- What is Git and Version Control
Assignment:
-Write down (in your own words) what problem Git solves.
-Find one real-life example where multiple people edit the same file (school project, code, Google Docs).
-Answer: Why is version control better than emailing files back and forth?
--Git is mainly created to keep (1)control of version history especially during development - it makes sure nothing is lost due to human error and helps keep track of changes and by who. This is important to (2)ensure efficiency during any project - takes up lesser time to fix errors and go back and forth between versions if necessary. Files are also (3)accessible remotely and doesn't require a specific device.
--Examples: Group projects presentations, research papers worked on by multiple people
--Emailing back and forth takes a lot of disk space and memory as opposed too version control that keeps track of specific changes and times. Emailing back and forth requires manual intervention to keep track of version, prone to error and confusion, sometimes data could get lost in the pile. Git is not managed by a singular person, which makes sure all files are accounted for and treated the same - makes it easier to look back and understand the process each version or file went through because they all underwent the same set of file managment rules.
- Installing Git & Configuring User Info(COMPLETED)
Assignment:
Install Git (if not already installed).
Run:
git --version
git config --global user.name "Your Name"
git config --global user.email "your@email.com"

git config --list
- Initializing a Repository
Assignment:
Create a new folder git-practice-<<your_name>>.
Inside, run:
git init
Verify that a .git folder is created.
Run git status and note the message (it should say “No commits yet”).
mkdir git-practice-Mag
git init
ls -a verify folder
git status nothing added to commit but untracked files present (use "git add" to track)
- Working Directory, Staging, and Commits
Assignment:
In git-practice-<<your_name>>, create a file notes.txt.
Run:
git status
Observe which area (untracked → staged → committed) the file is in as you do:
git add notes.txt git commit -m "Add first notes file" git status
Write down how the status changed after each command.
cd git-practice-Mag go to Directory
touch notes.txt creates file
git status notes.txt in the list of yet to be commit
git add notes.txt
git status notes.txt commit, doesnt show up in the list
git commit -m "Add first notes file"
Magdel@LAPTOP-NS5FVUS9 MINGW64 ~ (master) $ git commit -m "Add first notes file" [master (root-commit) 5287a29] Add first notes file 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 notes.txt
git status
- Adding & Committing Files
Assignment:
Add another file todo.txt.
Stage and commit with a meaningful message.
Modify todo.txt, then commit the change again.
Run git log --oneline to see both commits.
cd git-practice-Mag
touch todo.txt
git add todo.txt stage
git commit -m "List of tasks you need to complete" commit
Magdel@LAPTOP-NS5FVUS9 MINGW64 ~/git-practice-Mag (master) $ git commit -m "List of tasks you need to complete" [master 3a3ab4d] List of tasks you need to complete 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 git-practice-Mag/todo.txt
echo "Task 1" >> todo.txt modify text git add todo.txt git commit -m "Add a task" commit changes
Magdel@LAPTOP-NS5FVUS9 MINGW64 ~/git-practice-Mag (master) $ git commit -m "Add new task" [master b8c2503] Add new task 1 file changed, 1 insertion(+)

- Viewing Commit Logs & Diffs
Assignment:

git log
git log --oneline --graph
