SSH

Create

1) Open Terminal.
2) Paste the text below, replacing the email used in the example with your GitHub email address.
shell ssh-keygen -t ed25519 -C "your_email@example.com"

Note: If you are using a legacy system that doesn’t support the Ed25519 algorithm, use:
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
3) At the prompt, type a secure passphrase.

```
  > Enter passphrase (empty for no passphrase): [Type a passphrase]
  > Enter same passphrase again: [Type passphrase again]
```

Adding your SSH key to the ssh-agent

ssh-add ~/.ssh/id_ed25519

Mac Get Public Key, Copy to clipboard

pbcopy < ~/.ssh/id_rsa.pub

Create Config File

Still in the same terminal, try using ls to see if a file name config exists. If it does, use code config to open it up in your code editor. If it
doesn’t exist, you can create it by using touch
config, then open it with code config. Copy and paste the following in your config:

Example

        # Work account
            Host bitbucket.org
            HostName bitbucket.org
            IdentityFile ~/.ssh/id_rsa_work
            User git
            IdentitiesOnly yes
        # Personal account
            Host github.com
            HostName github.com
            IdentityFile ~/.ssh/id_rsa_personal
            User git
            IdentitiesOnly yes

Errors

Permissions for '/Users/username/.ssh/id_rsa' are too open. It is recommended that your private key files are NOT accessible by others. This private key will be ignored.
If your private key is not-so-private, you can easily fix that.
Use chmod 600 ~/.ssh/id_rsa_work to make it only read-writeable by you.
If you just want to make it readable by
you, then you can use chmod 400 ~/.ssh/id_rsa
I recommend using the 600 over the 400 in this case.
we created a field called Host for each of our SSH keys. In my example, I named them after the website used for source control. If you decided to name yours something else, make sure you reference it when you clone a new repo. Let’s say you decided to do Host personal instead of Host github.com, that means to clone into your github account you would need to use:
```
    git clone git@personal:username/repo-name.git
```

gh cli

use token to authorize and merge

    export GH_TOKEN=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;
    act=$(gh auth status -t >>(tee -a) 2>&1 | sed -n 's/.*Token: //p');
    if [ "$act" == *"$GH_TOKEN"* ](%22$act%22%20==%20*%22$GH_TOKEN%22*.md#)
    then echo $GH_TOKEN | gh auth login --with-token;
    gh repo sync --force;

Tricks & Tips

Use URL for a file on GitHub

use the word ‘raw’ :

https://raw.githubusercontent.com/14paxton/14paxton.github.io/master/assets/images/kubernetes.gif

Example:

      <img
          alt="kubernetes"
          src="https://github.com/14paxton/14paxton.github.io/blob/master/assets/images/kubernetes.gif?raw=true"
      />
