linux 查看文件系统类型  
Linux 查看文件系统的方式有多种，列举如下：

1.  mount
    
        :~$ mount
         /dev/sda1 on / type ext4 (rw,errors=remount-ro,user_xattr)
         proc on /proc type proc (rw,noexec,nosuid,nodev)
         none on /sys type sysfs (rw,noexec,nosuid,nodev)
         none on /sys/fs/fuse/connections type fusectl (rw)
         none on /sys/kernel/debug type debugfs (rw)
         none on /sys/kernel/security type securityfs (rw)
         none on /dev type devtmpfs (rw,mode=0755)
         none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
         none on /dev/shm type tmpfs (rw,nosuid,nodev)
         none on /var/run type tmpfs (rw,nosuid,mode=0755)
         none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
         none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
         none on /var/lib/ureadahead/debugfs type debugfs (rw,relatime)
         none on /proc/fs/vmblock/mountPoint type vmblock (rw)
         binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
         gvfs-fuse-daemon on /home/kysnail/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=kysnail)
         :~$
2.  df
    
        :~$ df -lhT
         文件系统      类型    容量  已用 可用 已用% 挂载点
         /dev/sda1     ext4     19G   11G  7.8G  57% /
         none      devtmpfs    498M  248K  497M   1% /dev

         none         tmpfs    502M     0  502M   0% /var/lock
         none         tmpfs    502M     0  502M   0% /lib/init/rw
         none       debugfs     19G   11G  7.8G  57% /var/lib/ureadahead/debugfs
         :~$
3.  fdisk
    
        :~$ sudo fdisk /dev/sda

4.  file
    
        :~$ sudo file -s /dev/sda

         :~$
5.  parted
    
        :~$ sudo parted
         GNU Parted 2.2
         使用 /dev/sda
         欢迎使用 GNU Parted! 输入 "help"可获得命令列表.

6.  查看 fstab

         # devices that works even if disks are added and removed. See fstab(5).
