# Learning git

## Removing Files

Removing a file with command `rm file` from your working directory, it will be `unstaged`.

`git rm` will remove the file from your tracked files.

To keep the file in your working tree but remove it from your staging area, use the `--cached` option.

```
git rm --cached README
```

## Moving Files

```
git mv file_from file_to
```

Equivalent form is:

```
mv README.md README
git rm README.md
git add README
```

## Undoing Things

### commit amend

The `git commit --amend` command modififes your latest commit. This command lets you change files in your last commit or your commit message. Your old commit is replaced with a new commit that has its own ID.

To change commit message:

```
git commit --amend -m "feat: Revised commit message"
```

To add modified file:

```
git commit --amend --no-edit
```
