jcat man page

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.

Examples

jcat -f linux-ext3 img.dd 34 | xxd
