genisoimage command examples

genisoimage – create ISO9660/Joliet/HFS filesystem with optional Rock Ridge attributes

To create a vanilla ISO9660 filesystem image in the file cd.iso, where the directory cd_dir will become the root directory of the CD, call:

% genisoimage -o cd.iso cd_dir

 

To create a CD with Rock Ridge extensions of the source directory cd_dir:

% genisoimage -o cd.iso -R cd_dir

 

To create a CD with Rock Ridge extensions of the source directory cd_dir where all files have at least read permission and all files are owned by root, call:

% genisoimage -o cd.iso -r cd_dir

 

To write a tar archive directly to a CD that will later contain a simple ISO9660 filesystem with the tar archive call:

% tar cf - . | genisoimage -stream-media-size 333000 | \
wodim dev=b,t,l -dao tsize=333000s -

 

To create a HFS hybrid CD with the Joliet and Rock Ridge extensions of the source directory cd_dir:

% genisoimage -o cd.iso -R -J -hfs cd_dir

 

To create a HFS hybrid CD from the source directory cd_dir that contains Netatalk Apple/Unix files:

% genisoimage -o cd.iso --netatalk cd_dir

To create a HFS hybrid CD from the source directory cd_dir, giving all files CREATOR and TYPES based on just their filename extensions listed in the file “mapping”.:

% genisoimage -o cd.iso -map mapping cd_dir

To create a CD with the Apple Extensions to ISO9660, from the source directories cd_dir and another_dir. Files in all the known Apple/Unix format are decoded and any other files are given CREATOR and TYPE based on their magic number given in the file magic:

% genisoimage -o cd.iso -apple -magic magic -probe \ 
cd_dir another_dir

The following example puts different files on the CD that all have the name README, but have different contents when seen as a ISO9660/Rock Ridge, Joliet or HFS CD.

Current directory contains:

% ls -F

README.hfs README.joliet README.Unix cd_dir/

The following command puts the contents of the directory cd_dir on the CD along with the three README files — but only one will be seen from each of the three filesystems:

% genisoimage -o cd.iso -hfs -J -r -graft-points \
-hide README.hfs -hide README.joliet \
-hide-joliet README.hfs -hide-joliet README.Unix \
-hide-hfs README.joliet -hide-hfs README.Unix \
README=README.hfs README=README.joliet \
README=README.Unix cd_dir

i.e. the file README.hfs will be seen as README on the HFS CD and the other two README files will be hidden. Similarly for the Joliet and ISO9660/Rock Ridge CD.
