linux下查看磁盘分区的文件系统格式

df -T 只可以查看已经挂载的分区和文件系统类型。

[root@bogon ~]# df -T |sort
/dev/sda1      xfs         201380  110156     91224  55% /boot

tmpfs          tmpfs       999004    8728    990276   1% /run

fdisk -l 可以显示出所有挂载和未挂载的分区，但不显示文件系统类型。

[root@bogon ~]# fdisk -l

parted -l 可以查看未挂载的文件系统类型，以及哪些分区尚未格式化。

[root@bogon ~]# parted -l

lsblk -f 也可以查看未挂载的文件系统类型。

[root@bogon ~]# lsblk -f
