20 devdump is a crude utility to interactively display the contents of
21 device or filesystem images. The initial screen is a display of the
22 first 256 bytes of the first 2048 byte sector. The commands are the
23 same as with isodump.
24
25 isodump is a crude utility to interactively display the contents of
26 iso9660 images in order to verify directory integrity. The initial
27 screen is a display of the first part of the root directory, and the
28 prompt shows you the extent number and offset in the extent.
29
30 You can use the 'a' and 'b' commands to move backwards and for‐
31 wards within the image. The 'g' command allows you to goto an
32 arbitrary extent, and the 'f' command specifies a search string
33 to be used. The '+' command searches forward for the next
34 instance of the search string, and the 'q' command exits devdump
35 or isodump.
36
37 isoinfo is a utility to perform directory like listings of iso9660
38 images.
39
40 isovfy is a utility to verify the integrity of an iso9660 image. Most
41 of the tests in isovfy were added after bugs were discovered in early
42 versions of genisoimage. It isn't all that clear how useful this is
43 anymore, but it doesn't hurt to have this around.
44
45
47 The options common to all programs are -help,-h,-version,
48 i=name,dev=name. The isoinfo program has additional command line
49 options. The options are:
50
51 -help
52
53 -h print a summary of all options.
54
55 -d Print information from the primary volume descriptor (PVD) of
56 the iso9660 image. This includes information about Rock Ridge,
57 Joliet extensions and Eltorito boot information if present.
58
59 -f generate output as if a 'find . -print' command had been run on
60 the iso9660 image. You should not use the -l image with the -f
61 option.
62
63 -i iso_image
64 Specifies the path of the iso9660 image that we wish to examine.
65 The options -i and dev=target are mutual exclusive.
66
67 dev=target
68 Sets the SCSI target for the drive, see notes above. A typical
69 device specification is dev=6,0 . If a filename must be pro‐
70 vided together with the numerical target specification, the
71 filename is implementation specific. The correct filename in
72 this case can be found in the system specific manuals of the
73 target operating system. On a FreeBSD system without CAM sup‐
74 port, you need to use the control device (e.g. /dev/rcd0.ctl).
75 A correct device specification in this case may be
76 dev=/dev/rcd0.ctl:@ .
77
78 On Linux, drives connected to a parallel port adapter are mapped
79 to a virtual SCSI bus. Different adapters are mapped to differ‐
80 ent targets on this virtual SCSI bus.
81
82 If no dev option is present, the program will try to get the
83 device from the CDR_DEVICE environment.
84
85 If the argument to the dev= option does not contain the charac‐
86 ters ',', '/', '@' or ':', it is interpreted as an label name
87 that may be found in the file /etc/wodim.conf (see FILES sec‐
88 tion).
89
90 The options -i and dev=target are mutual exclusive.
91
92 -l generate output as if a 'ls -lR' command had been run on the
93 iso9660 image. You should not use the -f image with the -l
94 option.
95
96 -N sector
97 Quick hack to help examine single session disc files that are to
98 be written to a multi-session disc. The sector number specified
99 is the sector number at which the iso9660 image should be writ‐
100 ten when send to the cd-writer. Not used for the first session
101 on the disc.
102
103 -p Print path table information.
104
105 -R Extract information from Rock Ridge extensions (if present) for
106 permissions, file names and ownerships.
107
108 -J Extract information from Joliet extensions (if present) for file
109 names.
110
111 -j charset
112 Convert Joliet file names (if present) to the supplied charset.
113 See genisoimage(8) for details.
114
115 -T sector
116 Quick hack to help examine multi-session images that have
117 already been burned to a multi-session disc. The sector number
118 specified is the sector number for the start of the session we
119 wish to display.
120
121 -x pathname
122 Extract specified file to stdout.

126 <ericy@gnu.ai.mit.edu> or <eric@andante.jic.com> is to blame for these
127 shoddy hacks. Joerg Schilling wrote the SCSI transport library and
128 it's adaptation layer to the programs and newer parts (starting from
129 1999) of the utilities, this makes them Copyright (C) 1999-2004 Joerg

131 accepted.

133 This manpage describes the program implementation of isoinfo as shipped
134 by the cdrkit distribution. See http://alioth.debian.org/projects/deb‐
135 burn/ for details. It is a spinoff from the original program distrib‐
136 uted in the cdrtools package [1]. However, the cdrtools developers are
137 not involved in the development of this spinoff and therefore shall not
138 be made responsible for any problem caused by it. Do not try to get
139 support for this program by contacting the original author(s).
140
141 If you have support questions, send them to
142
143 debburn-devel@lists.alioth.debian.org
144
145 If you have definitely found a bug, send a mail to this list or to
146
147 submit@bugs.debian.org
148
149 writing at least a short description into the Subject and "Package:
150 cdrkit" into the first line of the mail body.
151
153 The user interface really sucks.
154
156 These utilities are really quick hacks, which are very useful for
157 debugging problems in genisoimage or in an iso9660 filesystem. In the
158 long run, it would be nice to have a daemon that would NFS export a
159 iso9660 image.
160
161 The isoinfo program is probably the program that is of the most use to
162 the general user.
163
165 These utilities come with the cdrkit package, and the primary download
166 site is http://debburn.alioth.debian.org/ and FTP mirrors of distribu‐
167 tions. Despite the name, the software is not beta.
168
169
171 CDR_DEVICE
172 This may either hold a device identifier that is suitable to the
173 open call of the SCSI transport library or a label in the file
174 /etc/wodim.conf.
175
176 RSH If the RSH environment is present, the remote connection will
177 not be created via rcmd(3) but by calling the program pointed to
178 by RSH. Use e.g. RSH=/usr/bin/ssh to create a secure shell
179 connection.
180
181 Note that this forces the program to create a pipe to the rsh(1)
182 program and disallows the program to directly access the network
183 socket to the remote server. This makes it impossible to set up
184 performance parameters and slows down the connection compared to
185 a root initiated rcmd(3) connection.
186
187 RSCSI If the RSCSI environment is present, the remote SCSI server will
188 not be the program /opt/schily/sbin/rscsi but the program
189 pointed to by RSCSI. Note that the remote SCSI server program
190 name will be ignored if you log in using an account that has
191 been created with a remote SCSI server program as login shell.
192
193
195 /etc/wodim.conf
196 Default values can be set for the following options in
197 /etc/wodim.conf.
198
199 CDR_DEVICE
200 This may either hold a device identifier that is suitable
201 to the open call of the SCSI transport library or a label
202 in the file /etc/wodim.conf that allows to identify a
203 specific drive on the system.
204
205 Any other label
206 is an identifier for a specific drive on the system.
207 Such an identifier may not contain the characters ',',
208 '/', '@' or ':'.
209
210 Each line that follows a label contains a TAB separated
211 list of items. Currently, four items are recognized: the
212 SCSI ID of the drive, the default speed that should be
213 used for this drive, the default FIFO size that should be
214 used for this drive and drive specific options. The val‐
215 ues for speed and fifosize may be set to -1 to tell the
216 program to use the global defaults. The value for
217 driveropts may be set to "" if no driveropts are used. A
218 typical line may look this way:
219
220 teac1= 0,5,0 4 8m ""
221
222 yamaha= 1,6,0 -1 -1 burnfree
223
224 This tells the program that a drive named teac1 is at
225 scsibus 0, target 5, lun 0 and should be used with speed
226 4 and a FIFO size of 8 MB. A second drive may be found
227 at scsibus 1, target 6, lun 0 and uses the default speed
228 and the default FIFO size.
