NAME


jcat - Show the contents of a block in the file system journal.

SYNOPSIS


jcat [-f fstype ] [-vV] [-i imgtype] [-o imgoffset] [-b dev_sector_size] image [images] ]
[ inode ] jblk

DESCRIPTION


jcat shows the contents of a journal block in the file system journal. The inode address
of the journal can be given or the default location will be used. Note that the block
address is a journal block address and not a file system block. The raw output is given
to STDOUT.

ARGUMENTS


-f fstype
Specify the file system type. Use '-f list' to list the supported file system
types. If not given, autodetection methods are used.

-i imgtype
Identify the type of image file, such as raw. Use '-i list' to list the supported
types. If not given, autodetection methods are used.

-o imgoffset
The sector offset where the file system starts in the image.

-b dev_sector_size
The size, in bytes, of the underlying device sectors. If not given, the value in
the image format is used (if it exists) or 512-bytes is assumed.

-V Display version

-v verbose output

image [images]
The disk or partition image to read, whose format is given with '-i'. Multiple
image file names can be given if the image is split into multiple segments. If
only one image file is given, and its name is the first in a sequence (e.g., as
indicated by ending in '.001'), subsequent image segments will be included
automatically.

[inode]
The inode where the file system journal can be found.

jblk The journal block to display.
