# Committing Pushing

### Committing/Pushing

```bash
$ git add .
$ git commit
$ git push
```

### Fix a commit

```bash
$ git commit -amend
```

### Reset to last git commit

```bash
$ git reset --hard HEAD
# OR
$ git reset --hard
```

### Undo a commit without losing local files

```bash
git reset HEAD~1
```

### Commit specific lines of code

```bash
$ git add -p
>> Stage this hunk [y, n, ...]?
```

* Pick the chunks of code you do want to commit
* stage this hunk means are you gonna commit this?

#### Options for `Stage this hunk [y, n, ...]?`

* Press `?` if you want more info
* Press `n` to go to next change

**Note**: Does not work for new files (i.e. if you do a `touch`, and try to do `git add -p` right after)

### Delete file that is already in repo

```bash
$ git rm <file-name> 
```

* If you want to delete this file that is already in the repo, use this to not commit file-name

### Show changes between commits

```bash
$ git diff
```

* when you do `y` for `git add -p`, `git diff` will be empty (obviously)

### Do not commit specific lines of code

```bash
$ git reset -p
```

## `.gitignore`

* Checking if something's really ignored
  * do `git status` and check if file still appears as red
* Ignoring all types of a file extension, folder, or file
  * `*.<file-extension>` (eg. txt, swp)
  * `*<folder/file-name>`

### Get latest commit hash

```bash
git rev-parse origin/<branch_name>
```

### Get commits different between two branches (parent and child)

```bash
git log <parent_branch>..<child_branch>
```
