Git is a version control system that records changes to files over time, allowing users to recall specific versions. It is a distributed system where each local repository has a full copy of the project files and history, allowing offline work. Users can clone repositories locally or remotely. Files are added and committed with messages to save snapshots, and commits can be visualized. Changes are pushed to remote repositories to share work, and branches allow independent lines of development that can be merged together. Tags mark important commits, and errors can be fixed by resetting files or the repository state.

2. What is version control??
System that records change to file or set
a files over time so that you can recall
specific versions later.

• Distributed Version Control
• Thinks about its data
• Thinks of its data more like snapshots of a miniature of filesystem
• Only need local files and resources to operate.

4. How to clone a repository?
• To create a copy of a local repository:
git clone /local/repository
• To create a copy of a remote repository:
git clone user@server:/server/repository

5. How to add and confirm files
• To add changes in files:
git add <file> ( for only file)
git add * ( all changed files – untracked)
• To confirm all changes , it is necessary to create a commit:
git commit -m “comments about the commit”
git commit -a -m “comments about the commit” (git add + git commit –m)

6. How to visualize your commit
• To show all commits in your branch:
git log

7. How to send changes to a remote repository
• When you have your project at a point that you want to share, you
have to push it upstream.
git push origin master
PS: This command works only if you cloned from a server to which you
have write access

8. Working with branches
• To visualize local branches:
git branch
• To visualize local/remote branches:
git branch –all

9. Working with branches
• To create a branch:
git checkout –b “new_branch”
• To switch between branches:
git checkout <branch_name>
• To remove a branch:
git checkout –d new_branch

10. Working with branches
• To update the local repository
git pull
git pull –rebase (update and put your commits in the HEAD)
• To merge all changes between branches: (I didn’t understand this…)
don’t known what write
git checkout master
git merge <branch>

11. Creating Tags
• To create a tag:
git tag <tagversion> <hash>
• To view all tags:
git tag

12. Fixing errors
• To correct all changes in local files:
git checkout -- <file>
• To remove all changes and return to a stable commit:
git reset – hard
git reset –hard <hash> hash with stable commit
Or
git fetch origin
git reset –hard origin/master
