File system format for viewing disk partitions under Linux

Df-t can only view the partitions and file system types that are already mounted.

Filesystem Type 1k-blocks used Available use% mounted on
/DEV/SDA1 ext4 20642428 3698868 15894984 19%/
Tmpfs Tmpfs 32947160 0 32947160 0%/dev/shm

Fdisk-l can display all mounted and non-mounted partitions, but does not display the file system type.
