巧用vim sed整理shell脚本文件-凯发app官方网站

在工作中遇到的问题，此nginx配置脚本我在googel下载下来的，实际复制贴貼到服务器中运行时发现前面都有 001-100的行标识符，外带空格，影响运行和美观啊；本来想一行行删除，后来不禁自己也鄙视自己：这也太没技术含量了吧?具体解决方法如下:①首先在 vim里删除所有行首数字，:%s/^[0-9][0-9]* // ；②然后再删除所有行首空字符，sed -i 's/^[[:space:]]*//' nginxd.sh 解决问题，整个nginxd.sh脚本如下，有兴趣的朋友也拿着练下手。

另注：这个文件我找得比较简单，后来我发现用sed -i 's/[0-9]* //g' nginxd.sh就满足我的需求了，希望大家找下比较难的脚本测试～
