## Zsh 介绍 ##

*  Zsh 兼容 Bash，据传说 99% 的 Bash 操作 和 Zsh 是相同的
 *  Zsh 官网：[http://www.zsh.org/][http_www.zsh.org]
 *  先看下你的 Linux支持哪些 shell：`cat /etc/shells`，正常结果应该是这样的：

/bin/sh
    /bin/bash
    /sbin/nologin
    /bin/dash
    /bin/tcsh
    /bin/csh

*  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 ##
    
     *  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][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（这个过程可能会有点慢，或者需要重试几次）：`wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O - | sh`
     *  整个过程效果如下图：

*  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`
 *  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：

现在zsh和oh-my-zsh都安装好了，现在重点讲下zsh的配置!

创建~/.zshrc配置文件，先给看下我的配置，可以凭自己喜好更改：

# 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=/home/amoscykl/.oh-my-zsh
    
    # Set name of the theme to load. Optionally, if you set this to "random"
    # it'll load a random theme each time that oh-my-zsh is loaded.
    # See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
    # zhs的主题
    ZSH_THEME="ys"		
    # Set list of themes to load
    # Setting this variable when ZSH_THEME=random
    # cause zsh load theme from this variable instead of
    # looking in ~/.oh-my-zsh/themes/
    # An empty array have no effect
    # ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )
    
    # Uncomment the following line to use case-sensitive completion.
    # CASE_SENSITIVE="true"
    
    # Uncomment the following line to use hyphen-insensitive completion. Case
    # sensitive completion must be off. _ and - will be interchangeable.
    # HYPHEN_INSENSITIVE="true"
    
    # Uncomment the following line to disable bi-weekly auto-update checks.
    # DISABLE_AUTO_UPDATE="true"
    
    # Uncomment the following line to change how often to auto-update (in days).
    # export UPDATE_ZSH_DAYS=13
    
    # Uncomment the following line to disable colors in ls.
    # DISABLE_LS_COLORS="true"
    
    # Uncomment the following line to disable auto-setting terminal title.
    # DISABLE_AUTO_TITLE="true"
    
    # Uncomment the following line to enable command auto-correction.
    # ENABLE_CORRECTION="true"
    
    # Uncomment the following line to display red dots whilst waiting for completion.
    # COMPLETION_WAITING_DOTS="true"
    
    # Uncomment the following line if you want to disable marking untracked files
    # under VCS as dirty. This makes repository status check for large repositories
    # much, much faster.
    # DISABLE_UNTRACKED_FILES_DIRTY="true"
    
    # Uncomment the following line if you want to change the command execution time
    # stamp shown in the history command output.
    # The optional three formats: "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"
    # HIST_STAMPS="mm/dd/yyyy"
    
    # 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? (plugins can be found in ~/.oh-my-zsh/plugins/*)
    # Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
    # Example format: plugins=(rails git textmate ruby lighthouse)
    # Add wisely, as too many plugins slow down shell startup.
    
    # z命令快速跳转目录     x命令解压一切文件         命令行可以直接google  
    plugins=(
      git z zsh-autosuggestions extract web-search zsh-syntax-highlighting 
    )
    
    source $ZSH/oh-my-zsh.sh
    
    # User configuration
    
    # export MANPATH="/usr/local/man:$MANPATH"
    
    # You may need to manually set your language environment
    # export LANG=en_US.UTF-8
    
    # Preferred editor for local and remote sessions
    # if [[ -n $SSH_CONNECTION ]]; then
    #   export EDITOR='vim'
    # else
    #   export EDITOR='mvim'
    # fi
    
    # Compilation flags
    # export ARCHFLAGS="-arch x86_64"
    
    # ssh
    # export SSH_KEY_PATH="~/.ssh/rsa_id"
    
    # 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"
    #
    #自动补全插件
    source ~/.oh-my-zsh/plugins/incr/incr.zsh
    
    # 自动更新的时间间隔，单位是天，这里设置 30 天更新一次
    export UPDATE_ZSH_DAYS=1

最终效果：

主题：

![70][]

自动补全：

![70 1][]

一键google：

![70 2][]

![70 3][]

z命令快速跳转目录(根据记录):

![70 4][]

x命令自动解压各种压缩文件，不用再牢记繁杂的解压命令！

![70 5][]

我常用的配置基本就这些，还可以添加更多的插件来武装你的shell！
