y2mp3v:
#!/bin/sh
./youtube-dl --verbose --extract-audio --audio-format mp3 --restrict-filenames --o "%(title)s.%(ext)s" --batch-file $1

thanks a lot!!

[jaimeMF]

In the script you are calling ./youtube-dl, and I guess that it's not the same executable you run with youtube-dl. You'll have to either update that executable or modify the script.

[00stormy00]

OH! I'm sorry!
You are right, there was another version in the current folder.

Now all works great!
I updated my script to:

#!/bin/sh
/usr/local/bin/youtube-dl --extract-audio --audio-format mp3 --restrict-filenames --o "%(title)s.%(ext)s" --batch-file $1

thanks!!
