Essential Git Commands for Managing Projects on an AWS EC2 Linux Server

Here are some commonly used Git commands tailored for working with a Git repository on an AWS EC2 Linux server:

Install Git (if not already installed):

sudo apt update
sudo apt install git -y

Configure Git (Set global username and email):

git config --global user.name "Your Name"
git config --global user.email "[email protected]"

Clone a repository:

git clone https://github.com/username/repository.git

Clone a private repository using SSH:
- First, add your SSH key to the server:
```
ssh-keygen -t rsa -b 4096 -C "[email protected]"
```
  Copy the public key (~/.ssh/id_rsa.pub) and add it to your GitHub account under SSH keys.
- Then, clone using SSH:
```
git clone [email protected]:username/repository.git
```

Check the repository status:
```
git status
```
Add changes to staging:
```
git add .
```
Or add specific files:
```
git add file_name
```
Commit changes:
```
git commit -m "Your commit message"
```
Push changes to the remote repository:
```
git push origin branch_name
```
Pull updates from the remote repository:
```
git pull origin branch_name
```

List all branches:
```
git branch -a
```
Create a new branch:
```
git checkout -b new_branch_name
```
Switch to another branch:
```
git checkout branch_name
```
Delete a local branch:
```
git branch -d branch_name
```
Push a new branch to the remote repository:
```
git push origin new_branch_name
```

Add a new remote repository:

git remote add origin https://github.com/username/repository.git

View commit history:
```
git log
```
Reset changes (unstaged changes):
```
git checkout -- file_name
```
Undo the last commit (but keep changes staged):
```
git reset --soft HEAD~1
```
Undo the last commit (and discard changes):
```
git reset --hard HEAD~1
```

These commands will help you manage your Git workflow on an AWS EC2 Linux server.
