##### *Q2*: What is the command to write a commit message in Git?
**Difficulty:** ⭐

Use:
```sh
git commit -a
```

 -a on the command line instructs git to commit the new content of all tracked files that have been modified. You can use 
```sh
git add <file>
```
or 
```sh
git add -A
```

before git commit -a if new files need to be committed for the first time.

##### *Q3*: What is Git fork? What is difference between fork, branch and clone?
**Difficulty:** ⭐⭐

* A **fork** is a remote, server-side copy of a repository, distinct from the original. A fork isn't a Git concept really, it's more a political/social idea. 
* A **clone** is not a fork; a clone is a local copy of some remote repository.  When you clone, you are actually copying the entire source repository, including all the history and branches.
* A **branch** is a mechanism to handle the changes within a single repository in order to eventually merge them with the rest of code. A branch is something that is within a repository. Conceptually, it represents a thread of development.

##### *Q4*: What git command do you need to use to know who changed certain lines in a specific file?
**Difficulty:** ⭐⭐⭐⭐⭐

Use `git blame` - a little feature in git that allows you to see who wrote what in the repository. If you want to know who changed certain lines, you can use the -L flag to figure out who changed those lines. You can use the command: 
```sh
git blame -L <line-number>,<ending-linenumber> <filename>
```
