# GitHub Commands
Git is a type of Version Control System (VCS) that helps developers to work together and maintain a complete history of their work.
Listed below are the functions of a VCS:
* Allows developers to work simultaneously.
* Does not allow overwriting each other’s changes.
* Maintains a history of every version.
Git allows groups of people to work on the same documents (often code) at the same time, and without stepping on each other's toes. It's a distributed version control system.
To clone a remote repository
```
git clone
```
To check what branch you're on:
```
git branch
```
To check all branches on repo:
```
git branch -r
```
To make new branch:
```
git branch
```
To switch to branch:
```
git checkout
```
To get new changes:
```
git fetch --all
```
To check differences between last commit and current changes:
```
git diff
```
To get changes from GitHub to local
```
git pull origin
```
To rebase changes from master onto your branch. Get latest updates while still working on your branch. Normally ONLY DO THIS WHEN YOU JUST DO FRESH COMMIT ON YOUR BRANCH. Otherwise you will get merge errors.
```
git fetch --all
git checkout master
git pull origin master
git checkout
git rebase origin/master
```
If you get merge errors, follow the special command down there and above steps again.
To view commit history
```
git log
```
## To upload changes to your branch on GitHub
Step 1 (Add files)
```
git add
```
Step 2 (Check to ensure the files are correct)
```
git status
```
Step 3 (Commit files to history)
```
git commit -m "Add message here"
```
Step 4 (Push to branch)
```
git push origin
```
## To merge changes from branch into master branch
Go on GitHub and submit a pull request
## To merge changes from master into your working branch
MAKE SURE you are on your branch (do git branch to make sure)
```
git merge master
```
## To avoid having to enter credentials every time (enter both commands)
```
git config credential.helper store
```
then enter this:
```
git config --global credential.helper 'cache --timeout 7200000000000'
```
## Special commands (BE CAREFUL)
To reset EVERYTHING inside the entire project back to the latest commit. VERY VERY useful when you try to do some experiment and you screw up the project. It's like system restore for github project. BE VERY CAREFUL WHEN USING IT. IT WILL WIPE PERMANENTLY AND YOU CANNOT REVERT.
```
git reset --hard HEAD
```
