程序员对Mac OS 初次使用的体验

作为一名屌丝，对Mac OS这样一款传说中的操作系统一直是只能远观。近日在姻缘巧合之下，有幸在公司得到一台Mac台式机，借此机会感受下与常用的Windows7以及CentOS\Ubuntu\Fedora等Linux1系列操作系统的感知差异。

联网（Mac OS 如何联有线网络）

这时我发现Mac的配置与Linux极其相似。（我的工作环境需要设置固定IP才可惜联网）

->左上角苹果图标->系统偏好设置->网络->以太网->设置IP

五笔输入法（Mac OS 如何使用五笔输入法）

->右上角输入法图标->输入偏好设置->“+”号增加输入法（“-”号是删除）->选择五笔（或拼音）

作为一名五笔玩家，刚开始发现Mac自带的五笔实在是不好用，很多时候只能的单字，许多的常用词组都不能识别，而且还不支持混输（这里指输入不流畅）。
不过，使用了一会之后，发现使用习惯的原因占很大的比重，所以耐心等自己慢慢习惯喽。

常用切换输入法的方式：

切换中英文方式：
1. Ctrl + Space（空格）
2. Caps Lock（大小写锁定）

打开终端（Mac OS 如何使用Terminal终端）

左下角Finder->应用程序->实用工具->终端

由于终端Terminal才是程序员最需要且最有用的应用，所以先将其放入下方的快捷方式。

到这里，发现 ls、cd、pwd等命令都是可以正常使用的，看来，传说Mac源于Unix的传言果然不虚。

增加root用户（Mac OS如何增加root用户）

macdeiMac:Applications xiaoqw$ su rootPassword:su: Sorry #这里还不能切换为root用户macdeiMac:Applications xiaoqw$ sudo sush-3.2# passwd rootChanging password for root.New password:Retype new password:sh-3.2# sh-3.2# sh-3.2# exitexitmacdeiMac:Applications xiaoqw$ su #这里已经可以了Password:sh-3.2# sh-3.2# sh-3.2# ls

如何安装brew（Mac OS 如何用命令行的方式安装软件）

sh-3.2# curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1

安装后使用brew安装软件时出现几个ERROR：

Error: Unknown command: install
Error: Unknown command: uninstall

解决方法：

执行brew发现问题的原因是brew的版本需要更新，执行brew update，按照提示信息操作，最后解决问题。

主要命令：

macdeiMac:/ xiaoqw$ sudo chown -R $(whoami) /usr/localmacdeiMac:/ xiaoqw$ sudo chown root:wheel /usr/localmacdeiMac:/ xiaoqw$ brew update

具体过程记录如下：
