Linux-nano编辑器.doc

Linux nano文本编辑器被nano编辑器折腾了半天，收藏一下吧。省得以后到处找我们以后基本都需要编辑文件来实现不同的设置，那么我们用什么来设置配置文件呢，用编辑器，就好比windows下的记事本和写字板，我们今天就来讲一下debian的默认编辑器-nano首先我们在网络上看看有没nano的资料网络上很少有nano的资料，那么我就来 给大家讲解一下nano的使用吧就以编辑网络配置文件为例子吧GNU nano 1.2.4，nano的版本 File: /etc/network/interfaces打开的文件的绝对地址下面就是打开的文件的内容# This file describes the network interfaces available on your system# and how to activate them.
