Github is a collaboration platform built on top of git
To get started with Git download git from
Configuring Git
Copied!git config --system git config --global git config --local
Configure user name email for git
Copied!git config --global user.name "<username>" git config --global user.email "<useremail>" git config --global core.editor "atom --wait" git config --global color.ui true git config --list
Let's write some git commands
| Command | Explanation |
|---|---|
$ git init | Initialize git in your directory |
$ git add <filename> | Add changes to the staging index |
$ git commit -m "<Commit message>" | Commit the changes to the git repository |
- Commit Message
- A short -single summary (less than 50 characters)
- Good if the commit is in present tense
| Command | Explanation |
|---|---|
git clone <url> | Git clone is used to clone a remote repository into a local workspace |
git push | Git push is used to push commits from your local repo to a remote repo |
| git pull | Git pull is used for fetch the newest updates from a remote repository |
$ git branch | Used to manage branches |
$ git branch <branch name> | Creates the branch |
$ git branch -d "<branch name>" | Deletes the branch |
$ git branch -D "<branch name>" | Forcibly deletes the branch |
$ git checkout "<branch name>" | Switches to a branch |
$ git checkout -b "<branch name>" | Creates a new branch and switches to it. |
$ git merge "<branch name>" | Merge joins branches together |
$ git merge -abort | If there are merge conflicts (meaning files are incompatible). --abort can be used to abort the merge action |
$ git log --graph --oneline | This shows a summarize view of the commit history for a repository. |
Show the difference in the tracked files

|---|---|
git show | git show is used to show the changes in the head of master commit |

git remote show <name> | Describes a single remote repo |

| git branch -f | Lists remote branches: can be combined with other branch arguments to manage remote branches |
| git log -p | Produces patch text |
