How to download your Youtube videos using command line

1. Download your version of youtube-dl from https://youtube-dl.org/

2. For Windows 10, download the file https://github.com/ytdl-org/youtube-dl/releases/download/2021.12.17/youtube-dl.exe
3. Copy the file youtube-dl.exe into the d:\youtube-dl\ directory
4. To download a youtube video, open a Windows Powershell and run: 

Examples:
PS D:\youtube-dl> .\youtube-dl.exe https://www.youtube.com/watch?v=pChVWAVY7RU 
PS D:\youtube-dl> .\youtube-dl -o " d:/youtube-dl/Downloads/%(title)s" http://www.youtube.com/watch?v=rnvK2TIhYns


Note:
1. For documentation , please check https://github.com/ytdl-org/youtube-dl/blob/master/README.md
2. For help, run: youtube-dl -h
3. Use the -o option with youtube-dl to manually give a location for the downloaded files:

youtube-dl -o "~/Desktop/%(title)s.%(ext)s" 'youtube file url'
and of course substitute your actual url for 'youtube file url'. This example sends the completed download to your Desktop.

4. Create a configuration file for youtube-dl as follows:

touch ~/.config/youtube-dl.conf
Then set a default download location in this file:

--output "~/Desktop/%(title)s.%(ext)s"
With this in place all downloaded files will automatically go to your Desktop.
