linux dumpe2fs

dumpe2fs is a command-line utility in Linux used to display information about an ext2, ext3, or ext4 filesystem. It provides detailed information about the filesystem, such as block size, inode count, file system features, and more.

To use dumpe2fs, you need to specify the device or partition where the filesystem is located. Here's an example command:

dumpe2fs /dev/sda1

Replace `/dev/sda1` with the appropriate device or partition for your system. Running this command will display various details about the filesystem on that device or partition.

Please note that dumpe2fs requires superuser (root) privileges to access the filesystem directly. So, you may need to run it with sudo or as the root user.
