rsa public key No such file or directory?

Question

I'm trying to follow along the Upskillcourses.com web dev online course. In lesson 11 I'm supposed to link up cloud9 to github.

I'm trying to get the SSH key. But it's not working:

ec2-user:~/environment $ cat ~/.ssh/id_rsa.pub
cat: /home/ec2-user/.ssh/id_rsa.pub: No such file or directory

I've copied it exactly like the instructor did. I'll be honest in that I don't really know what I'm doing or how to fix. Seems like no one else is having this problem. Thanks for any help

First, check for existing SSH Key using the following command:

ls -al ~/.ssh

Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following: id_xxxx.pub (ex: id_rsa.pub). If you don't have an existing public and private key pair, create one using this command:

ssh-keygen -t rsa -b 4096 -C "[email protected]"

This creates a new ssh key, using the provided email as a label. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location. At the prompt, type a secure passphrase.

If you see an existing public and private key pair listed that you would like to use to connect to GitHub, or once you are done with the above key generation step, you can add your SSH key to the ssh-agent with the following commands:

eval "$(ssh-agent -s)"

ssh-add ~/.ssh/id_rsa (Add -K option, if on MAC OS, as it will add the passphrase in your keychain when you add an ssh key to the ssh-agent.)
