## Usage

```typescript
import { commandJoin } from "command-join"
```

### `commandJoin(arg: string | string[]): string`

Escapes each command-line argument and joins them into a string that can then be executed, e.g. via `child_process.exec`.

If a string is passed, an array containing the string will instead be processed.

**Example**

```javascript
const command = commandJoin(['a', "b\\", "'c"])
command
// output on Windows: a "b\\" 'c
// output on Linux: a 'b\' \'c
```

See the tests for more convoluted examples.
