一、什么是sed
sed（Stream EDitor）流编辑器，是一个非交互式的文本编辑器，它可以对文本文件和标准输入进行编辑，标准输入可以来自键盘输入、文件重定向、字符串、变量等。sed从文本的一个文本行或者标准输入中读取数据，将其复制到缓冲区，然后读取命令行或脚本的第一个命令，对此要求的行号进行编辑，重复此过程，直到命令行或者脚本中的所有命令都执行完毕。sed适用于以下三种场景：编辑相对交互式文本编辑器而言太大的文件。编辑命令太傅在，在交互式文本编辑器中难以输入的情况对文件扫描一遍，但是需要执行多个编辑函数的情况
二、sed命令组成部分
命令格式：sed [OPTION]... 'script' [input-file] ...[OPTION]:sed 命令选项script：sed脚本，由“地指定界编与辑命令组成”（注意此处地址定界与编辑命令中间没有任何符号）三、sed命令常用选项及脚本详解
