Is there Any command ?
 

When i provide partition or in Linux if i give something like /dev/sda2 , is there any way to knw the filesystem its using

I mean any command or so , to determine which filesystem is this particular partition using ???

[minh@thanhminh ~]$ sudo /sbin/fdisk -l

Disk /dev/hda: 40.0 GB, 40020664320 bytes
240 heads, 63 sectors/track, 5169 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

Device Boot Start End Blocks Id System
/dev/hda1 1 14 105808+ 83 Linux
/dev/hda2 15 82 514080 82 Linux swap

You can also try 'blkid'.

mount ?

That gives you the partition type---not the filesystem.

I hope it's nothing like "press any key to continue"
"Huh, I can't find the 'any' key?!" ;)

You can also use "sudo file -s /dev/sda1". You can also use "file <imagefile>" for detecting the filesystem of a filesystem image file.

How about cat /etc/fstab.

Yes, if fstab contains the information. If you have a new partition, or the
information in fstab is incorrect, and so it won't mount, you still have some tools that can help.

sudo lshw will give you the file systems in use.

It's list hardware, and it'll give size, extension, mounts, and file structure.

what gives you partition type, guess.

you're stupid
