退出 Iterm 重開

$ git clone --depth=1 https://github.com/romkatv/powerlevel10k.git $ZSH_CUSTOM/themes/powerlevel10k

修改.zshrc中的 ZSH_THEME參數為 powerlevel10k/powerlevel10k

$ sed 's/powerlevel9k/powerlevel10k/g' -i ~/.zshrc$ exec zsh

重新啟動ZSH

$ p10k configure

zsh-autosuggestions

這是ZSH上的一個套件，在你Terminal輸入指令時會依照 history（以前輸入過的同樣指令）幫你自動完成。

It suggests commands as you type based on history and completions.

Requirements: Zsh v4.3.11 or later

下載autosuggestions到目錄底下的plugins位置

$ git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

$ vim ~/.zshrc

找到.zshrc檔案中 plugins參數這一行（如果沒有的話自己新增）

plugins=(zsh-autosuggestions)

如果有多個套件，則以空格隔開

plugins=(git zsh-autosuggestions)

之後重新載入

$ source ~/.zshrc

便有自動完成提示的功能，當灰字出現時直接 按 →（方向鍵右）就能自動完成。
