Put output into an array
I'm trying to take the output of an environment that has multiple strings

ex.
Code:
# echo $SSH_CLIENT
192.168.1.1 57039 22

I need that IP... so I can set it to another environment.

Thank you

Thank you Franklin52.

Is there any way I could have a break down on why that works so I may better understand it?
