Linux file system can be partitioned with various partition formats. We call it as file system types. Some of the file system types are listed below.

  • ext2
  • ext3
  • ext4
  • jfs
  • ReiserFS
  • XFS
  • Btrfs

Inorder to identify the type of file system in an already existing Linux OS, we can use one of the below approaches.

Approach 1: Using lsblk command

Issue the following command. It will display the file system types and the mount points

lsblk -f

Approach 2: Using blkid command
