在制作airflow docker镜像时，需要修改airflow源码，使其显示时间为本地时间，通过 sed命令可实现对镜像中文件的修改。

通过指定行号修改：

    在指定行号后增加内容：sed -i -e ‘行号a内容’ 文件路径

    替换指定行号的内容：sed -i -e ‘行号c内容’ 文件路径

    在指定行号前增加内容：sed -i -e ‘行号i内容’ 文件路径

也可以通过匹配内容进行修改：

    匹配行前修改：sed -i '/要匹配的内容/a修改后的内容' 文件路径

    匹配行后修改：sed -i '/要匹配的内容/i修改后的内容' 文件路径

    替换匹配行：sed -i '/要匹配的内容/c替换后的内容' 文件路径
