command patterns and practices

查找文件格式：/需要查找的内容如：/dnsmasq 直接回车就可以高亮显示出匹配查找的内容，按n 是查找下一个按N 是往上查找也可以用？查找需要的内容，n和N的用法和/相反命令行模式下的替换1,100s/new/old/g1,100是需要替换的范围，表示1到100行进行替换，s表示行g 是全局替换，即替换匹配到的所有内容1$s/new/old/g  是替换文件内所有的匹配字段如果文件中需要替换一个路径或者有特殊字符的需要脱意字符\或者换一个分割符把脱意字符换成#号代替脱意1,100s#/root#/ROOT#g passwd   将1到最后一行中的/root替换成/ROOT，g立即替换所有的不进行确认wq!   保存退出q!    不保存退出x    退出不跟新mtime时间

Then press ' I ' to enter edit mode, and then paste the copied code content so that it does not automatically indent.
In some cases the set Noai Nosi command does not work, and you can try to use set paste to manipulate
