How do I find filesystem type

sykkn · 08-20-2002, 11:01 AM

Does anyone know of a command that would return the fs type if given the device name.
Example:
===============
# whatfs /dev/hda1
ext3
===============

I know that I can do 'fdisk -l /dev/hda' and I can then look for /dev/hda1, but that complicates
what I am doing. I would appreciate any help.

# cat /proc/mounts | grep /dev/hda1

Try: fsck -N /dev/hda1

Executes and shows the internal command
used to fire up the appropriate file system
checker. Should display something like:

fsck 1.27 (8-Mar-2002)
[/sbin/fsck.ext3 (1) -- /boot] fsck.ext3 /dev/hda1

Shows the fsck version, checker executable, command
number, file system label and the command to start
the checker. I ran this on RedHat 7.3 with my hda1
labeled as /boot and mounted as /boot.

Oh... the file system is ext3. The file system
type for the device is the extension of fsck.xxxx.

and here the type would be ntfs

fsck -N /dev/hda1
fsck 1.24a (02-Sep-2001)
fsck: fsck.ntfs: not found

I see what your trying to do,
maybe an easier way

some variation of this may work

cat /proc/mounts | grep /dev/hda1 | cut -d "a" -f2- | cut -d "/" -f2- | cut -d " " -f2

this returned

ntfs

play around with it
