问题描述
这不是很奇怪吗? .bat rem命令是否具有某种转义代码?
Isn't this weird? Do .bat rem commands have some kind of escape code?
file.bat:
rem https://sourceforge.net/p/jedit/bugs/4084/?limit=25
运行它:
C:\Users\admin>file.bat
25 was unexpected at this time.
C:\Users\admin>https://sourceforge.net/p/jedit/bugs/4084/?limit=25
我没有看到任何错误级别.
I don't see any errorlevel.
推荐答案
rem命令支持一个参数，即/?，对此它很贪心.您的URL包含该字符串.
The rem command supports one argument, namely /?, and it is greedy for it. Your URL contains that string.
=是标准的令牌分隔符(就像，，,，;一样)，因此其余部分似乎可以解释作为另一个(无效)命令.
The = is a standard token separator (just like , , ,, ;), and so the remainder seems to be interpreted as another (invalid) command.
由于不再检测到/?，因此将注释文本放在引号之间很有帮助:
Putting the remark text in between quotation marks helps here since /? is no longer detected:
rem "https://sourceforge.net/p/jedit/bugs/4084/?limit=25"
当您写这篇文章时:
rem/ https://sourceforge.net/p/jedit/bugs/4084/?limit=25
/?部分也不再被检测到.但是，然后会识别特殊字符，例如&，<，>，|，(和).
the /? portion is no longer detected too. However, special characters like &, <, >, |, ( and ) are then recognised.
另一种替代方法是使用::样式的注释，该注释实际上是无效的标签(标签以:开头，请参见goto /?和call /?):
Another alternative is to use a ::-style comment, which is actually an invalid label (labels begin with a :, see goto /? and call /?):
:: https://sourceforge.net/p/jedit/bugs/4084/?limit=25
特殊字符在这里不是问题，但是一定不能在带括号的代码块中使用.
Special characters are not a problem here, but this must not be used within a parenthesised block of code.
