Can I ask you how to convert an .dmg file into an .iso file, so that I would be able to burn it on the cd?

And ideas?

[/quote] 20. Convert .dmg files to .iso [Computer Tips]

Use this terminal command to convert a .dmg to .iso:

Code: Select all

hdiutil convert /path/to/file.dmg -format UDTO -o /path/to/file.iso

http://convertiso.fehsiso.com/convertdmgiso/
http://convertiso.fehsiso.com/toconvertdmgtoiso/

Code: Select all

hdiutil convert /dev/disk1s1s2 -format UDTO -o ~/Desktop/CD Name hdiutil burn ~/Desktop/CDName.dmg -noverifyburn -noeject creating data dvds mkisofs -V Disk Label -J -r -o myimage.iso data_dir ...

btw simple google search featuring the following words "dmg to iso linux" would have solved your problem within some seconds ...

Yes I tried that before and it said, that hdiutil command not found. When I tried to emerge it it says:

I found this perl script mirrored... somewhere... using Google. Credits go to Jeff Mahoney (the script writer, I assume)

ok man good 4 ya

reading is important now heres your solution
btw i remembered it because during my ipod shuffle isntall i read something about youre question content

this is how it should work we use a little pl script from gnupod , be sure to have pearl installed

Code: Select all

# Grab a working copy of dmg2iso.pl
wget http://blinkenlights.ch/gnupod/dmg2iso.pl
# Convert the dmg into iso
perl dmg2iso.pl yourfile.dmg yournewfile.iso

hope it works and makes you happy

because its weekend and everyone should be happy haeh?
please post if worked

btw sry because of hdiutil is only avaible on mac

forgot about this but with those 2 commands above it should work as well who someone else had same idea maybe even same script

Didn't work:

Moved from Installing Gentoo

kasperhans · Post by **kasperhans** » Fri Nov 25, 2005 8:39 pm

you need perl moudle Compress::Zlib ...

btw what do you actual plan to do for dmg to iso?
you plan to illegaly rip a macos dvd ???

eleanor · Post by **eleanor** » Sat Nov 26, 2005 10:35 am

dmg2iso v0.2a by vu1tur (vu1tur@gmx.de)

reading property list...found 4 partitions
decompressing:
partition 0
partition 1

Conversion failed. File may be corrupted.

Any ideas? The only thing left for me is to download an iso, right?

linuxtuxhellsinki · Post by **linuxtuxhellsinki** » Sat Nov 26, 2005 1:32 pm

My conversion went fine but it isn't show like .iso, so how-to make it bootable

Code: Select all

mandrake ~ # file OS7.5.3.iso
OS7.5.3.iso: data

This is how it supposed to look like.

Code: Select all

mandrake ~ # file dsl-1.0.iso
dsl-1.0.iso: ISO 9660 CD-ROM filesystem data 'KNOPPIX                        ' (bootable)

Is there some way to mount it via the loop device & add the bootable option in it ? I remember that there was written that U loose the bootable option when making the conversion to .iso.
