Exploring Git History: Time Travel Made Easy

In the previous parts, we learned the basics of Git, created repositories, and became code-committers. Now, let's go back in time! Git has a fantastic feature called "history," and it's like a magical time machine for your code. Buckle up, and let's dive deep into Git history.

Git Log: Your Time Machine

Imagine you want to see all the changes and who made them in your project. Git's got your back with the git log command. You can use it to check the history of your code and even travel to a specific point in time.

Getting Started with git log

To see the history of a specific file, use:
```
 theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log file1.txt
```
This command will display all the commits related to that file.
To get a complete project history, simply type:
```
 theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log
```
This shows you every commit in your project.

Explore Options with git log

Limit the Number of Commits Shown: Use -n to specify the number of commits to display. For example, git log -n 2 shows the last 2 commits.
- ```
  theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log -n2
```
Filter by Author: If you want to see commits by a specific author, use --author. For instance, git log --author="shubham" will show commits by Shubham.
- ```
  theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log --author="Shubham"
```
Time Travel: You can journey through time using --since and --until to filter commits made between certain dates. For example, git log --since="2016/12/13" shows commits from that date onward.
- ```
  theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log --since="2016/12/13"
```

Search Commit Messages: Use --grep to search for specific keywords or phrases in commit messages. For instance, git log --grep="DB code" will list commits with "DB code" in their messages.
- ```
  theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log --grep="Create"
```
One-Liner Logs: If you prefer a high-level summary, --oneline gives you a condensed view with only commit IDs and messages.
- ```
  theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log --oneline
```

Qn: Find the Unicorn Commits

Let's say you want to find all the magical commits done by a user named "Shubham" that contain the words "Add" in the commit messages.

theshubhamgour@ubuntuM1:~/Desktop/git-hash$ git log --author="Shubham" --grep="Add" -n2

This command will show you the commits that matches the mentiond criteria.

Now you're a Git time traveler, exploring your project's history with confidence. The git log command is your ticket to the past, where every line of code tells a story. Happy coding and time traveling! 🕰️
