2，dir 切換當前目錄至dirName
cd/cd~ 回到用戶主目錄 cd / 進入系統根目錄 cd - 返回進入此目錄之前所在目錄[ligang@centos6 test4]$ cd / [ligang@centos6 /]$ cd [ligang@centos6 ~]$ [root@localhost soft]# pwd /opt/soft [root@localhost soft]# cd - /root [root@localhost ~]# pwd /root [root@localhost ~]# cd - /opt/soft [root@localhost soft]#3，pwd pwd 命令來查看”當前工作目錄“的完整路徑 pwd顯示的是連接路徑 pwd -P 顯示出實際路徑 /bin/pwd 選項
[ligang@centos6 init.d]$ pwd /etc/init.d [ligang@centos6 init.d]$ /bin/pwd /etc/rc.d/init.d [ligang@centos6 init.d]$ pwd /etc/init.d [ligang@centos6 init.d]$ pwd -L /etc/init.d [ligang@centos6 init.d]$ pwd -P /etc/rc.d/init.d
