Linux终极shell-zsh的完美配置方案！——oh-my-zsh

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/
• 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
  • 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：

自动补全：

一键google：

z命令快速跳转目录(根据记录):

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！

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！
