所以代码这么修改也行：

@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 # Additionally, comments (such as these^) may be inserted on individual

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 ) >11.txt
pause >nul
