cd -返回之前的目錄

cd !$ 把上個命令的參數作為這個命令的參數

閱讀目錄(Content)

1.命令格式：

cd [目錄名]

2.命令功能

切換當前目錄至 [目錄名]

3. 常用范例

1.進入系統根目錄

命令：

cd /

說明：進入系統根目錄,上面命令執行完后拿ls命令看一下，當前目錄已經到系統根目錄了

輸出：

hc@hc-virtual-machine:~$ pwd

/home/hc

hc@hc-virtual-machine:~$ cd /

hc@hc-virtual-machine:/$ ls

bin dev initrd.img lib64 mnt root snap sys var

boot etc initrd.img.old lost+found opt run srv tmp vmlinuz

cdrom home lib media proc sbin swapfile usr

pwd的作用是查詢當前所在目錄

2. 返回父級目錄

命令：

cd ..

輸出：

hc@hc-virtual-machine:~/PycharmProjects$ pwd

/home/hc/PycharmProjects

hc@hc-virtual-machine:~/PycharmProjects$ cd ..

hc@hc-virtual-machine:~$ pwd

/home/hc

3.進入當前目錄的父目錄的父目錄

命令：

cd ../..

輸出：

hc@hc-virtual-machine:~/PycharmProjects$ pwd

/home/hc/PycharmProjects

hc@hc-virtual-machine:~/PycharmProjects$ cd ../..

hc@hc-virtual-machine:/home$ pwd

/home

4. 進入當前用戶主目錄

“當前用戶主目錄”和“系統根目錄”是兩個不同的概念。進入當前用戶主目錄有兩個方法。

命令1：

cd

直接輸入cd，然后回車

輸出：

hc@hc-virtual-machine:~/PycharmProjects/my_test$ pwd

/home/hc/PycharmProjects/my_test

hc@hc-virtual-machine:~/PycharmProjects/my_test$ cd

hc@hc-virtual-machine:~$ pwd

/home/hc

上面的命令是我在非root用戶下操作的，現在我切換到root用戶下再操作一遍

hc@hc-virtual-machine:~/PycharmProjects/my_test$ sudo su

root@hc-virtual-machine:/home/hc/PycharmProjects/my_test# pwd

/home/hc/PycharmProjects/my_test

root@hc-virtual-machine:/home/hc/PycharmProjects/my_test# cd

root@hc-virtual-machine:~# pwd

/root

命令2：

cd ~

輸出

hc@hc-virtual-machine:~/PycharmProjects/my_test$ pwd

/home/hc/PycharmProjects/my_test

hc@hc-virtual-machine:~/PycharmProjects/my_test$ cd ~

hc@hc-virtual-machine:~$ pwd

/home/hc

5. 跳轉到指定目錄

命令

cd /home/hc/PycharmProjects/my_test/

輸出

hc@hc-virtual-machine:/$ pwd

/

hc@hc-virtual-machine:/$ cd /home/hc/PycharmProjects/my_test/

hc@hc-virtual-machine:~/PycharmProjects/my_test$ pwd

/home/hc/PycharmProjects/my_test

6.返回進入此目錄之前所在的目錄

命令：

cd -

說明：自動跳轉到進入此目錄之前所在的目錄，并輸出所在目錄名稱

輸出：

hc@hc-virtual-machine:/$ pwd

/

hc@hc-virtual-machine:/$ cd /home/hc/PycharmProjects/my_test/

hc@hc-virtual-machine:~/PycharmProjects/my_test$ pwd

/home/hc/PycharmProjects/my_test

hc@hc-virtual-machine:~/PycharmProjects/my_test$ cd -

/

hc@hc-virtual-machine:/$ pwd

/

7. 把上個命令的參數作為cd參數使用

命令：

cd !$

輸出:

hc@hc-virtual-machine:~/PycharmProjects/my_test$ pwd

/home/hc/PycharmProjects/my_test

hc@hc-virtual-machine:~/PycharmProjects/my_test$ ls /opt/

google

hc@hc-virtual-machine:~/PycharmProjects/my_test$ cd !$

cd /opt/

hc@hc-virtual-machine:/opt$ pwd

/opt
