| 38 | use the block |
| 39 | .I superblock |
| 40 | when examining the filesystem. |
| Theodore Ts'o | 02e7dd9 | 1999-06-18 00:48:41 +0000 | [diff] [blame] | 41 | This option is not usually needed except by a filesystem wizard who |
| 42 | is examining the remains of a very badly corupted filesystem. |

| Theodore Ts'o | caf8ce4 | 1999-10-21 19:56:34 +0000 | [diff] [blame] | 44 | .BI \-oB " blocksize" |

| 53 | filesystem feature flags which dumpe2fs may not understand (and which |
| 54 | can cause some of dumpe2fs's display to be suspect). |
