【环境配置】常用软件

0. 设置环境变量的几种方式及区别

单一用户：.bashrc: 为每一个运行bash shell的用户执行此文件.当bash shell被打开时,该文件被读取。
打开用户主目录下的.bashrc，在这个文件中加入
export PATH=”$PATH:export PATH="$PATH:/home/***/android-sdk-linux_86/platform-tools/"
重启或注销就好了。

全局设置：
/etc/profile 是所有用户的环境变量
在/etc/profile中增加
export PATH="$PATH:/home/***/android-sdk-linux_86/platform-tools/"

系统设置：
/etc/enviroment是系统的环境变量
export PATH="$PATH:/home/***/android-sdk-linux_86/platform-tools/"

所以，当配置一个路径到profile和enviroment中后，新开一个终端，是不能使用默认命令的。
比如在profile和enviroment中设置了export PATH=****/android-sdk-linux_86/platform-tools后，
新开的终端中如果不source一下，是依然不能使用adb命令的，但是如果在.bashrc中设置了的话，新开的终端是可以直接使用adb的。

如果同一个变量在用户环境(/etc/profile)和系统环境(/etc/environment)有不同的值那应该是以用户环境为准了。
