Launching an EC2 Instance
As per my Linux system, I could see all the list of folders that are in my system.
I type ls in the terminal and press Enter.
Since my AWSKey2.pem (Key Pair) is in Desktop, I type cd Desktop and press Enter.
To list all the files in my desktop, I type ls and press Enter.
To launch the EC2 instance, I type ssh ec2-user@public id address -I AWSKey2.pem
