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

1. :~$ mount
2. /dev/sda1 on / type ext4 (rw,errors=remount-ro,user_xattr)
3. proc on /proc type proc (rw,noexec,nosuid,nodev)
4. none on /sys type sysfs (rw,noexec,nosuid,nodev)
5. none on /sys/fs/fuse/connections type fusectl (rw)
6. none on /sys/kernel/debug type debugfs (rw)
7. none on /sys/kernel/security type securityfs (rw)
8. none on /dev type devtmpfs (rw,mode=0755)
9. none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
10. none on /dev/shm type tmpfs (rw,nosuid,nodev)
11. none on /var/run type tmpfs (rw,nosuid,mode=0755)
12. none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
13. none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
14. none on /var/lib/ureadahead/debugfs type debugfs (rw,relatime)
15. none on /proc/fs/vmblock/mountPoint type vmblock (rw)
16. binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
17. gvfs-fuse-daemon on /home/kysnail/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=kysnail)
18. :~$

6. 查看 fstab

1. # /etc/fstab: static file system information.
2. #
3. # Use "blkid -o value -s UUID" to print the universally unique identifier
4. # for a device; this may be used with UUID= as a more robust way to name
5. # devices that works even if disks are added and removed. See fstab(5).
6. #
7. # <file system> <mount point>   <type>  <options>       <dump>  <pass>
8. proc            /proc           proc    nodev,noexec,nosuid 0       0
9. # / was on /dev/sda1 during installation
10. UUID=4942da40-8a49-4bfd-9dc2-45c906d48413 /               ext4    errors=remount-ro,user_xattr 0       1
11. # swap was on /dev/sda5 during installation
