同一行引入了一个新命令。

It's "REM".
是“REM”。
Example:
例子：
REM This is a comment
回答by PeterMmm
Lines starting with "rem" (from the word remarks) are comments:
以“rem”开头的行（来自单词注释）是注释：
rem comment here
echo "hello"
回答by Zimba
: this is one way to comment
As a result:
其结果：
:: this will also work
:; so will this
:! and this
Above styles work outsidecodeblocks, otherwise:
以上样式在代码块之外工作，否则：
REM is another way to comment.
