Identify File System of your Linux Machine

There are four hot way through which you can identify the File system of your Linux Machine. Lets go through them one by one.

Note: My Linux Machine is Mounted on /dev/sda5

1. Using fsck command

$ sudo fsck -N /dev/sda5
fsck from util-linux 2.20.1
[/sbin/fsck.ext4 (1) -- /] fsck.ext4 /dev/sda5

2. Using file Command

$ sudo file -sL /dev/sda5
/dev/sda5: Linux rev 1.0 ext4 filesystem data, UUID=04c34a8e-1daa-415a-8df4-c5bbf1ae9648 (needs journal recovery) (extents) (large files) (huge files)

3. Using mount command

$ sudo mount | grep -i "^/dev"
/dev/sda5 on / type ext4 (rw,errors=remount-ro)

Note: Above command shows only those line which are starting from /dev.

4. By checking /etc/fstab file

$ sudo tail -4 /etc/fstab
# / was on /dev/sda5 during installation
UUID=04c34a8e-1daa-415a-8df4-c5bbf1ae9648 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda6 during installation
UUID=b81848da-b542-42f8-a638-b125dfcb2dbd none swap sw 0 0
