![GitHub release (latest SemVer)](https://img.shields.io/github/v/release/Gatecrasher777/ytcog-dl?style=plastic)  

A command line interface (CLI) for [ytcog](https://github.com/gatecrasher777/ytcog), the YouTube innertube class library for node-js.

From the command line you can:

* Download videos from ids/urls or batch downloads from search, channel or playlist results
* Obtain video information
* Output a stream summary to help choose specific download streams
* Save search results: videos, playlists, channels, movies
* Save channel information and videos, playlists, related channels, or channel search results
* Save playlist information and videos or convert your favorite playlist to an mp3/flac audio library.

Each command line request represents a completed session. 
If you need the added efficiency of a maintained session, you can use the [ytcog innertube library](https://github.com/gatecrasher777/ytcog) directly.
