NAME    [Toc]    [Back]

       shblk  -  Displays disk blocks, as unformatted hexadecimal

SYNOPSIS    [Toc]    [Back]

       /sbin/advfs/shblk [-sb start_block] [-bc block_count] special

OPTIONS    [Toc]    [Back]

       Specifies the block on which to start.  Specifies the number
 of blocks to display.

OPERANDS    [Toc]    [Back]

       Specifies the device special file for the volume on  which
       the  block(s)  are  located. You can specify the volume by
       either its character or block device special file name.

              If you are executing the  command  from  the  mount
              point  for the volume, you must specify the character
 device special file, as  specifying  the  block
              device special file produces a device busy error.

DESCRIPTION    [Toc]    [Back]

       The shblk command displays the selected blocks as hexadecimal
 numbers.  The blocks are not formatted to any data or
       metadata representation.

       You must be the root user to use this command.

EXAMPLES    [Toc]    [Back]

       The following example shows a user whose current file system
 is mounted on /dev/disk/dsk3a  attempting  to  display
       block  1  of  the  a  partition on that device.  Using the
       block device special file for the command does  not  work;
       using  the  character  device special file does work.  The
       display is truncated on the right due to page width  limitations:
  #  /sbin/advfs/shblk -sb 1 -bc 1 /dev/disk/dsk3a
       open:  Device  busy  #  /sbin/advfs/shblk  -sb  1  -bc   1
