hi how can i find the filesystem on particular device. Ex. I have a device on my Redhat Linux 7.0 /dev/hda1 ... but how can i know which filesystem does it has. Is there any command for this.
regards

Well since most of them are listed in /etc/fstab anyway. I suppose something as simple as the following command could get you a quick answer:

grep /dev/hda1 /etc/fstab | awk '{print $3}'

Or if it's mounted anyway you could do something like:

grep /dev/hda1 /proc/mounts | awk '{print $3}'

If that isn't enough then you would probably have to read the first (or first few sectors) and try to recognize the filesystem type. I think fsck does something like this so you could look into the code to see how it's done there.

You can use following command to see filesystem type: -

file -s /dev/hda*
