To copy a `.rar` file using the command line, you can use the `cp` command in a Unix-like operating system (like Linux or macOS). Here’s how you can do it:
### Basic Syntax
```bash
cp /path/to/source/file.rar /path/to/destination/
```
### Example
If you have a `file.rar` in your current directory and you want to copy it to a folder called `backup` (which is also in your current directory), you would use:
```bash
cp file.rar backup/
```
