iTerm2 介绍
iTerm2 是一款功能强大的终端工具，也可以说是 Terminal 的替代品，也可以说是 iTerm 的后继产品。它适用于 macOS 10.12 或更高版本的 macOS。
它支持分窗口操作、自动补齐、粘贴历史、回放功能、全屏等功能，是一款非常强大、非常值得推荐的终端工具。
安装 iTerm2
官网下载包安装：http://iterm2.com/
使用Homwbrew安装：
brew install iterm2iTerm2配置主题
iTerm2 最常用的主题是 Solarized Dark theme，下载地址：https://ethanschoonover.com/solarized
下载的是压缩文件，你先解压一下，然后打开 iTerm2，按 【Command + , 】键，打开 Preferences 配置界面，然后 Profiles -> Colors -> Color Presets -> Import，选择刚才解压的 solarized -> iterm2-colors-solarized -> Solarized Dark.itermcolors 文件，导入成功，最后选择 Solarized Dark 主题，就可以了，如下所示：
该工具主题有很多，可以根据自己的爱好进行选择。
配置 oh-my-zsh
oh-my-zsh 是对主题的进一步扩展，Github 地址：https://github.com/ohmyzsh/ohmyzsh
你可以通过 curl 或 wget 命令进行安装：
curl 安装
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"wget 安装
sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"例如，我这里通过 curl 命令进行安装：
$ sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
Cloning Oh My Zsh...
xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.

$ chsh -s /bin/zsh然后，我们用 vim 命令编辑 ~/.zshrc 文件，将主题配置修改为 ZSH_THEME=”agnoster”。
$ vim ~/.zshrc
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
# Path to your oh-my-zsh installation.
export ZSH="/Users/linan/.oh-my-zsh"
# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
ZSH_THEME="agnoster" // 修改主题agnoster 是比较常用的 zsh 主题之一，你可以挑选你喜欢的主题，zsh 主题列表：https://github.com/ohmyzsh/ohmyzsh/wiki/themes
配置 Meslo 字体
使用上面的主题，需要 Meslo 字体支持，要不然会出现乱码的情况，字体下载地址：Meslo LG M Regular for Powerline.ttf
下载好之后，直接在 macOS 中双击安装即可。
然后打开 iTerm2，按【Command + , 】键，打开 Preferences 配置界面，然后 Profiles -> Text -> Font -> Chanage Font，选择 Meslo LG M Regular for Powerline 字体。 
当然，如果你觉得默认的12px字体大小不合适，可以自己进行修改。
另外，VS Code 的终端字体，也需要进行配置，打开 VS Code，按 Command + ,键，打开用户配置，搜索 fontFamily，然后将右边的配置增加”terminal.integrated.fontFamily”: “Meslo LG M for Powerline”，示例：
声明高亮
效果就是上面截图的那样，特殊命令和错误命令，会有高亮显示。
使用 Homebrew 安装：
$ brew install zsh-syntax-highlighting安装成功之后，用 vim 命令编辑 ~/.zshrc 文件，在最后一行增加下面配置：
...................
# Compilation flags
# export ARCHFLAGS="-arch x86_64"
# Set personal aliases, overriding those provided by oh-my-zsh libs,
# plugins, and themes. Aliases can be placed here, though oh-my-zsh
# users are encouraged to define aliases within the ZSH_CUSTOM folder.
# For a full list of active aliases, run `alias`.
#
# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"
source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh保存后，执行变量生效命令：
source /etc/profile自动补齐
这个功能是非常实用的，可以方便我们快速的敲命令。
配置步骤，先克隆 zsh-autosuggestions 项目，到指定目录：
$ git clone https://github.com/zsh-users/zsh-autosuggestions ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions然后，用 vim 命令编辑 ~/.zshrc 文件，找到 plugins 配置，增加 zsh-autosuggestions 插件：
# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder
# Which plugins would you like to load?
# Standard plugins can be found in $ZSH/plugins/
# Custom plugins may be added to $ZSH_CUSTOM/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git zsh-autosuggestions)iTerm2 常用命令快捷键
