参考:https://github.com/robbyrussell/oh-my-zsh/

          https://github.com/robbyrussell/oh-my-zsh/wiki/Themes#agnoster

          http://logicmd.net/2012/11/installing-zsh-on-ubunt/

 

移除之前可能的oh-my-zsh的安装。

sudo apt-get install zsh git

if [ -d ~/.oh-my-zsh ]; then

    rm -r ~/.oh-my-zsh

fi

 

安装完成后设置当前用户使用 zsh:

chsh -s /bin/zsh

 

安装 git。

sudo apt-get install git

 

然后把shell切换成zsh,并重启计算机。

chsh -s `which zsh`

sudo shutdown -r 0

 

配置主要集中在用户当前目录的.zshrc里,用 vim 或你喜欢的其他编辑器打开.zshrc,在最下面会发现这么一行字:

 

# Customize to your needs…

 

 

接下来进行别名的设置,我自己的部分配置如下: 

alias ll='ls -l'

alias la='ls -a'

alias vi='vim'

alias javac="javac -J-Dfile.encoding=utf8"

alias grep="grep --color=auto"

alias -s html=mate   # 在命令行直接输入后缀为 html 的文件名,会在 TextMate 中打开

alias -s rb=mate     # 在命令行直接输入 ruby 文件,会在 TextMate 中打开

alias -s bz2='tar -xjvf'

zsh 的牛粪之处在于不仅可以设置通用别名,还能针对文件类型设置对应的打开程序,比如:

alias -s html=mate,意思就是你在命令行输入 hello.html,zsh会为你自动打开 TextMat 并读取 hello.html; alias -s gz='tar -xzvf',表示自动解压后缀为 gz 的压缩包。

 

 

默认主题是:

ZSH_THEME="robbyrussell"

 

设置默认的user

DEFAULT_USER=‘’

 

可以自己命名,例如:lzyfn.zsh-theme ,内容为下面的,需要添加字体:

cd~/.fonts/ && git clone https://github.com/scotu/ubuntu-mono-powerline.git 

 

    主题 lzyfn.zsh-theme

### Segment drawing

CURRENT_BG='NONE'

  local LC_ALL="" LC_CTYPE="en_US.UTF-8"
  # NOTE: This segment separator character is correct.  In 2012, Powerline changed
  # the code points they use for their special characters. This is the new code point.
  # If this is not working for you, you probably have an old version of the
  # Powerline-patched fonts installed. Download and install the new version.
  # Do not submit PRs to change this unless you have reviewed the Powerline code point
  # history and have new information.
  # This is defined using a Unicode escape sequence so it is unambiguously readable, regardless of
  # what font the user is viewing this source code in. Do not replace the
  # escape sequence with a single literal character.
  # Do not change this! Do not make it '\u2b80'; that is the old, wrong code point.

oh my zsh 项目提供了完善的插件体系,相关的文件在~/.oh-my-zsh/plugins目录下,默认提供了100多种,大家可以根据自己的实际学习和工作环境采用,想了解每个插件的功能,只要打开相关目录下的 zsh 文件看一下就知道了。插件也是在 ~.zshrc 配置文件里,找到plugins关键字,你就可以加载自己的插件了,系统默认加载 git ,你可以在后面追加内容,如下:

 

plugins=(rails3 rails git textmate ruby rvm gem git github brew bundler textmate pow)

下面简单介绍几个:

 

1、git:当你处于一个 git 受控的目录下时,Shell 会明确显示 「git」和 branch,如上图所示,另外对 git 很多命令进行了简化,例如 gco=’git checkout’、gd=’git diff’、gst=’git status’、g=’git’等等,熟练使用可以大大减少 git 的命令长度,命令内容可以参考~/.oh-my-zsh/plugins/git/git.plugin.zsh

 

2、textmate:mr可以创建 ruby 的框架项目,tm finename 可以用 textmate 打开指定文件。

 

3、osx:tab 增强,quick-look filename 可以直接预览文件,man-preview grep 可以生成 grep手册 的pdf 版本等。

 

4、autojump:zsh 和 autojump 的组合形成了 zsh 下最强悍的插件,今天我们主要说说这货。

 

首先安装autojump,如果你用 Mac,可以使用 brew 安装:

 

brew install autojump

如果是 Linux,去下载 autojump 的最新版本,比如:

 

wget https://github.com/downloads/joelthelion/autojump/autojump_v21.1.2.tar.gz

解压缩后进入目录,执行

 

./install.sh

最后把以下代码加入.zshrc:

 

[[ -s ~/.autojump/etc/profile.d/autojump.sh ]] && . ~/.autojump/etc/profile.d/autojump.sh

至此,安装、配置、插件三位一体,终极 Shell 全面登场。退出终端会话重新登录,开始感受 zsh 的训疾如风!
