NAME
       readdump	 - Utility to examine dumpfiles	created	by the Coda backup fa-
       cility

SYNOPSIS
       readdump	[dumpfile]

DESCRIPTION
       The readdump program is an interactive facility to allow	 the  user  to
       get information from a dump file	produced by the	Coda backup mechanism.
       For now it is simply a way of looking at	 the  information  in  a  dump
       file. One cannot	use it to modify the dump file.

       The readdump program supports the following commands:

       openDumpFile  <dumpfile>

       showHeader

       showVolumeDiskData

       setIndex	 <index	type>

       nextVnode

       skipVnodes <nVnodes>

       quit

       readdump	 uses the ci command interface,	which allows the use of	unique
       prefixes	for commands. Unspecified parameters will be prompted for, and
       default	values	can  be	 used.	The  showHeader	command	prints out the
       header of the dump, which is seperate from the  header  of  the	volume
       that  was  dumped.  The showVolumeDiskData prints out the header	of the
       volume.

       The dump	contains two streams of	vnodes,	one for	 directories  and  one
       for  files  and symbolic	links. The setIndex command specifies to read-
       dump which stream you wish to examine. Once an index  has  been	speci-
       fied,  the  nextVnode  command  displays	the next Vnode (object)	in the
       stream. Note that movement through the stream  is  one-directional.  To
       revisit	a Vnode, use the setIndex command to reset the program back to
       the beginning of	the stream.  One can jump through the index by use  of
       the  skipVnodes	command, which takes the number	of vnodes to skip, and
       reads past (without displaying) that many vnodes	in the stream.

Future Work
       Usage of	this facility should suggest more commands to help administra-
       tors parse dumpfiles. In	particular, a command to seek ahead to a spec-
       ified offset in the dump	would be useful.
