.SH DESCRIPTION

present on
|

|
.PP
|
|
.B dumpe2fs
|
|
is similar to Berkeley's
|

.B dumpfs
|

program for the BSD Fast File System.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-b
|
|
print the blocks which are reserved as bad in the filesystem.
|
|
.TP
|
|
.BI \-ob " superblock"
|
|
use the block
|
|
.I superblock
|
|
when examining the filesystem.
|
|
This option is not usually needed except by a filesystem wizard who
|
|
is examining the remains of a very badly corupted filesystem.
|
|
.TP
|
|
.BI \-oB " blocksize"
|
|
use blocks of
|
|
.I blocksize
|
|
bytes when examining the filesystem.
|
|
This option is not usually needed except by a filesystem wizard who
|
|
is examining the remains of a very badly corupted filesystem.
|
|
.TP
|
|
.B \-f
|
|
force dumpe2fs to display a filesystem even though it may have some
|
|
filesystem feature flags which dumpe2fs may not understand (and which
|
|
can cause some of dumpe2fs's display to be suspect).
|
|
.TP
|
|
.B \-h
|
|
only display the superblock information and not any of the block
|
|
group descriptor detail information.
|
|
.TP
|
|
.B \-V
|
|
print the version number of
|
|
.B dumpe2fs
|
|
and exit.
|
|
.SH BUGS
|
|
You need to know the physical filesystem structure to understand the
|
|
output.
