Git Commmands¶

Setting Up a Repository¶

Initialize a new Git repository:
```
git init
```

Clone an existing repository:

git clone https://github.com/user/repo.git

Basic Workflow¶

Check the status of your repository:
```
git status
```

Add changes to the staging area:

git add filename
# or add all changes
git add .

Commit changes:
```
git commit -m "Commit message"
```

Branching and Merging¶

Create a new branch:
```
git branch new-branch
```
Switch to a different branch:
```
git checkout new-branch
```
Create and switch to a new branch:
```
git checkout -b new-branch
```
Merge a branch into the current branch:
```
git merge branch-to-merge
```

Remote Repositories¶

Add a remote repository:

git remote add origin https://github.com/user/repo.git

Set the remote URL with a token (as per your example):

git remote set-url origin https://$GITHUB_TOKEN@github.com/yuva19102003/portfolio.git

Push changes to a remote repository:
```
git push origin main
```
Pull changes from a remote repository:
```
git pull origin main
```
Fetch changes from a remote repository (without merging):
```
git fetch origin
```

Viewing History¶

View commit history:
```
git log
```
View a summarized commit history (one line per commit):
```
git log --oneline
```

Undoing Changes¶

Unstage a file:
```
git reset HEAD filename
```
Revert changes in a file to the last committed state:
```
git checkout -- filename
```
Revert a specific commit:
```
git revert commit-hash
```

Stashing Changes¶

Stash changes:
```
git stash
```
List stashed changes:
```
git stash list
```
Apply stashed changes:
```
git stash apply
```

Working with Tags¶

Create a new tag:
```
git tag -a v1.0 -m "Version 1.0"
```
Push tags to the remote repository:
```
git push origin --tags
```

Example Workflow¶

Let's go through a typical workflow using some of these commands:

Clone a repository:

git clone https://github.com/yuva19102003/portfolio.git
cd portfolio

Create a new branch:
```
git checkout -b new-feature
```
Make changes to files and add them to the staging area:
```
git add .
```
Commit your changes:
```
git commit -m "Add new feature"
```
Push your changes to the remote repository:
```
git push origin new-feature
```
Switch back to the main branch:
```
git checkout main
```
Merge the new feature branch into the main branch:
```
git merge new-feature
```
Push the updated main branch to the remote repository:
```
git push origin main
```

This workflow demonstrates how to clone a repository, create and switch branches, make and commit changes, and push those changes to a remote repository.
