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