6.3 Getting Started with Git

6.3.2 Exercises

1. Start a repository in a new directory.

   $ mkdir new_directory
   
   $ cd new_directory
   
   $ git init

2. Create a new file in your new Git repository. Make sure Git is tracking the file and then create a new commit.

   $ touch new_file.txt
   
   $ echo "This is a new file" > new_file.txt
   
   $ git add new_file.txt
   
   $ git commit -m "Added a new file"

3. Make changes to the file, and then commit these changes.

   $ echo "This is the second line in the new file" >> new_file.txt
   
   $ git add new_file.txt
   
   $ git commit -m "Edited the new file"

4. Add two new files to your repository, but only commit one of them. What is the status of your repository after the commit?

   $ touch file1.txt file2.txt
   
   $ git add file1.txt
   
   $ git commit -m "Added another one file"
   
   $ git status # Output:

   Untracked files:
     (use "git add <file>..." to include in what will be committed)
   
       file2.txt    
   

5. Undo the last commit, add the untracked file, and redo the commit.

   $ git reset --soft HEAD~ # or HEAD~1
   
   $ git add -A
   
   $ git commit -m "Added another two files"
