linux 查看文件系统类型

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  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

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

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

    :~$
   

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

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).
    #
