转义以正斜杠和问号开头的批处理文件回显
有点棘手。如何在批处理文件中正确转义以下内容？
echo /? display this help text
这种特殊的字符组合被视为“ECHO /？”命令：
C:\Batch>ECHO /? display this help text
Displays messages, or turns command-echoing on or off.
ECHO [ON | OFF]
ECHO [message]
Type ECHO without parameters to display the current echo setting.
它不响应插入符 (^) 转义，即。我试过了^/? /^?和 ^/^?。
注意：作为一种解决方法，我发现在中间插入其他字符足以绕过 ECHO 命令行处理器，例如：
echo ... /? display this help text
尽管如此，这并不理想，我想知道是否有一种方法可以实现所需的输出，即使用 /？在回显消息的开头。
Bit of a tricky one. How can I correctly escape the following in a batch file?
echo /? display this help text
This particular combination of characters is treated as an "ECHO /?" command:
C:\Batch>ECHO /? display this help text
Displays messages, or turns command-echoing on or off.
ECHO [ON | OFF]
ECHO [message]
Type ECHO without parameters to display the current echo setting.
It does not respond to caret (^) escaping, ie. I've tried ^/? /^? and ^/^?.
NB: As a workaround, I found that inserting other characters in between is enough to bypass the ECHO command line processor, eg:
echo ... /? display this help text
Still, this is not ideal and I wondered if there was a way to acheive the desired output, namely with /? at the start of the echoed message.
