What file system do I have installed?
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
Just type mount, it will show all mounted devices and what fs type they are mounted as.
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.

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