使用 `^` 转义 Windows 批处理文件中的行尾字符在某些行上不起作用？
Using `^` to escape end-of-line character in a Windows Batch file doesn't work on certain lines?
我有一个批处理文件，我将它们放在一起以便通过单击自动启动一个程序和多个相关程序。问题相关部分：
echo Starting FireFox with Elite Tabset...
cd "C:\Program Files\Mozilla Firefox\"
start firefox.exe ^

echo Starting EDDiscovery...
如您所见，为了便于阅读，我使用 ^ 字符将 start firefox 命令分成多行。如图所示，该文件有效。但是，请注意倒数第二行，它以“file:///”开头。该行有多个参数。我试图做的是：

echo Starting EDDiscovery...
当我这样做时，我得到以下输出：

The filename, directory name, or volume label syntax is incorrect.

我不明白为什么我能够将前 4 个参数分开，但不能将以 "file:// 开头的参数分开。 ^ 是否有我遗漏或误用的一些微妙方面？这种清理有不同的技术吗？我承认这纯粹是一个可读性问题，但无法解释这种行为令人烦恼。
问题在于以双引号开头的行，因为行尾的插入符会转义行尾和下一行的第一个字符。
这导致转义第一个引号，而行尾的“结束”引号被解释为“开始”引号。
这可以通过简单地在每行前面加上 space.
来解决
start firefox.exe ^

https://www.edtutorials.com/ ^
"file:///C:/Program Files/guide.pdf" ^
"file:///C:/Program Files/blapdf" ^
...
对于这个问题，存在第二种更晦涩的解决方案，即在插入符号前添加重定向。
使用这种方法，下一行的第一个字符按预期工作（不会被转义）
