## diff
### Show Color Side by Side Diff
```bash
diff --color=always --minimal --side-by-side file1 file2
```
- Shows **red**/_green_ diff of 2 files side by side
- `file1` is the first arg and so it is on the left
- `file2` therefore is on the right
Write diff output to a file
```bash
diff --color=always --minimal --side-by-side file1 file2 > output_file.diff
```
