# 🚀 Git Assignment – My Version Control Journey

---

## 🛠 Step 1: Verifying Git Installation

📌 _First step was making sure Git was installed and working fine._

✅ The output displayed the installed Git version.

---

## 📂 Step 2: Checking Repository Status

👀 _Next, I checked the repo to see if there were pending changes._

🔎 Git shows tracked, untracked, and staged files.

---

## ➕ Step 3: Moving Files to Staging

✨ _I noticed some modifications and added them with_ `git add`.

![Git add](git_add.png)

🗂 Files are now ready to be saved in the next commit.

---

## 📝 Step 4: Reviewing Commit History

📖 _Every commit is part of the project’s story, so I reviewed mine._

![Git log](git_log.png)

🕒 Shows commit messages, author names, and dates.

---

## 🔹 Step 5: Simplified Commit Log

👾 _To avoid too much detail, I used_ `git log --oneline`.

![Git log oneline](git_log_--oneline.png)

⚡ A compact and easy-to-read commit history.

---

## 🌳 Step 6: Visualizing History with Graph

🎨 _History is better when visualized, so I used graph mode._

🌿 Displays branches and merges clearly.

---

## 🔍 Step 7: Checking File Changes

🖋 _Before committing, I inspected changes with_ `git diff`.

![Git diff](git_diff.png)

🔑 Shows exact line changes inside files.

---

## 🆚 Step 8: Comparing Two Versions

⚔️ _To see what changed between two commits, I compared them._

![Git diff between two commits](git_diff_commit_commit.png)

📌 Helps track project progress over time.

---

## 🌿 Step 9: Working with Branches

🔀 _I explored branches to work independently without touching main code._

![Git branch](git_branch.png)

🌱 Branches allow experimentation safely.

---

## 📥 Step 10: Cloning a Repository

🛰 _I downloaded a project from remote using_ `git clone`.

![Git clone](git_clone.png)

📂 A full copy is now available locally.

---

## 📥 Step 11: Pulling Remote Updates

🛰 _To stay up to date, I fetched and merged with_ `git pull origin`.

![Git pull](git_pull.png)

---

## 🌐 Step 12: Checking Remote Connections

🔗 _I verified linked remote repositories with_ `git remote -v`.

![Git remote](git_remote.png)

---

## 🚫 Step 13: Using .gitignore

📄 _Added a `.gitignore` file to skip tracking unnecessary stuff._

![Git ignore](gitignore_file.png)

---
## 🔀 Step 14: Performing a Merge

⚡ _I merged changes from another branch into my current branch._

![git log --merge](git_log_--_merge.txt.png)

📌 Since both branches had commits, Git created a **3-way merge commit** (not a fast-forward merge).

---
## 📜 Step 15: Inspecting Merge Commit Details

👀 _I used `git log -p -- merge.txt` to review the merge commit changes._

![git log -p -- merge.txt](git_log_-p_--_merge.txt.png)

📝 Shows added and modified lines from both branches.

---
## 🗂 Step 16: Checking Simplified Log After Merge

⚡ _To quickly see the commit history after the merge, I ran:_

![git log --oneline -- merge.txt](git_log_--oneline_--_merge.txt.png)

---
## 🌳 Step 17: Visualizing All Branches and Merge

🎨 Using the graph mode to visualize history clearly:

![git log --graph --oneline --all](git_log_--graph_--oneline_--all.png)

🌿 Shows both branches and the merge commit.

---
## Step 18: Blame – Tracking Line History

🖊 With git blame, I checked who wrote each line in merge.txt.

![git blame merge.txt](git_blame_merge.txt.png)

🔑 Each line is attributed to its commit.

---
## 🎯 Step 19: Blame with Line Range

🎯 To narrow focus, I ran blame only for lines 1–5.

![git blame -L 1,5 merge.txt](git_blame_-L_1,5_merge.txt.png)

---

## 📧 Step 20: Blame with Email

📧 Finally, I checked the author emails using git blame -e.

![git blame -e merge.txt](git_blame_-e_merge.txt.png)

---
## 🔀 Step 21: Merging Branch `feature/mergeFile` into Main

⚡ _I merged the branch `feature/bugReport` into `feature/mergeFile` using the command:_

![git merge feature/mergeFile](git_merge.png)

---
