shblk

shblk(8)						      System Manager's Manual							  shblk(8)

NAME

       shblk - Displays disk blocks, as unformatted hexadecimal numbers

SYNOPSIS

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

OPTIONS

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

OPERANDS

       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  speci-
	      fying the block device special file produces a device busy error.

DESCRIPTION

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

       You must be the root user to use this command.

EXAMPLES

       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 /dev/rdisk/dsk3a
