inux 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)  
:~$

1.  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 252K 501M 1% /dev/shm  
none tmpfs 502M 96K 502M 1% /var/run  
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  
:~$

1.  fdisk

:~$ sudo fdisk /dev/sda

switch off the mode (command “c”) and change display units to  
sectors (command “u”).

1.  file

:~$ sudo file -s /dev/sda  
/dev/sda: x86 boot sector; partition 1: ID=0x83, active, starthead 32, startsector 2048, 40103936 sectors; partition 2: ID=0x5, starthead 254, startsector 40108030, 1832962 sectors, code offset 0x63

:~$

1.  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.

1.  查看 fstab
    
    \#/etc/fstab: static file system information.
    
    ##  ##
    
    \#Use “blkid -o value -s UUID” 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>  
    proc /proc proc nodev,noexec,nosuid 0 0  
    \#/ was on /dev/sda1 during installation  
    UUID=4942da40-8a49-4bfd-9dc2-45c906d48413 / ext4 errors=remount-ro,user\_xattr 0 1  
    \#swap was on /dev/sda5 during installation  
    UUID=935fb95d-771f-448e-9d23-4820106e1783 none swap sw 0 0
