配置ohmysh

1. 下載zsh

git clone https://github.com/ohmyzsh/ohmyzsh.git ~/.oh-my-zsh

2. [optional] 備份~/.zshrc

cp ~/.zshrc ~/.zshrc.orig

3. 復制模板中的zsh

cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

4. 可選的插件
   建議安裝，大大提升使用體驗，代碼自動補全和命令行高亮

git clone https://github.com/zsh-users/zsh-autosuggestions.git ~/.oh-my-zsh/plugins/zsh-autosuggestionsgit clone https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/plugins/zsh-syntax-highlighting
vim ~/.zshrc

把插件名稱加入其中

plugins=(gitzsh-autosuggestionszsh-syntax-highlighting)

保存退出

source ~/.zshrc
