2. 插件

• 安装incr自动补全插件推荐

cd ~/.oh-my-zsh/plugins/
mkdir incr && cd incr
wget http://mimosa-pudica.net/src/incr-0.2.zsh
nano ~/.zshrc 

source ~/.oh-my-zsh/plugins/incr/incr*.zsh    (add in the ~/.zshrc)

 

source ~/.zshrc

• 直接使用的插件推荐

nano ~/.zshrc

plugins=(git extract z)      (add in the ~/.zshrc)

 

source ~/.zshrc

• git

默认开启的插件，提供了大量 git 的alias.

• extract

功能强大的解压插件，所有类型的文件解压一个命令x全搞定，再也不需要去记tar后面到底是哪几个参数了.

• z

强大的目录自动跳转命令，会记忆你曾经进入过的目录，用模糊匹配快速进入你想要的目录.

3. 主题

nano ~/.zshrc

eg: 

• ZSH_THEME="robbyrussell" default

• 如果ZSH_THEME=""则不启用任何主题.

• 如果ZSH_THEME="random",那么每次打开一个新的终端窗口时，电脑会随机选择一个主题使用，echo $RANDOM_THEME可输出当前主题名称.

source ~/.zshrc
