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.

EXAMPLES

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