This is an strightforward way to download a whole playlist from youtube:

I have tried different scripts and packages but I always get many error.
So I came up with this solution:


First of all you need to have youtube-dl installed on your machine,
🖥 Debian:
$ sudo apt install youtube-dl
💻 Mac:
$ brew install youtube-dl

Replace PLAYLIST-URL with a url of your interested one:

in 💾 script.sh
———————————————

youtube-dl --get-id PLAYLIST-URL -i > urls.txt
input="urls.txt"
while IFS= read -r line
do
youtube-dl -c -f 22 "https://www.youtube.com/watch?v=""$line" &
done < "$input"

———————————————
videos are downloaded in parallel at the backgound. Do not close the terminal.
if you want to close the terminal put a nohup at the begining of the command.

chmod +x script.sh # to make executable
nohup ./script.sh. # to run in background

22 in commends control the quality of the video. If you need more options use
$youtube-dl -F VIDEO-URL
to select a proper option.
usually 22 is for the best and 18 is for lower quality.


#bash
#youtube-dl
#download

Anyway ther are other options to use youtube-dl:

Getting the name of the variable using the variable.

Guess the output (no cheating):
False == False in [False]

then you can check the answer from an online Python interpreter.


if you are surprised by the answer, look at "chained comparison" in Python.

rsync also check for the presence of file at the destination, so can prevent duplicate transfer.

This one also works :

$ conda install -c anaconda cudatoolkit

for a specific version say 11.0:

$ conda install -c conda-forge cudatoolkit=11.0

conda forge is just a channel.
