今天登錄linux測試機，想要創建目錄，ls的時候，找不到之前的的目錄，才發現是目錄不對的問題。
首先，先要弄清楚 [root@330c353813ea ~] 和 [root@330c353813ea /] 區別
[root@330c353813ea ~] 是linux主目錄,相當於/root
[root@330c353813ea /] 是根分區,相當於根目錄
➜ ~ ssh root@xxx //登錄linux
root@xxx's password: //輸入密碼

[root@330c353813ea ~]# pwd //查看目前所在的工作目錄的絕對路徑
/root
[root@330c353813ea ~]# ls //顯示當前目錄下的內容
