本文以Ubuntu 12.04 LTS为例，安装目前比较流行的zsh的配置oh-my-zsh。 oh-my-zsh最初是在OS X上供人使用，使用方法见此处。在Ubuntu上安装oh-my-zsh稍有不同。

安装

先安装zsh和git，同时移除之前可能的oh-my-zsh的安装。

4
sudo apt-get install zsh git
if [ -d ~/.oh-my-zsh ]; then
     rm -r ~/.oh-my-zsh
fi

手动安装zsh是用于Ubuntu的 sh 比较诡异，不识别 source 这个指令。装好zsh后仿OS X

?
1
wget https: //github .com /robbyrussell/oh-my-zsh/raw/master/tools/install .sh -O - | zsh

然后把shell切换成zsh，并重启计算机。

?

2
chsh -s ` which zsh`
sudo shutdown -r 0

关于这个诡异问题的详细讨论见github上此issue

配置

oh-my-zsh有大量精美主题托管在项目中，可以在此预览 https://github.com/robbyrussell/oh-my-zsh/wiki/themes，我看中了其中最拉风的一款agnoster。把配置过程记录如下。

  • 为了能够显示诸如分支（branch）、闪电（这个符号应该指拿到root权限）、错误(红色叉叉)、后台（一个齿轮）的各种符号，必须使用一个patch过的字体，在ubuntu下默认是Ubuntu Mono，OS X下坐着配的是Menlo，很多常见的等宽字体都打好了patch，当然也可以自己手动打patch。

    cd ~/.fonts/ && git clone https: //github .com /scotu/ubuntu-mono-powerline .git && cd ~
  • 在 ~/.zshrc 把主题设置为 agnoster
  • 在 ~/.zshrc 设定 DEFAULT_USER 变量可以使得即使登陆在本机（即非SSH到远程）时也能显示“user@hostname”

这是我做的效果，Solarized Dark colorscheme这个配色没有适用于Ubuntu Terminal的。

以下是我的 .zshrc ，只开了git一个plugin，还有很多plugin在 ~/.oh-my-zsh/plugin/ 目录下，原来的sublime的plugin有点bug，我就放在我的.zshrc的配置文件里面了。
