How to Burn .DMG Files to USB from Command Line on Ubuntu 18.04

==================================================================================

This tutorial will show you how to burn a `.dmg` file onto a USB stick using only terminal commands in Ubuntu 18.04.

Prerequisites:

------------

* You have `sudo` privileges and are logged into your system as the root user.

* The `geniso9661`, `xorriso`, and `usbmount` packages are installed on your system. If not, you can install them by running:

```bash

sudo apt update -y && sudo apt install geniso9661 xorriso usbmount -y

```

Step-by-Step Instructions:

------------------------

### Step 1: Mount the .dmg file

Firstly, we need to mount our `.dmg` image onto a temporary directory. We can do this using `hdiutil`. To find out which USB drive is mounted as `/dev/sdx`, use:

```bash

lsblk -o NAME,FSTYPE,UUID,LABEL | grep /dev/

```

Assuming that the output shows something like `/dev/ sda1 ext4 e9f3a2d-6b42-45c7-b0ef-daf4e5bc56ab ` , you can proceed with mounting it as follows:

```bash

sudo mkdir -p /mnt && hdiutil mount -o ro,uniso -nobanner /path/to/your/file.dmg ~/Downloads/

```

Replace `/dev/sda1` and `file_name.dmg` with the actual path to your USB drive.

### Step 2: Convert .digm file to ISO format

Next up is converting our `.dmg` image into an ISO that can be burnt onto a USB stick. We'll use `hdiutil` for this task:

```bash

sudo hdiutil convert -format UDF -o ~/Downloads/usbdrive.iso /dev/sda1

```

Again, replace `/dev/sda1` with the actual path to your mounted `.dmg` file.

### Step 3: Write ISO image onto USB stick

Now that we have our `.iso` file ready, it's time to write it onto a blank USB drive. We'll use `dd` for this task:

```bash

sudo dd bs=4M if=/path/to/usbdrive.iso | pv -o /dev/sdx && sync

```

Replace `/path/to/usbdrive.iso` with the actual path to your ISO file and make sure that you have plugged in a blank USB stick before running this command.

### Step 5: Eject the device

Finally, let's unmount our temporary directory:

```bash

sudo umount ~/Downloads && rm -rf /mnt/

```

That concludes how to burn an `.iso` file onto a USB drive using only terminal commands in Ubuntu 18.04.
