DMG images are the way that a lot of MacOSX binary packages are distributed. They are somehow like virtual hard disk images or .iso images that you can just mount with a simple double click if you have access to the gui.
But how do you do that from the command line?
hdiutil attach image.dmg
and the image should now be mounted somewhere in /Volumes
The hdiutil is a tool used to manipulate such disk images. It can do a lot more then just mount the images. It can even burn them to an optical media, convert them to an iso and some other formats , even compress them using gzip or bzip2 .
I'm going to write some posts about doing stuff on MacOSX.
I'm a beginner mac user and I come from a Unix background. I use/administrate/patch/develop on Unix like machines ( mostly just Linux and FreeBSD ) on a daily basis.
Since MacOSX has Unix at it's roots using it shouldn't be hard for me to work with it...right...well I'll see how much it has changed.
Sometimes I find it difficult to do something on MacOSX mostly because I am used to how it is done in Unix and because I don't want or can't use the GUI tools.
The fact that most of the tutorials I find are also explaining how to do stuff in the GUI makes this an even bigger problem.
So I decided that when I actually find out how to do what I want to do I will write a post about it so I will not have to look for it again.
