[文本处理] [已解决]批处理里面括号也需要转义吗？

在这段代码里，括号不转义的话，就会一闪而过

@echo off
(echo # This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
echo #
echo # This file contains the mappings of IP addresses to host names. Each   
echo # entry should be kept on an individual line. The IP address should
echo # be placed in the first column followed by the corresponding host name.  
echo # The IP address and the host name should be separated by at least one
echo # space.
echo #
echo # Additionally, comments ^(such as these^) may be inserted on individual
echo # lines or following the machine name denoted by a '#' symbol. 
echo # For example:
echo # 
echo #      102.54.94.97     rhino.acme.com          # source server 
echo #       38.25.63.10     x.acme.com              # x client host
echo 127.0.0.1 localhost ) >E:\1.txt
pause >nul
复制代码

以下代码中括号又不用转义

echo (dsfdf(sdfsdf)) >>e:\1.txt
复制代码

为什么会这样呢？

回复 2# CrLf


    谢谢了。
针对我碰到的这个情况，应该是这样的：如下代码
(echo # Additionally, comments (such as these) may be inserted on individual)>>e:\1.txt
批处理应该是把(echo # Additionally, comments (such as these)看成是一个完整的括号，然后就出错退出了。所以需要转义。
