什么是HomeBrew
使用Homebrew安装 Apple（或您的 Linux 系统）没有预装但 你需要的东西。
安装HomeBrew
1.1将brew的install文件下载本地
cd ~ && curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_install
1.2修改install文件的镜像源
# BREW_REPO = "https://github.com/Homebrew/brew".freeze
BREW_REPO = "git://mirrors.ustc.edu.cn/brew.git".freeze
1.3安装brew
/usr/bin/ruby ~/brew_install
1.4验证是否安装成功
$ brew doctor
如果没成功先卸载brew一下，再试
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
如何使用 HomeBrew 安装软件
安装完 HomeBrew 后可使用以下命令进行软件包安装：
brew install 软件名称HomeBrew 常用命令
$ brew --help # 查看简洁帮助
$ man brew # 完整命令帮助
$ brew install [name] # 安装软件包
$ brew uninstall [name] # 卸载软件包
$ brew search [name] # 搜索软件包
$ brew list # 显示已经安装的所有软件包
$ brew update # 同步远程最新更新情况，对本机已经安装并有更新的软件用*标明
$ brew outdated # 查看已安装的哪些软件包需要更新
$ brew upgrade [name] # 更新单个软件包
$ brew info [name] # 查看软件包信息
$ brew home [name] # 访问软件包官方站
$ brew cleanup # 清理所有已安装软件包的历史老版本
$ brew cleanup [name] # 清理单个已安装软件包的历史版本
HomeBrew中安装的好用的三方软件
wget
1、安装wget
安装命令：brew install wget
检验是否安装成功：
安装成功后结果如下：
MacBook-Pro:~ home$ wget http://www.arefly.com/

Zsh 入门(安装及使用)
先看下你的 CentOS 支持哪些 shell：cat /etc/shells，正常结果应该是这样的：
MacBook-Pro:~ dunk$ cat /etc/shells
# List of acceptable shells for chpass(1).
# Ftpd will not allow users to connect who are not using
# one of these shells.
/bin/bash
/bin/csh
/bin/dash
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh
默认 CentOS / Ubuntu / Mac 系统用的是 Bash，倒也不是说 Bash 不好，而是说我们有更好的选择。
Zsh 安装
- CentOS 安装：
sudo yum install -y zsh Ubuntu 安装：sudo apt-get install -y zsh在检查下系统的 shell：cat /etc/shells，你会发现多了一个：/bin/zsh
使用 Zsh 扩展集合：oh-my-zsh
什么是Oh My Zsh
Oh My Zsh是一款社区驱动的命令行工具，正如它的主页上说的，Oh My Zsh 是一种生活方式。它基于zsh命令行，提供了主题配置，插件机制，已经内置的便捷操作。给我们一种全新的方式使用命令行。
Oh My Zsh这个名字听起来就很有意思，它是基于zsh命令行的一个扩展工具集，提供了丰富的扩展功能。
Oh My Zsh只是一个对zsh命令行环境的配置包装框架，但它不提供命令行窗口，更不是一个独立的APP。
- oh-my-zsh 帮我们整理了一些常用的 Zsh 扩展功能和主题：https://github.com/robbyrussell/oh-my-zsh
- 我们无需自己去捣搞 Zsh，直接用 oh-my-zsh 就足够了，如果你想继续深造的话那再去弄。
- 先安装 git：
sudo yum install -y git - 安装 oh-my-zsh
-
Basic Installation Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either curl or wget. via curl sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" via wget
// 这里使用 wgetsh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
- 在以 root 用户为前提下，oh-my-zsh 的安装目录：/root/.oh-my-zsh
- 在以 root 用户为前提下，Zsh 的配置文件位置：/root/.zshrc
- 为 root 用户设置 zsh 为系统默认 shell：
chsh -s /bin/zsh root 注意：这里安装的时候会有Do you want to change your default shell to zsh? [Y/n] 的选择，写Y然后回车就可以
- 如果你要重新恢复到 bash：
chsh -s /bin/bash root - 现在你关掉终端或是重新连上 shell，现在开头是一个箭头了，如下图：
-
Oh My Zsh目录结构
进入~/.oh-my-zsh目录后，看看该目录的结构
lib 提供了核心功能的脚本库
tools 提供安装、升级等功能的快捷工具
plugins 自带插件的存在放位置
templates 自带模板的存在放位置
themes 自带主题文件的存在放位置
custom 个性化配置目录，自安装的插件和主题可放这里
Zsh 配置
插件
- 启用 oh-my-zsh 中自带的插件。
- oh-my-zsh 的插件列表介绍（太长了，用源码不精准地统计下有 149 个）：https://github.com/robbyrussell/oh-my-zsh/wiki/Plugins
- 编辑配置文件：
vim /root/.zshrc，找到下图的地方，怎么安装，原作者注释写得很清楚了，别装太多了，默认 git 是安装的。
git 自动显示当前分支名称和修改状态
git 快捷键
https://github.com/ohmyzsh/ohmyzsh/blob/master/plugins/git/git.plugin.zsh
zsh帮我们配置了一些git的常常用命令简写，我常用的是几个命令
gst 代表 git status
# 添加当前目录的所有文件到暂存区 alias ga . =\'git add .\'
# 提交暂存区到仓库区 alias gcmsg =\'git commit -m\'
# 提交工作区自上次commit之后的变化，直接到仓库区 gca 代表 git commit -v -a\'
# 提交 alias gp =\'git push\'
# 切换到指定分支，并更新工作区 gco 代表 git checkout
# 列出所有本地分支 alias gb =\'git branch\'
# 列出所有本地分支和远程分支 alias gba =\'git branch -a\'
进入 ~/.zshrc配置文件，先给看下我的配置，可以凭自己喜好更改：
vim ~/.zshrc

默认是只有git
plugins=(git)
新增插件举例
- 安装zsh-syntax-highlighting语法高亮插件
下载插件
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc
编辑激活 ~/.zshrc配置文件
plugins=(git zsh-syntax-highlighting )
保存后 source一下，让改变生效
source ~/.zshrc
发现再敲命令就有颜色了，比如命令有误的时候是红色，命令正确的时候是绿色。
软件安装位置：cd ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions
oh my zsh 手动更新，可以执行
upgrade_oh_my_zsh
卸载oh my zsh
直接在终端中，运行uninstall_oh_my_zsh既可以卸载。
备注：
插件可以装很多，但是装多了之后会在每次进入命令提示符的时候明显变慢。慎用。
