**Fast-forward (Does not generate merge commit)**

```

#### Fetch latest branch from remote

```
git fetch -p
```

This command will create and switch to new branch

**Method 1**

```

#### Create new branch & copy content from a remote branch

#### Delete branch remotely

This command will delete a branch remotely

```
git push origin --delete <<branch_name>>
```

#### Go back to a specific commit

This command will create a commit and go back to specific commit. Yes, this method will leave the records instead of delete it completely from repo. However, this method is a lot **safer** than `git reset`, especially you're working with other people.

```
git revert <<commit_hash>>
```

#### Squash X commits into 1

This command will let you go back X commits by resetting git index to before the commits you want to squash. Use `--soft` so that git only resets the index and doesn't touch your working directory. Then create a commit as usual. [source from stackoverflow](https://stackoverflow.com/a/50302458/10868150)

```
git reset --soft HEAD~<<X>> // go back X commits
git add --all // Add the changes
git commit 
git push --force 
```

This command will show existing remotes of the project.

```
git remote -v
```

#### Update origin's remote url

This command will update project's origin remotes with new remote url.

```
