Convert a list of YouTube URLs to a single playlist. Open a single tab to watch all the videos instead of opening each video manually.

youtube-playlist

#!/usr/bin/env bash

# Usage:
# Multiple args: $ youtube-playlist https://youtu.be/############ https://youtu.be/############ ... 
# Single delimited arg: $ youtube-playlist 'https://youtu.be/############ https://youtu.be/############ ...'


youtube-playlist() {
  local urls=( $(IFS=$'\n'; <<<"$*" grep -o 'v=.*' | cut -f 2 -d=) )
  local comma_separated="$(IFS=,; echo "${urls[*]}")"
  echo "http://www.youtube.com/watch_videos?video_ids=${comma_separated}"
}
