GIT is a free and open-source version control system that developers widely use for managing small or large projects. It allows multiple developers to work together on nonlinear development, as it tracks changes in source code for each branch of our project’s history. The following tutorial will teach you how to install the latest or upgrade GIT on Rocky Linux 9 or Rocky Linux 8 using the command line terminal, basic commands, and tips.

Update Rocky Linux – Upgrade System Packages
First, update your system to ensure all existing packages are up to date.
sudo dnf upgrade --refresh
Install GIT with Default Appstream
By default, GIT is present and always up-to-date on Rocky Linux, making the installation straightforward by running the following command.
sudo dnf install git -y
GIT Configuration & Setup
The following parts will cover some typical setups and commands used daily by users of GIT.
GIT Add user
After installation, you must set up standard settings such as names and e-mails, mainly around git commit messages. This is pretty straightforward, as the tutorial will explain below.
The first step is to provide your name that will be set Globally.
git config --global user.name "YOUR NAME"
Next, select your e-mail; this can be fake if you prefer.
git config --global user.email "YOUR EMAIL"
GIT Create Directory
First, create a directory for users who want to make a new directory strictly for GIT.
mkdir example-directory -p
Next, navigate to the directory.
cd example-directory -p
The next task is to use the initialization command, creating a hidden .git directory to store the configuration, history, and so on.
You will see a terminal output stating the status of the directory being initialized, and you can additionally see the content using the following command.
ls -a .git
Print GIT CONFIG Details
To confirm GIT config users and details, use the config –list command
git config --list
Unless specified, Git stores details in the ~/.gitconfig file. You can review what is currently stored by using the cat command.
The sudo command with the git config command will set two separate user names and e-mails.
Store GIT Credentials
For users who want to keep authorization details stored, you can enable the credential helper cache using the following.
git config --global credential.helper cache
If you must use credential helper, it is advised to cache only for a limited time for increased security. For example, if you will be working today using GIT for 1 to 4 hours but won’t be touching it for maybe a few weeks, then set the expiry for 5 hours.
git config --global credential.helper "cache --timeout=18000"
After 5 hours, the credentials will be deleted, securing your GIT.
Check Directory GIT Status
To view the status of a GIT repository, you can use the following git status command.
While the above command helps with giving a status of the GIT, you can additionally list all git commands and sub.
Connect Remote GIT Repository
For users that need to work with GIT remotes to sync and download/upload changes, you will need to link the GIT. This can be done using the git remote command as follows.
git remote add origin remote-repository-link
Commit GIT Changes
When you have completed changes in your GIT directory and want to SYNC it to push to the remote repository, use the following git commit command.
git commit -m "git message changelog"
Note the -m “git message change” is the message that appears in the changelog.
Push GIT Changes
To push or send changes to the remote repository to SYNC in both versions, use the following
git push origin master
Pull GIT Changes
Alternatively, to pull or get changes from the remote repository to SYNC in both versions, use the following git push command.
git pull origin master
