Bit。 我怎么能够正确地在批量档案中逃脱以下内容?
echo /? display this help text
这种特殊特性组合被视为“ECHO /?”指挥:
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.

echo ... /? display this help text
然而,这并不理想,我想知道,在发出呼应信息时,是否有办法调和预期产出。

echo...my.bat这些人没有独立档案
echo/?
echo,/?
echo;/?只有<代码>echo()似乎总是可以安全地反对任何内容。
