Zsh 介紹

• Zsh 相容 Bash，據傳說 99% 的 Bash 操作 和 Zsh 是相同的
• 先看下你的 Linux支援哪些 shell：cat /etc/shells，正常結果應該是這樣的：

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

• 預設 CentOS / Ubuntu / Mac 系統用的是 Bash，倒也不是說 Bash 不好，而是說我們有更好的選擇。

  Zsh 安裝

  • CentOS 安裝：sudo yum install -y zsh
  • Ubuntu 安裝：sudo apt-get install -y zsh
  • 在檢查下系統的 shell：cat /etc/shells
    ，你會發現多了一個：/bin/zsh

  使用 Zsh 擴充套件集合：oh-my-zsh

  • 我們無需自己去搗搞 Zsh，直接用 oh-my-zsh 就足夠了，如果你想繼續深造的話那再去弄。
  • 先安裝 git：sudo yum install -y git
  • 安裝 oh-my-zsh（這個過程可能會有點慢，或者需要重試幾次）：wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O - | sh
  • 整個過程效果如下圖：

• 在以 root 使用者為前提下，oh-my-zsh 的安裝目錄：/root/.oh-my-zsh
• 在以 root 使用者為前提下，Zsh 的配置檔案位置：/root/.zshrc
• 為 root 使用者設定 zsh 為系統預設 shell：chsh -s /bin/zsh root
• 如果你要重新恢復到 bash：chsh -s /bin/bash root
• 現在你關掉終端或是重新連上 shell，現在開頭是一個箭頭了，如下圖：

建立~/.zshrc配置檔案，先給看下我的配置，可以憑自己喜好更改：

# 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的主題
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命令快速跳轉目錄     x命令解壓一切檔案         命令列可以直接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"
#
#自動補全外掛
source ~/.oh-my-zsh/plugins/incr/incr.zsh

# 自動更新的時間間隔，單位是天，這裡設定 30 天更新一次
export UPDATE_ZSH_DAYS=1

z命令快速跳轉目錄(根據記錄):

x命令自動解壓各種壓縮檔案，不用再牢記繁雜的解壓命令！

我常用的配置基本就這些，還可以新增更多的外掛來武裝你的shell！
