I usually create a DMG package to redistribute to MacOS, but I would like to add compression as Apple specifies. Did anyone have a chance to try a tool that supports compression during DMG packing? Similar questions without compression: How can I generate a DMG file from a folder in Linux? How to create dmg file in Centos through command line. May 16, 2018 On Ubuntu, you’d do: sudo apt-get install dmg2img. Using dmg2img isn’t very difficult. Type “dmg2img” into the command line followed by the name of the DMG file you want to decompress. The Mac OS X version of Firefox is a good example of a compressed DMG file. Hfs-test$ dmg2img 'Firefox 33.1.1.dmg' dmg2img. Linux, macOS, Windows, ARM, and containers. Hosted runners for every major OS make it easy to build and test all your projects. Run directly on a VM or inside a container. Use your own VMs, in the cloud or on-prem, with self-hosted runners.

A disk image is a computer file containing the complete contents and structure of a data storage device.

The term has been generalized to cover any such file, whether taken from an actual physical storage device or not.

A common use of disk images is for remote distribution of software such as Linux distributions: installation CD/DVDs can be recorded as disk image files, transferred over the Internet, and the contents of the original disk(s) duplicated exactly by end users with their own CD/DVD drives. They are commonly used to distribute Live CDs.

Another common use is to provide virtual disk drive space to be used by SystemVirtualization. This can prevent the CD from getting burned or damaged. It can also reduce bulk when one wishes to carry the contents of the CD along with oneself: one can store disk images to a relatively lightweight and bootable storage device which has a higher storage capacity than that of a CD (i.e. a USB keydrive).

.iso

An ISO image (.iso) is an informal term for a disk image of an ISO 9660 FileSystem. More loosely, it refers to any optical disk image.

As is typical for disk images, in addition to the data files that are contained in the ISO image, it also contains all the filesystem metadata (Boot code, structures, and attributes). All of this information is contained in a single file. These properties make it an attractive alternative to physical data storage device for the distribution of software which requires this additional information as it is simple to retrieve over the Internet. It is commonly used fir the distribution of Linux and LiveCDs.

You can create, open and mount ISO images using CD and DVD applications. See ManipulatingISOs for info on manipulating ISO disk images.

ISO images have the MIME type application/x-iso-image

.bin / .raw / .img

.bin, .raw, or .img files are images extracted in pure RAW format.

For a CD, that is 2352 bytes sectors, the full CD sector content: user data, sector header, error correction codes (ECC) and error detection codes (EDC). Once again, each sector is converted to digital data in the .BIN file, but more stuff is copied and the resulting file will be bigger. The .BIN file should be 251,000 x 2352 = 590,352,000 bytes big. This process will copy ANYTHING on the disc, so it is useful for exotic discs (multiple tracks, mixed track type Audio+Data or Data+Audio) and for non-PC CDs (PSX, VCD, MAC).

This extension is also commonly used for hard disk images.

.cue

Sometimes .bin images come with a cue file, describing the layout of CD tracks.

You can burn a CD using the information from the cue file with cdrdao: cdrdao write --speed 4 --device 0,1,0 example.cue

.dmg

A DMG file is an Apple Disk Image, a popular format on Mac OS X. It is widely used for software distribution means, and is actually the raw image of a HFS filesystem, that's why in Mac OS X it is mounted as a drive.

DMG disk images have the MIME type application/x-apple-diskimage

To create a .dmg image from a HFS formatted CD or hard drive partition: dd if='your input file' of=image.dmg

To mount a .dmg disk image to a directory, you need to install the hfsplus package, then mount it with mount -o loop -t hfs image.dmg /mnt/somewhere

.nrg

.nrg is a Nero disk image.

You can mount it to a directory using: mount -o loop,offset=307200 imagename.nrg /mount-point

This guide covers the verbatim copying of a DMG image to a USB thumb drive using only Linux (no need to find a Mac). If the DMG was intended to be bootable then the resulting USB will be bootable.

Convert to ISO

Linux doesn’t much care for DMG files. Sure, it’ll play nice with them. But we don’t just want to play nice. We want to copy a DMG image to a USB drive and keep it as verbatim as computationally possible. In order to do this, we’re first going to convert the image to a format that’s a little more universal: ISO.

We’re going to use dmg2img to convert the DMG to an ISO image. If you already have dmg2img, great. If not, install it using your distribution’s native package management system.

On Ubuntu, you’d do it like this:

Once you have dmg2img installed, begin converting the DMG file:

After a few minutes, you should have a second file called image.img. This file can be used like an ISO. All we have to do is change the extension. Use mv to do this:

Make sure you specified “image.img” and not “image.dmg”! Working with three different file extensions can get kind of confusing.

Ok, so we should now have a file called “image.iso” which is just “image.img” with a different extension.

Now we want to write “image.iso” to our USB drive. I used “lsblk” to figure out how the system was identifying my drive. The lsblk command lists all disks connected to the system. It’s usually pretty easy to figure out which disk is which based on their size. Just be sure you’re sure. This process is going to overwrite the target disk with the contents of our DMG image file. Any preexisting files on the target disk will be lost. As usual, make sure you have a proper backup.

Make sure the target drive isn’t mounted. Unmount the drive with your distribution’s GUI.

Or you could just unmount it from the terminal:

Most systems seem to mount external drives in /media. Sometimes the drive might be mounted in /mnt or elsewhere.

Write the ISO image to the USB drive like this:

Replace “X” with the appropriate letter. For example “/dev/sdb”. Be sure to use the drive directly and not a partition within the drive. For example, don’t use “/dev/sdb1”.

This will probably take a little while to complete. I’m using a Kingston DataTraveler DTSE9 and it took about 24 minutes 30 seconds to write 4.9GB.

Your new USB stick should now be bootable, assuming that was the intended purpose of the DMG.
