    You can also check it by df -T

    Sample output:

    Filesystem    Type   1K-blocks      Used Available Use% Mounted on
/dev/hdb1     ext3    19228276  14737848   3513680  81% / 
tmpfs        tmpfs      383960         4    383956   1% /dev/shm

    You can also try df -hT

    From man df:

    -h, --human-readable
              print sizes in human readable format (e.g., 1K 234M 2G)
-T, --print-type
              print file system type

  2. Just type mount, it will show all mounted devices and what fs type they are mounted as.

  3. You could also do a sudo fdisk -l

    nits@nits-excalibur:~$ sudo fdisk -l

Partition table entries are not in disk order

    sudo blkid gives you information about the format of the partition along with its UUID and label if any.

    nits@nits-excalibur:~$ sudo blkid
[sudo] password for nits: 
/dev/sda1: LABEL="System Reserved" UUID="22F2DE0DF2DDE4D7" TYPE="ntfs" 
/dev/sda2: UUID="6E5E0E255E0DE6A5" TYPE="ntfs" 
/dev/sda4: LABEL="TestDrive" UUID="e6e47b0b-4c88-43f9-9165-81b2c1af4d1c" TYPE="ext4" 
/dev/sda5: LABEL="Storage_1" UUID="42DC637EDC636B5D" TYPE="ntfs" 
/dev/sda6: LABEL="Storage_2" UUID="D890877C9087603C" TYPE="ntfs" 
/dev/sda7: UUID="b73e274d-fdb2-45ac-acfe-9fcb48631ff7" TYPE="ext4" 
/dev/sda8: UUID="831304eb-1ee5-486c-a4a4-ef40b6c2d4dc" TYPE="ext4" 
/dev/sda9: UUID="9ba518d1-4a03-4b92-9b31-15db045c8cd4" TYPE="ext4" 
/dev/sda10: UUID="dcc15cd3-041d-4ad2-915e-9c0dae9310c7" TYPE="ext4" 
/dev/sda11: UUID="3ad60b50-a4f3-4dff-b62e-610766e1b119" TYPE="ext4" 
/dev/sda12: UUID="5604929a-9d9e-4ab0-907f-b9479a3b55e5" TYPE="swap"

    The two commands in conjunction with each other should be enough to get the information about partitions on your system.

  4. If you want to know what filesystem types are supported by your kernel, 

    cat /proc/filesystems
