8、查看fstab文件
这个文件定义了各硬盘分区挂载到的目录路径。
方法：cat fstab
显示：# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda8 during installation
UUID=bb6033ba-9396-445d-8e0c-9c3a3b7561f7 / ext4 errors=remount-ro 0 1
# /home was on /dev/sda11 during installation
UUID=f9d552e4-9377-4116-8949-dd2031bb37f1 /home ext4 defaults 0 2
# /my_space was on /dev/sda14 during installation

# /var was on /dev/sda10 during installation
UUID=0a6e208f-db99-4320-a9c6-22328e2d1c56 /var ext4 defaults 0 2
# swap was on /dev/sda13 during installation
UUID=a030a3c7-5ff1-4ad7-a7c8-c0bd81b8d954 none swap sw 0 0
9、查看以b开头的文件
方法：cat b<TAB><TAB>
显示：cat: 'b<TAB><TAB>': No such file or directory
方法：ca<TAB><TAB>
显示：cat: 'b<TAB><TAB>': No such file or directory
10、查看以p或c结尾的文件

12、显示当前目录
方法：pwd
显示：/etc
13、改变目录
方法：cd
显示：wyx@wys-pc:~$
14、列目录
目录后面加/，可执行文件后面加*，链接文件后面加@
方法：ls -F
显示：Desktop/ Downloads/ hello.c Pictures/ Templates/ Videos/
Documents/ examples.desktop Music/ Public/ test*
列出包含隐藏文件在内的所有文件，并以参数-F形式显示
