What will happen if execute dumpe2fs on a ms dos file system?

Linux

Executing dumpe2fs on an MS-DOS file system will result in an error because dumpe2fs is specifically designed for ext2/ext3/ext4 file systems used in Linux. Since MS-DOS uses a different file system structure (FAT12, FAT16, FAT32), dumpe2fs will not recognize the format and will likely return a message indicating that it cannot read the file system or that it is not a valid ext filesystem. Essentially, the command will be ineffective for MS-DOS file systems.
