| -g cylinder_group |
| | This restricts the dump to information about this cylinder group only. Here 0 means the first cylinder group and -1 the last one. |
| -i inode |
| | This restricts the dump to information about this particular inode only. Here the minimum acceptable inode is 2. If this option is omitted but a cylinder group is defined then only inodes within that cylinder group are dumped. |
| -l level |
| | The level of detail which will be dumped. This value defaults to 255 and is the "bitwise or" of the following table: |
| 0x001 | initial superblock |
| 0x002 | superblock copies in each cylinder group |
| 0x004 | cylinder group summary in initial cylinder group |
| 0x008 | cylinder group information |
| 0x010 | inode allocation bitmap |
| 0x020 | fragment allocation bitmap |
| 0x040 | cluster maps and summary |
| 0x100 | inode information |
| 0x200 | indirect block dump |
