In this demonstration we will install git on Oracle Enterprise Linux 9.5
First, create a free account on GitHub. During sign-up, you will be required to provide an email address and a unique username."
I have created my github account with email mahekarthya@gmail.com and username as mahekarthya
Install git on OEL 9.5
[root@devopsvm01 ~]# cat /etc/oracle-release
Oracle Linux Server release 9.5
[root@devopsvm01 ~]#
[root@devopsvm01 ~]# git --version
bash: git: command not found...
Install package 'git-core' to provide command 'git'? [N/y] N
[root@devopsvm01 ~]#
[root@devopsvm01 ~]# dnf install git -y

Verify the git version.
[root@devopsvm01 ~]# git --version
git version 2.47.3
[root@devopsvm01 ~]#
git commit, the value set by this configuration is used as the author name for that commit. This is crucial for tracking who did what in a project's history.Without both a user.name and a user.email configured, Git will not allow you to make commits and will prompt you to set them.
The process involves creating a public/private key pair on your local machine and then uploading the public key to your GitHub account.
To create public/private key pair we use,
ssh-keygen -t ed25519 -C "your-email-id"
-t ed25519 The type flag (-t) specifies the encryption algorithm. ed25519 is a modern, highly secure, and fast elliptic curve cryptography algorithm.
-C "your-email-id"The comment flag (-C) adds a descriptive label to the key.
[root@devopsvm01 ~]# ssh-keygen -t ed25519 -C "mahekarthya@gmail.com"
Generating public/private ed25519 key pair.
Enter file in which to save the key (/root/.ssh/id_ed25519):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_ed25519
Your public key has been saved in /root/.ssh/id_ed25519.pub
The key fingerprint is:
SHA256:ze9xwRCHBSl8IHks9q8ZOn2GxwPVbcCA6tl3315h8Uk mahekarthya@gmail.com
The key's randomart image is:

Go to setting tab,
-T: This option tells SSH not to allocate a pseudo-terminal. For this specific test with GitHub, this is an important flag because you are not trying to execute an interactive shell session, just authenticating.
