# blkstat(1)

Display details of a file system data unit (i.e. block or sector)

## NAME

blkstat - Display details of a file system data unit (i.e. block or sector)

## SYNOPSIS

**blkstat \[-f** *fstype* **\] \[-i imgtype\] \[-o imgoffset\] \[-b dev\_sector\_size\] \[-vV\]** *image \[images\] addr*

## DESCRIPTION

**blkstat** displays the allocation status of the given data unit. **blkstat** was called  **dstat** in TSK versions prior to 3.0.0.

## 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

  Verbose output of debugging statements to stderr

- \-V

  Display version

- 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.

- addr

  Address to display stats on.  This is a fragment for UNIX file systems or a sector for FAT.
