debian 13.1, yt-dlp stable@2025.11.12 from yt-dlp/yt-dlp, updated with yt-dlp -U
I also installed deno on the terminal with curl -fsSL https://deno.land/install.sh | sh
however, nothing happens if I execute yt-dlp, like: yt-dlp --all-subs --no-warnings https://www.youtube.com/watch?v=1bhuN9nqEb4 returns nothing.
All my terminal shows after executing a command like the one pasted I get:
>
that’s it, a > and nothing else.
Am I doing something wrong?


That prompt typically means the command line is expecting more. Try putting the url in quotes. That may fix it.
The reason this might work is that some shells, like zsh, interpretes the questionmark in the URL as a function of some sort, making the URL invalid to yt-dlp.
