本課思維導(dǎo)圖
- 下載安裝 xshell 7 和 xftp 免費版都超級順利，登錄也超級順利，沒有遇到任何問題（就讓人怪不放心的，總覺得該出現(xiàn)點什么 bug 才行）
- 登錄之后熟悉基本命令，操作如下：
/usr/bin/xauth: file /home/bio04/.Xauthority does not exist
bio04@VM-0-6-ubuntu:~$ pwd

bio04@VM-0-6-ubuntu:~$ mkdir qingnan

- 關(guān)于自動補全：輸入字符后，按Tab 鍵，如果只有一個命令匹配到，按一次 Tab 鍵就自動將這個命令補全。
如果輸入的字符匹配多個命令則會列出所有可用的命令。
