.B \-hide
option.
.TP
.BI \-hide-joliet-list " file
A file containing a list of
.I globs
to be hidden as above.
.TP
.B \-hide-joliet-trans-tbl
Hide the 
.B TRANS.TBL
files from the Joliet tree.
These files usually don't make sense in the Joliet World as they list
the real name and the ISO9660 name which may both be different from the
Joliet name.
.TP
.B \-hide-rr-moved
Rename the directory 
.B RR_MOVED
to
.B .rr_moved
in the Rock Ridge tree.
It seems to be impossible to completely hide the
.B RR_MOVED
directory from the Rock Ridge tree.
This option only makes the visible tree better to understand for
people who don't know what this directory is for.
If you need to have no 
.B RR_MOVED
directory at all, you should use the 
.B \-D
option. Note that in case that the
.B \-D 
option has been specified, the resulting filesystem is not ISO9660
level-1 compliant and will not be readable on MS-DOS.
.TP
.B \-l
Allow full 30 character filenames.  Normally the ISO9660 filename will be in an
8.3 format which is compatible with MS-DOS, even though the ISO9660 standard
allows filenames of up to 30 characters.  If you use this option, the disc may
be difficult to use on a MS-DOS system, but this comes in handy on some other
systems (such as the Amiga).  Use with caution.
.TP
.B \-J
Generate Joliet directory records in addition to regular iso9660 file
names.  This is primarily useful when the discs are to be used on Windows-NT
or Windows-95 machines.   The Joliet filenames are specified in Unicode and
each path component can be up to 64 Unicode characters long.
.TP
.B \-L
Allow ISO9660 filenames to begin with a period.  Usually, a leading dot is
replaced with an underscore in order to maintain MS-DOS compatibility.
.TP
.BI \-log-file " log_file
Redirect all error, warning and informational messages to
.I log_file
instead of the standard error.
.TP
.BI \-m " glob
Exclude
.I glob
from being written to CDROM.
.I glob
is a shell wild-card-style pattern that must match part of the filename (not 
the path as with option
.BR -x ).
Technically
.I glob
is matched against the
.I d->d_name
part of the directory entry.
Multiple globs may be excluded (up to 1000).
Example:

mkisofs \-o rom \-m '*.o' \-m core \-m foobar

would exclude all files ending in ".o", called "core" or "foobar" to be
copied to CDROM. Note that if you had a directory called "foobar" it too (and
of course all its descendants) would be excluded.
.sp
NOTE: The \-m and \-x option description should both be updated, they are wrong.
Both now work identical and use filename globbing. A file is excluded if either
the last component matches or the whole path matches.
.TP
.BI \-exclude-list " file
A file containing a list of
.I globs
to be exclude as above.
.TP
.BI \-M " path 
or
.TP
.BI \-M " device
Specifies path to existing iso9660 image to be merged. The alternate form
takes a SCSI device specifier that uses the same syntax as the 
.B "dev=
parameter of 
.B cdrecord.
The output of 
.B mkisofs
will be a new session which should get written to the end of the
image specified in -M.  Typically this requires multi-session capability
for the recorder and cdrom drive that you are attempting to write this
image to.
This option may only be used in conjunction with the 
.B \-C
option.
.TP
.B \-N
Omit version numbers from ISO9660 file names.  This may violate the ISO9660
standard, but no one really uses the version numbers anyway.  Use with caution.
.TP
.B \-nobak
.TP
.B \-no-bak
Do not include backup files files on the iso9660 filesystem. 
If the 
.B \-no-bak
option is specified, files that contain the characters '~' or '#'
or end in '.bak' will not be included (these are typically backup files
for editors under unix).
.TP
.B \-no-rr
Do not use the Rock Ridge attributes from previous sessions.
This may help to avoid getting into trouble when
.B mkisofs
finds illegal Rock Ridge signatures on an old session.
.TP
.B \-no-split-symlink-components
Don't split the SL components, but begin a new Continuation Area (CE)
instead. This may waste some space, but the SunOS 4.1.4 cdrom driver
has a bug in reading split SL components (link_size = component_size 
instead of link_size += component_size).
.TP
.B \-no-split-symlink-fields
Don't split the SL fields, but begin a new Continuation Area (CE)
instead. This may waste some space, but the SunOS 4.1.4 and
Solaris 2.5.1 cdrom driver have a bug in reading split SL fields
(a `/' can be dropped).
.TP
.BI \-o " filename
is the name of the file to which the iso9660 filesystem image should be
written.  This can be a disk file, a tape drive, or it can correspond directly
to the device name of the optical disc writer.  If not specified, stdout is
used.  Note that the output can also be a block special device for a regular
disk drive, in which case the disk partition can be mounted and examined to
ensure that the premastering was done correctly.
.TP
.BI \-path-list " file
A file containing a list of
.I pathspec
directories and filenames to be added to the ISO9660 filesystem. This list
of pathspecs are processed after any that appear on the command line. If the
argument is
.IR - ,
then the list is read from the standard input. There must be at least one
.I pathspec
given on the command line as well.
.TP
.BI \-P " publisher_id
Specifies a text string that will be written into the volume header.
This should describe the publisher of the CDROM, usually with a
mailing address and phone number.  There is space on the disc for 128
characters of information.  This parameter can also be set in the file
.B \&.mkisofsrc
with PUBL=.
If specified in both places, the command line version is used.
.TP
.BI \-p " preparer_id
Specifies a text string that will be written into the volume header.
This should describe the preparer of the CDROM, usually with a mailing
address and phone number.  There is space on the disc for 128
characters of information.  This parameter can also be set in the file
.B \&.mkisofsrc
with PREP=.
If specified in both places, the command line version is used.
.TP
.B \-print-size
Print estimated filesystem size and exit. This option is needed for
Disk At Once mode and with some CD-R drives when piping directly into
.B cdrecord.
In this case it is needed to know the size of the filesystem before the
actual CD-creation is done.
The option \-print-size allows to get this size from a "dry-run" before
the CD is actually written.
.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
CD-Rom 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 file system, and set-id bits are not desirable for uid 0 or
gid 0.
.TP
.BI \-sysid " ID
Specifies the system ID.
This parameter can also be set in the file
.B \&.mkisofsrc
with SYSI=system_id.
If specified in both places, the command line version is used.
.TP
.B \-T
Generate a file TRANS.TBL in each directory on the CDROM, which can be used
on non-Rock Ridge capable systems to help establish the correct file names.
There is also information present in the file that indicates the major and
minor numbers for block and character devices, and each symlink has the name of
the link file given.
.TP
.BI \-table-name " TABLE_NAME
Alternative translation table file name (see above). Implies the
.B \-T
option.
If you are creating a multi-session image you must use the same name
as in the previous session.
.TP 
.B \-U
Allows "Untranslated" filenames, completely violating the iso9660 standards
described above. Forces on the -d, -l, -L and -N flags, and also allows more
than one '.' character in the filename, as well as mixed case filenames.
This is useful on HP-UX system, where the built-in CDFS filesystem does
not recognize ANY extensions. Use with extreme caution.
.TP
.BI \-V " volid 
Specifies the volume ID to be written into the master block.  This
parameter can also be set in the file
.B \&.mkisofsrc
with VOLI=id.
If specified in both places, the command line version is used.  Note that 
if you assign a volume ID, this is the name that will be used as the mount  
point used by the Solaris volume management system and the name that is
assigned to the disc on a Windows or Mac platform. 
.TP
.BI \-volset " ID
Specifies the volset ID.
This parameter can also be set in the file
.B \&.mkisofsrc
with VOLS=volset_id.
If specified in both places, the command line version is used.
.TP
.BI \-volset-size " #
Sets the volume set size to #. 
The volume set size is the number of CD's that are in a CD set.
The 
.B \-volset-size
option may be used to create CD's that are part of e.g. a Operation
System installation set of CD's.
The option 
.B \-volset-size
must be specified before
.B \-volset-seqno
on each command line.
.TP
.BI \-volset-seqno " #
Sets the volume set sequence number to #. 
The volume set sequence number is the index number of the current
CD in a CD set.
The option 
.B \-volset-size
must be specified before
.B \-volset-seqno
on each command line.
.TP
.B \-v
Verbose execution.
.TP
.BI \-x " path
Exclude
.I path
from being written to CDROM.
.I path
must be the complete pathname that results from concatenating the pathname
given as command line argument and the path relative to this directory.
Multiple paths may be excluded (up to 1000).
Example: 

mkisofs \-o cd \-x /local/dir1 \-x /local/dir2 /local
.sp
NOTE: The \-m and \-x option description should both be updated, they are wrong.
Both now work identical and use filename globbing. A file is excluded if either
the last component matches or the whole path matches.
.TP
.B \-z
Generate special SUSP records for transparently compressed files.  This is
only of use and interest for hosts that support transparent decompression.
This is an experimental feature, and no hosts yet support this, but there
are ALPHA patches for Linux that can make use of this feature.
.SH BOOT INFORMATION TABLE
When the
.B \-boot-info-table 
option is given,
.B mkisofs
will modify the boot file specified by the
.B \-b
option by inserting a 56-byte "boot information table" at offset 8 in
the file.  This modification is done in the source filesystem, so make
sure you use a copy if this file is not easily recreated!  This file
contains pointers which may not be easily or reliably obtained at boot
time.
.PP
The format of this table is as follows; all integers are in
section 7.3.1 ("little endian") format.
.sp
.RS +.2i
.ta 1.0i 2.5i 3.5i
.nf
Offset	Name	Size	Meaning
 8	bi_pvd	4 bytes	LBA of primary volume descriptor
12	bi_file	4 bytes	LBA of boot file
16	bi_length	4 bytes	Boot file length in bytes
20	bi_csum	4 bytes	32-bit checksum
24	bi_reserved	40 bytes	Reserved
.fi
.RE
.sp
The 32-bit checksum is the sum of all the 32-bit words in the boot
file starting at byte offset 64.  All linear block addresses (LBAs)
are given in CD sectors (normally 2048 bytes).
.SH CONFIGURATION
.B mkisofs
looks for the
.B \&.mkisofsrc
file,
first in the current working directory,
then in the user's home directory,
and then in the directory in which the
.B mkisofs
binary is stored.  This file is assumed to contain a series of lines
of the form 
.BI TAG= value,
and in this way you can specify certain options.
The case of the tag is not significant.
Some fields in the volume header
are not settable on the command line, but can be altered through this
facility.
Comments may be placed in this file,
using lines which start with a hash (#) character.
.TP
.B APPI
The application identifier
should describe the application that will be on the disc.
There is space on the disc for 128 characters of information.
May be overridden using the 
.B \-A 
command line option.
.TP
.B COPY
The copyright information,
often the name of a file on the disc containing the copyright notice.
There is space in the disc for 37 characters of information.
May be overridden using the 
.B \-copyright
command line option.
.TP
.B ABST
The abstract information,
often the name of a file on the disc containing an abstract.
There is space in the disc for 37 characters of information.
May be overridden using the 
.B \-abstract
command line option.
.TP
.B BIBL
The bibliographic information,
often the name of a file on the disc containing a bibliography.
There is space in the disc for 37 characters of information.
May be overridden using the 
.B \-bilio
command line option.
.TP
.B PREP
This should describe the preparer of the CDROM,
usually with a mailing address and phone number.
There is space on the disc for 128 characters of information.
May be overridden using the 
.B \-p 
command line option.
.TP
.B PUBL
This should describe the publisher of the CDROM,
usually with a mailing address and phone number.
There is space on the disc for 128 characters of information.
May be overridden using the 
.B \-P 
command line option.
.TP
.B SYSI
The System Identifier.
There is space on the disc for 32 characters of information.
May be overridden using the 
.B \-sysid
command line option.
.TP
.B VOLI
The Volume Identifier.
There is space on the disc for 32 characters of information.
May be overridden using the 
.B \-V 
command line option.
.TP
.B VOLS
The Volume Set Name.
There is space on the disc for 128 characters of information.
May be overridden using the 
.B \-volset
command line option.
.PP
.B mkisofs
can also be configured at compile time with defaults for many of these fields.
See the file defaults.h.
.SH AUTHOR
.B mkisofs
is not based on the standard mk*fs tools for unix, because we must generate
a complete  copy of an existing filesystem on a disk in the  iso9660
filesystem.  The name mkisofs is probably a bit of a misnomer, since it
not only creates the filesystem, but it also populates it as well.
.PP
.br
Eric Youngdale <[e-mail]> or <[e-mail]> wrote both the
Linux isofs9660 filesystem and the mkisofs utility.
The copyright for the mkisofs utility is held by
Yggdrasil Computing, Incorporated.
.SH NOTES
.B Mkisofs
may safely be installed suid root. This may be needed to allow 
.B mkisofs
to read the previous session when creating a multi session image.
.SH BUGS
.TP
\(bu
Any files that have hard links to files not in the tree being copied to the
iso9660 filesystem will have an incorrect file reference count.
.TP
\(bu
Does not check for SUSP record(s) in "." entry of the
root directory to verify the existence of Rock Ridge
enhancements.
.sp
This problem is present when reading old sessions while
adding data in multi-session mode.
.TP
\(bu
Does not properly read relocated directories in multi-session
mode when adding data.
.sp
Any relocated deep directory is lost if the new session does not
include the deep directory.
.sp
Repeat by: create first session with deep directory relocation
then add new session with a single dir that differs from the
old deep path.
.TP
\(bu
Does not re-use RR_MOVED when doing multi-session from TRANS.TBL
.TP
\(bu
Does not create whole_name entry for RR_MOVED in multi-session
mode.
.PP
There may be some other ones.  Please, report them to the author.
.SH FUTURE IMPROVEMENTS
Some sort of gui interface.
.SH AVAILABILITY
.B mkisofs
is available for anonymous ftp from tsx-11.mit.edu in
