| # 在 remote 執行指令
run()
# 在 remote 執行需要 sudo 的指令
sudo()
# 在 localhost 執行指令
local()
# 在 remote 執行 change directory&＃xff0c;通常會搭配 with 使用
cd()
# 在 localhost 執行 change directory
lcd()

cd()、run()、sudo() 只能用在 remote SSH 登入&＃xff0c;本機的話要用 lcd()、local()、local(&＃39;sudo some_command&＃39;)。
run() 默認的工作目錄就是 SSH 登入進去的家目錄&＃xff0c;local(), 則是 fabfile.py 所在的目錄。

Example
我把 deploy 環境分成三種&＃xff0c;production、staging、development&＃xff0c;分別對應到一個 fabfile。fabfile 實際上就是一個 .py 檔案&＃xff0c;因為 Fabric 說穿了就是用 Python 來寫一串 bash 指令。
目錄結構如下&＃xff1a;
