#增加额外需要加入gfwlist的域名

#开始处理 gfwlist_domain_filename 内容
#方法1
sed -i 's/\./\\\\./g; s/\(.*\)/add regexp="(\\\\.|^)\1\\$" type=FWD forward-to=$gfwdns/g' ${gfwlist_domain_filename}

#方法2
#1、文件中域名的"."替换成"\\."
#sed -i 's/\./\\\\./g' ${gfwlist_domain_filename}

#2、每行行首增加字符串"add regexp="(\\.|^)"
#sed -i 's/^/add regexp="(\\\\.|^)&/g' ${gfwlist_domain_filename}

#3、每行行尾增加字符串"\$" type=FWD forward-to=$gfwdns"
#sed -i 's/$/&\\$" type=FWD forward-to=$gfwdns/g' ${gfwlist_domain_filename}

#4、在文件第1行前插入新行":local gfwdns 10.10.0.1"
sed -i '1 i:local gfwdns 192.168.53.1' ${gfwlist_domain_filename}

#5、在文件第2行前插入新行"/ip dns static remove [/ip dns static find type=FWD]"
sed -i '2 i/ip dns static remove [/ip dns static find type=FWD]' ${gfwlist_domain_filename}

#6、在文件第3行前插入新行"/ip dns static"
sed -i '3 i/ip dns static' ${gfwlist_domain_filename}

#6、删除文件尾的换行（可选）
#tail -n 1 ${gfwlist_domain_filename} | tr -d '\n' >> gfwlist_lastline_tmp
#sed -i '$d' ${gfwlist_domain_filename}
#sed -i '$r gfwlist_lastline_tmp' ${gfwlist_domain_filename}
#rm -f gfwlist_lastline_tmp
