linux 查看文件系统类型

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)
:~$

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 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
:~$

3. fdisk

:~$ sudo fdisk /dev/sda
WARNING: DOS-compatible mode is deprecated. It"s strongly recommended to
switch off the mode (command “c”) and change display units to
sectors (command “u”).
Command (m for help): c

4. 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
kysnail@ubunkysnail:~$ sudo file -s /dev/sda1
/dev/sda1: Linux rev 1.0 ext4 filesystem data, UUID=4942da40-8a49-4bfd-9dc2-45c906d48413 (needs journal recovery) (extents) (large files) (huge files)
:~$

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.
(parted) p
Model: VMware, VMware Virtual S (scsi)
磁盘 /dev/sda: 21.5GB
Sector size (logical/physical): 512B/512B

5 20.5GB 21.5GB 938MB logical linux-swap(v1)
(parted)

6. 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
   /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0
