* `Create` a database and table (necessary for the subsequent CRUD operations).
```bash
- $ python3 tasks.py create
+ $ python3 src/tasks.py create
```
* `Drop` the database (and table).
```bash
- $ python3 tasks.py drop
+ $ python3 src/tasks.py drop
```
* `Insert` a new tasks record.
```bash
- $ python3 tasks.py add 'New Task Description'
+ $ python3 src/tasks.py add 'New Task Description'
```
* `Update` a task record's completion field (by specifying the `id` and `completion` value).
```bash
- $ python3 tasks.py update 3 1
+ $ python3 src/tasks.py updateStatus 3 1
```
* `Select` and print all tasks.
```bash
- $ python3 tasks.py show
+ $ python3 src/tasks.py show

* `Delete` a task record (by `id`).
```bash
- $ python3 tasks.py delete 3
