The same files are seen as HFS files when +accessed from a Macintosh and as ISO9660 files when accessed from other +machines. HFS stands for +.I Hierarchical File System +and is the native filesystem used on Macintosh computers. +.PP +As an alternative, +.B genisoimage +can generate the +.I Apple Extensions to ISO9660 +for each file. These extensions provide each file with CREATOR, TYPE and +certain Finder flags when accessed from a Macintosh. See the +.B HFS MACINTOSH FILE FORMATS +section below. +.PP +.B genisoimage +takes a snapshot of a given directory tree, and generates a +binary image which will correspond to an ISO9660 and/or HFS filesystem when +written to a block device. +.PP +Each file written to the ISO9660 filesystem must have a filename in the 8.3 +format (up to 8 characters, period, up to 3 characters, all uppercase), even +if Rock Ridge is in use. This filename is used on systems that are not able +to make use of the Rock Ridge extensions (such as MS-DOS), and each filename +in each directory must be different from the other filenames in the same +directory. +.B genisoimage +generally tries to form correct names by forcing the Unix filename to +uppercase and truncating as required, but often this yields unsatisfactory +results when the truncated names are not all unique. +.B genisoimage +assigns weightings to each filename, and if two names that are otherwise the +same are found, the name with the lower priority is renamed to include a +3-digit number (guaranteed to be unique). For example, the two files +.I foo.bar +and +.I foo.bar.~1~ +could be rendered as +.I FOO.BAR;1 +and +.IR FOO000.BAR;1 . +.PP +When used with various HFS options, +.B genisoimage +will attempt to recognise files stored in a number of Apple/Unix file formats +and will copy the data and resource forks as well as any +relevant Finder information. See the +.B HFS MACINTOSH FILE FORMATS +section below for more about formats +.B genisoimage +supports. +.PP +Note that +.B genisoimage +is not designed to communicate with the writer directly. Most writers +have proprietary command sets which vary from one manufacturer to +another, and you need a specialized tool to actually burn the disc. +.B wodim +is one such tool. The latest version of +.B wodim +is available from +.IR http://www.cdrkit.org/ . +.PP +.B pathspec +is the path of the directory tree to be copied into the ISO9660 filesystem. +Multiple paths can be specified, and +.B genisoimage +will merge the files found in all of the specified path components to +form the filesystem image. +.PP +If the option +.B \-graft\-points +has been specified, it is possible to graft the paths at points other +than the root directory, and it is possible to graft files or +directories onto the cdrom image with names different than what they +have in the source filesystem. This is easiest to illustrate with a +couple of examples. Let's start by assuming that a local file +.I ../old.lis +exists, and you wish to include it in the cdrom image. +.IP +foo/bar/=../old.lis +.PP +will include +.I old.lis +in the cdrom image at +.IR /foo/bar/old.lis , +while +.IP +foo/bar/xxx=../old.lis +.PP +will include +.I old.lis +in the cdrom image at +.IR /foo/bar/xxx . +The same sort of syntax can be used with directories as well. +.B genisoimage +will create any directories required such that the graft +points exist on the cdrom image \(em the directories do not need to +appear in one of the paths. By default, any directories that are created on +the fly like this will have permissions 0555 and appear to be owned by the +person running +.BR genisoimage . +If you wish other permissions or owners of +the intermediate directories, see +.BR \-uid ", " \-gid ", " \-dir\-mode ", " \-file\-mode " and " \-new\-dir\-mode . +.PP +.B genisoimage +will also run on Windows machines when compiled with Cygnus' cygwin +(available from +.IR http://www.cygwin.com/ ). +Therefore most references in this man page to +.I Unix +can be replaced with +.IR Win32 . +.\" ---------------------------------------- +.SH OPTIONS +.PP +Several options can be specified as defaults in a +.I .genisoimagerc +configuration file, as well as on the command line.

For example: +.sp + genisoimage \-o rom \-m \(aq*.o\(aq \-m core \-m foobar +.sp +would exclude all files ending in `.o', or called +.IR core " or " foobar +from the image. Note that if you had a directory called +.IR foobar , +it too (and of course all its descendants) would be excluded. +.TP +.BI \-exclude\-list " file" +A file containing a list of shell wildcards to be excluded. See +.BR \-m . +.TP +.B \-max\-iso9660\-filenames +Allow ISO9660 filenames to be up to 37 characters long. +This option enables +.B \-N +as the extra name space is taken from the space reserved for +file version numbers. +.br +This violates the ISO9660 standard, but it happens to work on many systems. +Although a conforming application needs to provide a buffer space of at +least 37 characters, discs created with this option may cause a buffer +overflow in the reading operating system.

This list +of pathspecs are processed after any that appear on the command line. If the +argument is +.IR \- , +the list is read from the standard input. +.TP +.B \-P +Outdated option; use +.B \-publisher +instead. +.TP +.BI \-publisher " publisher_id" +Specifies a text string that will be written into the volume header. +This should describe the publisher of the CD-ROM, usually with a +mailing address and phone number. There is space for 128 characters. +Equivalent to +.B PUBL +in the +.I .genisoimagerc +file. +.TP +.BI \-p " preparer_id" +Specifies a text string that will be written into the volume header. +This should describe the preparer of the CD-ROM, usually with a mailing +address and phone number. There is space for 128 characters. +Equivalent to +.B PREP +in the +.I .genisoimagerc +file. +.TP +.B \-print\-size +Print estimated filesystem size in multiples of the sector size (2048 bytes) +and exit. This option is needed for +Disk At Once mode and with some CD-R drives when piping directly into +.BR wodim , +cases where +.B wodim +needs to know the size of the filesystem image in advance. +Old versions of +.B mkisofs +wrote this information (among other information) to +.IR stderr . +As this turns out to be hard to parse, the number without any other information +is now printed on +.I stdout +too. +If you like to write a simple shell script, redirect +.I stderr +and catch the number from +.IR stdout . +This may be done with: +.sp + cdblocks=\` genisoimage \-print\-size \-quiet .\|.\|. \` +.br + genisoimage .\|.\|. | wodim .\|.\|. tsize=${cdblocks}s \- +.TP +.B \-quiet +This makes +.B genisoimage +even less verbose. No progress output will be provided. +.TP +.B \-R +Generate SUSP and RR records using the Rock Ridge protocol to further describe +the files on the ISO9660 filesystem. +.TP +.B \-r +This is like the \-R option, but file ownership and modes are set to +more useful values. The uid and gid are set to zero, because they are +usually only useful on the author's system, and not useful to the +client. All the file read bits are set true, so that files and +directories are globally readable on the client. If any execute bit is +set for a file, set all of the execute bits, so that executables are +globally executable on the client. If any search bit is set for a +directory, set all of the search bits, so that directories are globally +searchable on the client. All write bits are cleared, because the +filesystem will be mounted read-only in any case. If any of the special +mode bits are set, clear them, because file locks are not useful on a +read-only filesystem, and set-id bits are not desirable for uid 0 or +gid 0. +When used on Win32, the execute bit is set on +.I all +files. This is a result of the lack of file permissions on Win32 and the +Cygwin POSIX emulation layer. See also +.BR \-uid ", " \-gid , +.BR \-dir\-mode ", " \-file\-mode +and +.BR \-new\-dir\-mode . +.TP +.B \-relaxed\-filenames +Allows ISO9660 filenames to include all 7-bit ASCII characters except +lowercase letters. +.br +This violates the ISO9660 standard, but it happens to work on many systems. +Use with caution. +.TP +.BI \-root " dir" +Moves all files and directories into +.I dir +in the image. This is essentially the +same as using +.B \-graft\-points +and adding +.I dir +in front of every pathspec, but is easier to use. +.I dir +may actually be several levels deep. It is +created with the same permissions as other graft points. +.TP +.BI \-old-root " dir" +This option is necessary when writing a multisession +image and the previous (or even older) session was written with +.B -root +.IR dir . +Using a directory name not found in the previous session +causes +.B genisoimage +to abort with an error. +Without this option, +.B genisoimage +would not be able to find unmodified files and would +be forced to write their data into the image once more. +.B \-root +and +.B \-old-root +are meant to be used together to do incremental backups. +The initial session would e.g. use: +.B genisoimage \-root backup_1 +.IR dirs . +The next incremental backup with +.B genisoimage \-root backup_2 \-old-root backup_1 +.I dirs +would take another snapshot of these directories. The first +snapshot would be found in +.BR backup_1 , +the second one in +.BR backup_2 , +but only modified or new files need to be written +into the second session. +Without these options, new files would be added and old ones would be +preserved. But old ones would be overwritten if the file was +modified. Recovering the files by copying the whole directory back +from CD would also restore files that were deleted +intentionally. Accessing several older versions of a file requires +support by the operating system to choose which sessions are to be +mounted. +.TP +.BI \-sort " sort_file" +Sort file locations on the media. Sorting is controlled by a file that +contains pairs of filenames and sorting offset weighting. +If the weighting is higher, the file will be located closer to the +beginning of the media, if the weighting is lower, the file will be located +closer to the end of the media. There must be only one space or tabs +character between the filename and the +weight and the weight must be the last characters on a line. The filename +is taken to include all the characters up to, but not including the last +space or tab character on a line. This is to allow for space characters to +be in, or at the end of a filename. +This option does +.B not +sort the order of the filenames that appear +in the ISO9660 directory. It sorts the order in which the file data is +written to the CD image, which is useful in order to optimize the +data layout on a CD. See +.B README.sort +for more details. +.TP +.BI \-sparc\-boot " img_sun4,img_sun4c,img_sun4m,img_sun4d,img_sun4e" +See +.B \-B +above. +.TP +.BI \-sparc\-label " label" +Set the Sun disk label name for the Sun disk label that is created with +.BR \-sparc-boot . +.TP +.B \-split\-output +Split the output image into several files of approximately 1 GB each. +This helps to create DVD-sized ISO9660 images on operating systems without +large file support. +.B wodim +will concatenate more than one file into a single track if writing to a DVD. +To make +.B \-split\-output +work, +.BI \-o " filename" +must be specified. The resulting output images will be named: +.IR filename_00 ", " filename_01 ", " filename_02 .... +.TP +.BI \-stream\-media\-size " #" +Select streaming operation and set the media size to # sectors. +This allows you to pipe the output of the +.BR tar (1) +program into +.B genisoimage +and to create an ISO9660 filesystem without the need of an intermediate +tar archive file. +If this option has been specified, +.B genisoimage +reads from +.I stdin +and creates a file with the name +.IR STREAM.IMG . +The maximum size of the file (with padding) is 200 sectors less than the +specified media size. If +.B \-no\-pad +has been specified, the file size is 50 sectors less than the specified media size. +If the file is smaller, +.B genisoimage +will write padding. This may take awhile. +.IP +The option +.B \-stream\-media\-size +creates simple ISO9660 filesystems only and may not used together with multisession +or hybrid filesystem options. +.TP +.BI \-stream\-file\-name " name" +Reserved for future use. +.TP +.BI \-sunx86\-boot " UFS_img,,,AUX1_img" +Specifies a comma-separated list of filesystem images that are needed to make +a bootable CD for Solaris x86 systems. +.IP +Note that partition 1 is used for the ISO9660 image and that partition 2 is +the whole disk, so partition 1 and 2 may not be used by external partition data. +The first image file is mapped to partition 0. +There may be empty fields in the comma-separated list, +and list entries for partition 1 and 2 must be empty. +The maximum number of supported partitions is 8 (although the Solaris x86 +partition table could support up to 16 partitions), so it is impossible +to specify more than 6 partition images. +This option is required to make a bootable CD for Solaris x86 systems. +.IP +If +.B \-sunx86\-boot +has been specified, the first sector of the resulting image will +contain a PC fdisk label with a Solaris type 0x82 fdisk partition that +starts at offset 512 and spans the whole CD. +In addition, for the Solaris type 0x82 fdisk partition, there is a +SVr4 disk label at offset 1024 in the first sector of the CD. +This disk label specifies slice 0 for the first (usually UFS type) +filesystem image that is used to boot the PC and slice 1 for +the ISO9660 image. +Slice 2 spans the whole CD slice 3 .\|.\|. slice 7 may be used for additional +filesystem images that have been specified with this option. +.IP +A Solaris x86 boot CD uses a 1024 byte sized primary boot that uses the +.B El-Torito no-emulation +boot mode and a secondary generic boot that is in CD sectors 1\|.\|.15. +For this reason, both +.BI "-b " bootimage " \-no\-emul\-boot" +and +.BI \-G " genboot" +must be specified. +.TP +.BI \-sunx86\-label " label" +Set the SVr4 disk label name for the SVr4 disk label that is created with +.BR \-sunx86-boot . +.TP +.BI \-sysid " ID" +Specifies the system ID.

UDF +support is currently in alpha status and for this reason, it is not +possible to create UDF-only images. UDF data structures are currently +coupled to the Joliet structures, so there are many pitfalls with the +current implementation.

Unicode or ISO-10646 +define character codings that need at least 21 bits to represent all +known languages. They may be represented with +.IR UTF-32 ", " UTF-16 " or " UTF-8 +coding. UTF-32 uses a plain 32-bit coding but seems to be uncommon. +UTF-16 is used by Microsoft with Win32 with the disadvantage that +16-bit characters are not compliant with the POSIX filesystem +interface. +.PP +Modern Unix operating systems may use UTF-8 coding for filenames. +Each 32-bit character is represented by one or more 8-bit characters. +If a character is coded in +.I ISO-8859-1 +(used in Central Europe and North America) is maps 1:1 to a +UTF-32 or UTF-16 coded Unicode character. +If a character is coded in +.I 7-Bit ASCII +(used in USA and other countries with limited character set) +is maps 1:1 to a UTF-32, UTF-16 or UTF-8 coded Unicode character. +Character codes that cannot be represented as a single byte in UTF-8 +(if the value is > 0x7F) use escape sequences that map to more than +one 8-bit character. +.PP +If all operating systems used UTF-8, +.B genisoimage +would not need to recode characters in filenames. +Unfortunately, Apple uses completely nonstandard codings and Microsoft +uses a Unicode coding that is not compatible with the POSIX filename +interface. +.PP +For all non-UTF-8-coded operating systems, the actual character +that each byte represents depends on the +.I character set +or +.I codepage +(the name used by Microsoft) +used by the local operating system \(em the characters in a character +set will reflect the region or natural language set by the user. +.PP +Usually character codes 0x00-0x1f are control characters, codes 0x20-0x7f +are the 7-bit ASCII characters and (on PCs and Macs) 0x80-0xff are used +for other characters. +.PP +As there are a lot more than 256 characters/symbols in use, only a small +subset are represented in a character set. Therefore the same character code +may represent a different character in different character sets. So a filename +generated, say in central Europe, may not display the same character +when viewed on a machine in, say eastern Europe. +.PP +To make matters more complicated, different operating systems use +different character sets for the region or language. For example, the +character code for `\('e' (small e with acute accent) +may be character code 0x82 on a PC, +code 0x8e on a Macintosh, code 0xe9 on a Unix system in western Europe, +and code 0x000e9 in Unicode. +.PP +As long as not all operating systems and applications use the same +character set as the basis for filenames, it may be +necessary to specify which character set your filenames use in and which +character set the filenames should appear on the CD. +.PP +There are four options to specify the character sets you want to use: +.TP +.B \-input\-charset +Defines the local character set you are using on your host machine. +Any character set conversions that take place will use this character +set as the starting point. The default input character sets are +.I cp437 +on MS-DOS-based systems and +.I iso8859-1 +on all other systems. If +.B \-J +is given, the Unicode equivalents of the input character set +will be used in the Joliet directory. +.B \-jcharset +is the same as +.BR "\-input\-charset \-J" . +.TP +.B \-output\-charset +Defines the character set that will be used with for the Rock Ridge names +on the CD.

Only useful when used with +.BR \-mac\-name . +See the +.B HFS MACINTOSH FILENAMES +for more information. Defaults to +.I cp10000 +(Mac Roman). +.TP +.B \-output\-hfs\-charset +Defines the HFS character set used to create HFS filenames from the input +character set in use. In most cases this will be from the character set +given with +.BR \-input\-charset . +Defaults to the input HFS character set. +.PP +There are a number of character sets built in to +.BR genisoimage . +To get a listing, use +.BR "\-input\-charset help" . +This list doesn't include the charset derived from the current locale, +if +.B genisoimage +is built with +.I iconv +support. +.PP +Additional character sets can be read from file for any of the character +set options by giving a filename as the argument to the options. The given +file will only be read if its name does not match one of the built-in +character sets. +.PP +The format of the character set files is the same as the mapping files +available from +.IR http://www.unicode.org/Public/MAPPINGS . +This format is: +.IP +Column #1 is the input byte code (in hex as 0xXX) +.br +Column #2 is the Unicode (in hex as 0xXXXX) +.br +The rest of the line is ignored. +.PP +Any blank line, line without two (or more) columns in the above format +or comments lines (starting with the # character) are ignored without any +warnings. Any missing input code is mapped to Unicode character 0x0000. +.PP +Note that, while UTF-8 is supported, other Unicode encodings such as +UCS-2/UTF-16 and UCS-4/UTF-32 are not, as POSIX operating systems +cannot handle them natively. +.PP +A 1:1 character set mapping can be defined by using the keyword +.I default +as the argument to any of the character set options. This is the behaviour +of old versions of +.BR mkisofs . +.PP +The ISO9660 filenames generated from the input filenames are not converted +from the input character set. The ISO9660 character set is a very limited +subset of the ASCII characters, so any conversion would be pointless. +.PP +Any character that +.B genisoimage +cannot convert will be replaced with a `_' character. +.\" ---------------------------------------- +.SH "HFS CREATOR/TYPE" +A Macintosh file has two properties associated with it which define +which application created the file, the +.I CREATOR +and what data the file contains, the +.IR TYPE . +Both are (exactly) 4 letter strings.

If +.B \-map +is given first, a filename extension match is attempted +before a magic number match. However, if +.B \-magic +is given first, a magic number match is attempted before a +filename extension match. +.PP +If a mapping or magic file is not used, or no match is found, the default +CREATOR and TYPE for all regular files can be set by using entries in the +.I .genisoimagerc +file or using +.B \-hfs\-creator +and/or +.BR \-hfs\-type , +otherwise the default CREATOR and TYPE are +.IR Unix " and " TEXT . +.PP +The format of the +.I mapping +file is the same +.I afpfile +format as used by +.BR aufs . +This file has five columns for the +.IR extension , +.IR "file translation" , +.IR CREATOR , +.IR TYPE " and" +.IR Comment . +Lines starting with the `#' character are +comment lines and are ignored.

Most of the HFS features work +fine, but some are not fully tested. These are marked as +.I Alpha +above. +.PP +Although HFS filenames appear to support uppercase and lowercase letters, +the filesystem is case-insensitive, i.e., the filenames +.IR aBc " and "AbC +are the same. If a file is found in a directory with the same HFS name, +.B genisoimage +will attempt to make a unique name by adding `_' characters +to one of the filenames. +.PP +HFS file/directory names that share the first 31 characters have +`_N' (a decimal number) substituted for the last few characters +to generate unique names. +.PP +Care must be taken when "grafting" Apple/Unix files or directories (see +above for the method and syntax involved). It is not possible to use a +new name for an Apple/Unix encoded file/directory. e.g. If a Apple/Unix +encoded file called +.I oldname +is to added to the CD, you cannot use the command line: +.IP +genisoimage \-o output.raw \-hfs \-graft\-points newname=oldname cd_dir +.PP +.B genisoimage +will be unable to decode +.IR oldname . +However, you can graft +Apple/Unix encoded files or directories as long as you do not attempt to +give them new names as above. +.PP +When creating an HFS volume with the multisession options, +.B \-M +and +.BR \-C , +only files in the last session will be in the HFS volume. i.e. +.B genisoimage +cannot +.I add +existing files from previous sessions to the HFS volume. +.PP +However, if each session is created with +.BR \-part , +each session will appear as +separate volumes when mounted on a Mac. In this case, it is worth using +.BR \-V " or " \-hfs\-volid +to give each session a unique volume name, +otherwise each "volume" will appear on the Desktop with the same name. +.PP +Symbolic links (as with all other non-regular files) are not added to +the HFS directory. +.PP +Hybrid volumes may be larger than pure ISO9660 volumes +containing the same data. In some cases (e.g. DVD sized volumes) the +difference can be significant. As an HFS volume gets bigger, so does the +allocation block size (the smallest amount of space a file can occupy). +For a 650MB CD, the allocation block is 10kB, for a 4.7GB DVD it will be +about 70kB. +.PP +The maximum number of files in an HFS volume is about 65500 \(em although +the real limit will be somewhat less than this. +.PP +The resulting hybrid volume can be accessed on a Unix machine by using +the hfsutils routines. However, no changes can be made to the volume as it +is set as +.B locked. +The option +.B \-hfs\-unlock +will create an output image that is unlocked \(em however no changes should be +made to the contents of the volume (unless you really know what you are +doing) as it's not a "real" HFS volume. +.PP +.B \-mac\-name +will not currently work with +.B \-T +\(em the Unix name will be used in the +.I TRANS.TBL +file, not the Macintosh name. +.PP +Although +.B genisoimage +does not alter the contents of a file, if a binary file has its TYPE +set as +.IR TEXT ", it " may +be read incorrectly on a Macintosh. Therefore a better choice for the +default TYPE may be +.IR ???? . +.PP +.B \-mac\-boot\-file +may not work at all... +.PP +May not work with PC Exchange v2.2 or higher files (available with MacOS 8.1). +DOS media containing PC Exchange files should be mounted as type +.B msdos +(not +.BR vfat ) +when using Linux. +.PP +The SFM format is only partially supported \(em see +.B HFS MACINTOSH FILE FORMATS +section above. +.PP +It is not possible to use +.BR \-sparc\-boot " or " \-generic\-boot " with" +.BR \-boot\-hfs\-file " or " \-prep\-boot . +.PP +.B genisoimage +should be able to create HFS hybrid images over 4Gb, although this has not +been fully tested. +.\" ---------------------------------------- +.SH "SEE ALSO" +.BR genisoimagerc (5), +.BR wodim (1), +.BR mkzftree (8), +.BR magic (5). +.\" ---------------------------------------- +.SH AUTHORS +.B genisoimage +is derived from +.B mkisofs +from the +.B cdrtools 2.01.01a08 +package from May 2006 (with few updates extracted from cdrtools 2.01.01a24 from +March 2007) from .IR http://cdrecord.berlios.de/ , +but is now part of the +.B cdrkit +suite, maintained by Joerg Jaspert, Eduard Bloch, Steve McIntyre, Peter +Samuelson, Christian Fromme, Ben Hutchings, and other contributors. +The maintainers can be contacted at +.IR debburn-devel@lists.alioth.debian.org , +or see the +.B cdrkit +project web site at +.IR http://www.cdrkit.org/ . +.PP +Eric Youngdale wrote the first versions (1993\(en1998) of +.BR mkisofs . +J\(:org Schilling wrote the SCSI transport library and its +interface, and has maintained +.B mkisofs +since 1999.
