[Theramya10]

Before running this command -> ssh-copy-id -f "-o IdentityFile " ubuntu@

Follow these steps to add your SSH .pem file and avoid manually entering the key each time you connect to your EC2 instance.

1. Add the SSH key to the SSH agent

sudo ssh-add ~/Downloads/id_rsa.pem

2. Move the SSH key to the .ssh directory

mv ~/Downloads/id_rsa.pem ~/.ssh/id_rsa.pem

3. Set correct permissions for the private key (restrict access)

chmod 400 ~/.ssh/id_rsa.pem

4. Add the key to the SSH agent again (if necessary)

sudo ssh-add ~/.ssh/id_rsa.pem

ssh ec2-user@
