Sissejuhatus ja ülevaade [1]
Mkisofs (make iso files) on käsk, mida kasutatakse CD kuvandite tegemiseks ISO 9660 standardi järgi. An ISO 9660 file system is a standard CD-ROM file system that allows you to read the same CD-ROM whether you're on a PC, Mac, or other major computer platform.[3] mkisofs is effectively a pre-mastering program to generate an ISO9660/JOLIET/HFS hybrid filesystem. mkisofs is capable of generating the System Use Sharing Protocol records (SUSP) specified by the Rock Ridge Interchange Protocol. This is used to further describe the files in the iso9660 filesystem to a unix host, and provides information such as longer filenames, uid/gid, posix permissions, symbolic links, block and character devices.

Käsu formaat [2]
mkisofs [ options ] [ -o filename ] pathspec [pathspec ...] mkisofs [ options ] [ -o filename ] -find [find expression]
A mkisofs run needs one or more input directories or files and a name for the emerging filesystem image file. There are options for standards compliance, for filesystem attributes, and -most important here- for setting up boot entry points.
-o DISKPATH sets the result file name. E.g. "bootable.iso".
-R enables normal Unix filenames and attributes by Rock Ridge extension. -r does the same but also changes access permissions to make all files readable by everybody.
-J enables MS-Windows UCS-2 names via Joliet extension.
-iso-level NUMBER sets the ISO 9660 Level of Interchange. Level 1 allows only 8.3 filenames. Level 2 allows up to 30 characters in filenames. Level 3 allows data files larger than 4 GiB - 1.
-U violates ISO 9660 specs by allowing long case-sensitive filenames outside of said extensions. If you know that the reader can stand it, then this is a cheap way to get decent file names. But expect standard readers to become confused.
-V TEXT sets the ISO 9660 Volume ID. It can be up to 32 characters long and is often used by automounters as name of the mount directory for the filesystem.
-hide ISOPATH and -hide-joliet ISOPATH may be used to exclude a data file from the directory trees while still having its content in data blocks of the filesystem.
-c ISOPATH sets the filename for the El Torito Boot Catalog. The file is created automatically if boot images are announced. If option -c is missing, then the file will not show up in the directory trees of the ISO filesystem.
-b ISOPATH announces a data file as El Torito boot image for PC-BIOS.
-e ISOPATH announces a data file as El Torito boot image for EFI. This is not an option of original mkisofs, but is understood by some variants of genisoimage and by xorriso -as mkisofs.
-no-emul-boot and -hard-disk-boot choose emulation modes other than the default of floppy emulation. Especially -no-emul-boot is needed for boot images of ISOLINUX and GRUB2.
-boot-load-size NUMBER sets how many blocks of the boot image are to be loaded by the BIOS. A usual number with -no-emul-boot is 4.
-boot-info-table causes a Boot Info Table to be written into the boot image. Needed for boot images of ISOLINUX and GRUB2.
-eltorito-alt-boot ends the range of -b or -e. All further El Torito boot options will apply to the next boot image given by -b or -e.
-G DISKPATH copies the content of a data file into the System Area of the ISO filesystem. This is used to bring MBR or other boot blocks into the filesystem to enable booting from hard-disk-like devices or booting on exotic hardware.
-isohybrid-mbr DISKPATH copies a SYSLINUX/ISOLINUX MBR template into the System Area and makes it execute the El Torito boot image for BIOS. This is a speciality of xorriso -as mkisofs.
-isohybrid-gpt-basdat announces the boot image as GPT partition for booting via EFI and as MBR partition. This is a speciality of xorriso -as mkisofs.
-graft-points enables the interpretation of pathspecs which give a target path in the ISO filesystem together with the path of an input directory or file.
A program argument, which is not recognized as option (e.g. because it does not begin by a dash "-") and is not parameter of an option, is taken as path to an input directory or file. If it is a directory, then its content gets merged with the content of the root directory of the emerging ISO filesystem. If it is a file of other type, then it gets copied into the root directory.
If enabled, then pathspecs get recognized by an equal sign which separates target path from source path. E.g.
