This is an easy way to mount OS X installer packages (.dmg files) from the command line tool.
First of all, you must have your .DMG file, or you can download it still using the shell.
To download with command line use the curl command:
MacMini>curl http://web.address.pointing.to/the/file/to/download.dmg > myFile.dmg
Then to mount the image use the following command:
MacMini> hdid myFile.dmg
That’s all!
