# BibleSD Duplication

The simplest (but longest) method to duplicate this BibleSD is to simply select the files through the graphical interface, copy them onto your computer, and then onto new media. This approach works on all operating systems.

A faster method to duplicate this BibleSD is to copy it as one image file to your computer, and then copy that one image file onto a new microSD card or other flash media. On Mac or Linux this can be accomplished without additional software, using only system commands. On Windows or other operation systems, this requires software like [Etcher](https://etcher.balena.io/).

##### Find the device name and mount point

Open a new **Terminal** window (CTRL+ALT+T on Ubuntu-based Linux distributions).

Type one of the following commands and press Enter:

<table border="1" id="bkmrk-mac-linux-diskutil-l" style="border-collapse: collapse; width: 100%; height: 59.5938px;"><colgroup><col style="width: 50%;"></col><col style="width: 50%;"></col></colgroup><tbody><tr style="height: 29.7969px;"><td style="height: 29.7969px;">**Mac**</td><td style="height: 29.7969px;">**Linux**</td></tr><tr style="height: 29.7969px;"><td style="height: 29.7969px;">`diskutil list`</td><td style="height: 29.7969px;">`df -h`</td></tr></tbody></table>

This command displays a table of mounted disks and media.

For Mac, we will need the **IDENTIFIER** name (example: `disk1`). For Linux, we will need the **Filesystem** name (example: `/dev/mmcblk0`) and the location **Mounted On** (example: `/media/giw/DCA2-3AA0`).

To unmount the

Wait to connect the microSD card or other flash media that will receive the image file (or disconnect if already connected).

Type this command into the **Terminal** and press the **Enter** key:

```bash
ls /dev
```

This command will display a list of devices connected to your computer.

Connect the microSD card or flash media to your computer and then repeat the same command. You can type it again or press the UP arrow key to cycle through previous commands and then press the **Enter** key.

Compare the difference between the two lists of devices to determine which device was connected. On Linux, the name of the microSD card or flash media will probably be `mmcblk0`, but may be different in some cases.
