Selenium-GIT hub ssh.exe Test

Hi,

I was following the Selenium video 44, under module 3 where we download the GIT, generate ssh keys and finally try to test the connection using command "ssh.exe -T git@github.com"
from command i get the message 'ssh.exe' is not recognized as an internal or external command.

i am under folder "C:\Program Files\GIT\bin". All the previous commands discussed in the video are successful. Can you please help me out. Thanks!
