Youtube Video Downloader

Instead of everytime dealing with youtube downloader websites, actually you can download it yourself. With this bash script you just need to enter the id of a youtube video or playlist, and you can download it.

1. You need to download yt-dlp 2. I am using mac, so just copied yt-dlp binary to /usr/local/bin folder.

1. Install yt-dlp with homebrew
2. Append the code below to your ~/.zprofile file. (Or which ever bash file that suits you)

Usage

For downloading a video copy the video id and execute it like this:

ytv dQw4w9WgXcQ

Or you can download just the audio

yta dQw4w9WgXcQ

You can use it for youtube playlists as well.

ytp PLv1AUcJnyG9vMwxGQUDdWUFYoBownaUnp

Anatomy of a youtube link

• Video ID in a youtube link /watch?v=aDaOgu2CQtI
• Playlist ID in a youtube playlist /playlist?list=PLv1AUcJnyG9vMwxGQUDdWUFYoBownaUnp

Explanation of parameters

Playlist function also creates a folder for each item in the playlist.

yt-dlp -o '%(playlist)s/%(playlist_index)s - %(title)s/%(title)s.%(ext)s' \

• %(playlist)s Playlist name
• %(playlist_index)s Position number in playlist.
• %(title)s Video title
• %(ext)s Extension of the video.

Additionally you can make some changes for the final file name. This line below for replacing words, extra spaces etc.
