If you double click a disk image in the Finder, it is mounted automatically.

Sometimes when a disk image is mounted, it will prompt you to agree to a license first.

In that case, the text that would normally appear in a GUI dialog box instead appears in the Terminal window.

Once you scroll to the bottom of the agreement, you can type in Y to continue or N to stop.

The Firefox disk image is one example of a package that displays a license before mounting.

Install the application Use the cp command to copy the application to Applications: sudo cp -R VolumesChicken of the VNCChicken of the VNC.app Applications The -R switch means to copy recursively, in other words, copy everything from that location including all subdirectories and files below.

It is important to leave off the trailing from the Chicken of the VNC.app directory, or the command will not copy the directory itself, just the contents.

After entering your password, the application will be installed and ready to use.

Most applications can simply be copied to the Applications directory.

To install a.pkg, use this command: sudo installer -package pathtopackage -target VolumesMacintosh HD Unmount the disk image To tidy up, return to your home directory and unmount the disk image: cd hdiutil unmount VolumesChicken of the VNC You should see this message after the unmount: VolumesChicken of the VNC unmounted successfully.

Installing applications from a.dmg package at the command line is not something you need to do every day.

But it is a nice tool to have if you want to install an application on a remote server or script the installation of a package to a group of desktop Macs.
