# DocumentRoot /var/www
DocumentRoot /home/cxl/web
<Directory />

# <Directory /var/www/>
<Directory /home/cxl/web/>
Options Indexes FollowSymLinks MultiViews

<Directory "/usr/lib/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
以上一段代码，想将“<Directory /var/www/>”后面内容的“AllowOverride None”替换为“AllowOverride All”，仅替换这一个，别的不变
用shell脚本怎么写？

sed '/<Directory \/var\/www\/>/,/AllowOverride None/s/AllowOverride None/AllowOverride All/' text
