# Command line interface (CLI)
**Description**
A simple command line interface for working with CVAT tasks. At the moment it
implements a basic feature set but may serve as the starting point for a more
comprehensive CVAT administration tool in the future.
Overview of functionality:
- Create a new task (supports name, bug tracker, labels JSON, local/share/remote files)
- Delete tasks (supports deleting a list of task IDs)
- List all tasks (supports basic CSV or JSON output)
- Download JPEG frames (supports a list of frame IDs)
- Dump annotations (supports all formats via format string)
**Usage**
```bash
usage: cli.py [-h] [--auth USER:[PASS]] [--server-host SERVER_HOST]
[--server-port SERVER_PORT] [--debug]
{create,delete,ls,frames,dump} ...
Perform common operations related to CVAT tasks.
positional arguments:
{create,delete,ls,frames,dump}
optional arguments:
-h, --help show this help message and exit
--auth USER:[PASS] defaults to the current user and supports the PASS
environment variable or password prompt.
--server-host SERVER_HOST
host (default: localhost)
--server-port SERVER_PORT
port (default: 8080)
--debug show debug output
```
**Examples**

`cli.py create "new task" --labels labels.json local file1.jpg file2.jpg`
- Delete some tasks
`cli.py delete 100 101 102`
