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：

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)
