How to find the partition types in linux

How do we find the partition type in Linux? df -T will give me the mounted partition types like ufs, ext3 etc. How do I find out for say a newly added disk to the system? Please advise...

Thanks

You could try fdisk -l. This won't be a lot of help if it contains Linux partitions, since almost every linux partition falls under the umbrella of a type-83 "linux" partition(and linux basically ignores that field anyway, treating it as nothing but a label.) But NTFS partitions will show as HPFS/NTFS, DOS as FAT16 or FAT32, and so forth.

If they're linux partitions, try mounting them somewhere as read-only. The kernel can often autodetect their type on mount.

fsck -N (fsck -V in some systems) can also give you some pointers:

This is what I get in a RHEL system:

Code:
[root@nix ~]# fsck -N /dev/sdc2
fsck from util-linux-ng 2.17.2
[/sbin/fsck.ext4 (1) -- /boot] fsck.ext4 /dev/sdc2
