Is there a command to install a dmg

Question

I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format.

file says my dmg file is a VAX COFF executable.

Answer 1

First, mount the dmg image : hdiutil attach <image>.dmg

The image will be mounted to /Volumes/<image>. Mine contained a package which i installed with: sudo installer -package /Volumes/<image>/<image>.pkg -target /

Finally unmount the image: hdiutil detach /Volumes/<image>.

Answer 2

You should be able to mount the .dmg using:

hdiutil attach /path/to/file.dmg

And then copy its contents (which appears in /Volumes) where ever you like.

Answer 3

I had to mount and copy the .app to /Applications folder. For Etcher.app:

First as @trojanfoe said :

sudo hdiutil attach /Users/janatac/Etcher-1.2.1.dmg

Then

sudo cp -R /Volumes/Etcher\ 1.2.1/Etcher.app /Applications

You then have your application in /Applications folder

Don't forget to unmount the volume :

sudo hdiutil unmount /Volumes/Etcher\ 1.2.1/

Got it working after reading instructions from a blog post.

If you want to script the install it requires a few more steps since the name of the .dmg file, the name of the Volume created, the name of the application, and the name of the device that needs to be detached can all be different. Plus they can have spaces in them.

Also a .dmg can have an .app file or a .pkg file in it and these require different behavior.

Here's a bash function to install a dmg from a remote URL:

# usage: installdmg https://example.com/path/to/pkg.dmg
function installdmg {
    set -x
    tempd=$(mktemp -d)
    curl $1 > $tempd/pkg.dmg
    listing=$(sudo hdiutil attach $tempd/pkg.dmg | grep Volumes)
    volume=$(echo "$listing" | cut -f 3)
    if [ -e "$volume"/*.app ]; then
      sudo cp -rf "$volume"/*.app /Applications
    elif [ -e "$volume"/*.pkg ]; then
      package=$(ls -1 "$volume" | grep .pkg | head -1)
      sudo installer -pkg "$volume"/"$package" -target /
    fi
    sudo hdiutil detach "$(echo "$listing" | cut -f 1)"
    rm -rf $tempd
    set +x
}

Note if your .dmg has an .app file that runs to install the program, then you will need to do something different again.

Answer 5

You could try the command open disk://host.tld/image.dmg.

Answer 6

After you've downloaded the.dmg file. By pressing the right button, the file must be mounted and opened with the same picture.DiskImageMounter(Default).

.

The. app file will then be shown. When the. app file appears, open the terminal and navigate to the write directory where the file is located. and type open -a/ExistingFileName.app in the command prompt, then press enter. This is how I use the macOS terminal to launch the.dmg file.
