14 The readdump program is an interactive facility to allow the user to
15 get information from a dump file produced by the Coda backup mechanism.
16 For now it is simply a way of looking at the information in a dump
17 file. One cannot use it to modify the dump file.
18
19 The readdump program supports the following commands:
20
21 openDumpFile <dumpfile>
22
23 showHeader
24
25 showVolumeDiskData
26
27 setIndex <index type>
28
29 nextVnode
30
31 skipVnodes <nVnodes>
32
33 quit
34
35 readdump uses the ci command interface, which allows the use of unique
36 prefixes for commands. Unspecified parameters will be prompted for, and
37 default values can be used. The showHeader command prints out the
38 header of the dump, which is seperate from the header of the volume
39 that was dumped. The showVolumeDiskData prints out the header of the
40 volume.
41
42 The dump contains two streams of vnodes, one for directories and one
43 for files and symbolic links. The setIndex command specifies to read‐
44 dump which stream you wish to examine. Once an index has been speci‐
45 fied, the nextVnode command displays the next Vnode (object) in the
46 stream. Note that movement through the stream is one-directional. To
47 revisit a Vnode, use the setIndex command to reset the program back to
48 the beginning of the stream. One can jump through the index by use of
49 the skipVnodes command, which takes the number of vnodes to skip, and
50 reads past (without displaying) that many vnodes in the stream.
51
53 Usage of this facility should suggest more commands to help administra‐
54 tors parse dumpfiles. In particular, a command to seek ahead to a spec‐
55 ified offset in the dump would be useful.
