## CLI Usage
```sh

By default, Multitask cli will reads a file in `Tasks.json` or `Tasks.js` for Tasks list. 

Each task is written in Array format. `Tasks.json` sometime can looks like this:

```json
[
	["echo", ["Hello World"]],
	["pwd", [], {

		"shell": true
	}]
]
```
This will result:
```
Hello World
___________________________________
/home/username
```
