How to start Genymotion device with shell command?

I need to start genymotion via shell command, does anyone know if it is possible to do this?

Genymotion proposes a shell: the Genymotion Shell. It is not currently possible to start a VM with it.

But you can however launch a Genymotion VM thanks to this command:

player --vm-name <VM id | VM name>

This command launches the Genymotion's player that gives you access to all the Genymotion enhancements widgets (GPS, battery, rotation, ...), the screen scaling, rendering, ... Like the standard GUI launch.

If you want to use a Genymotion VM without the enhancements, you can launch it via the VirtualBox command line like this:

VBoxManage startvm gui <VM id | VM name>

The VM id can be found thanks to this command line:

VBoxManage list vms

It displays a list of your VirtualBox machines on this format: name {id}.

UPDATE

Since Genymotion 2.5.0 you can manage all your Genymotion devices thanks to a command line tool. With this tool you can create, start, stop, delete, push files, flash the device, ... Here is a simple example to create a device and start it:

gmtool admin create "Google Nexus 5 - 4.4.4 - API 19 - 1080x1920" myNexus
gmtool admin start myNexus

This feature is available for paid licenses.

As of Genymotion 2.6.0 (Dec 2015), it appears they have moved the player executable to be player.app.

On OSX you can launch a desired VM like this:

# First, get a list of the VM's you have installed
VBoxManage list vms
# Returns something like "5.0.0 - API 21 - 768x1280" {091d022d-6a7b-4475-845f-7a6e06024fb6}

Copy the VM ID, e.g. 091d022d-6a7b-4475-845f-7a6e06024fb6, and then use it again like this:

# Launch a specific VM
open -a /Applications/Genymotion.app/Contents/MacOS/player.app --args --vm-name '091d022d-6a7b-4475-845f-7a6e06024fb6'

For windows.

Retrieve the list of available virtual devices by running:

<Genymotion installer path>\genyshell -c "devices list"

Start one of the virtual devices by running:

<Genymotion installer path>\player --vm-name "<virtual device name>"

UPD 8 may 2019: I'm create simple wrapper for genymotion cli on bash. Link to github here.
