Motivation:

You want to use Git to version your files or share your files with other people.

Solution:

• Register a GitHub or a GitLab account.
• Create a GitHub repository or a GitLab project.
• Download and install a Git client.
• Push a folder with files to the server.

mkdir "D:\NETCORE"
git init
git add *.*
git commit -m "add initial files"
git remote add origin https://github.com/huybien/asp.net-core.git
git push -u origin master

• Push changes to a remote repository.

git add .
git commit -m "CP form"
git push -u origin master

• Update (fetch and merge) a local repository.

git pull

• Force updating (fetch and overwrite) the current repository.

git fetch --all
git reset --hard origin/master
git clean -fd
git pull

• Force updating (fetch and overwrite) a local repository (e.g. C:\Users\admin\Downloads\code).

git -C C:\Users\admin\Downloads\code fetch --all
git -C C:\Users\admin\Downloads\code reset --hard origin/master
git -C C:\Users\admin\Downloads\code clean -fd
git -C C:\Users\admin\Downloads\code pull

• Pull (checkout) a remote repository (e.g. https://github.com/huybien/asp.net-core.git) to an empty local folder (e.g. C:\Users\admin\Downloads\code).

cd C:\Users\admin\Downloads\code
git init
git remote add origin -f https://github.com/huybien/asp.net-core.git
git pull origin master
or
git pull origin main

• Reset (Revert) a local repository to a previous version.

cd C:\Users\admin\Downloads\code
git log --oneline
git reset --hard 4355842
where 4355842 is a version id.
