Bash Script Options?

[RATM_Owns]

I'm making a simple YouTube video to MP3 script (in bash) and is there any way that if I enter
[quote]yt2mp3 --keep-vid[/code]
It will also keep the downloaded YouTube video?

Current script:

#!/bin/bash
echo "Enter the URL of the YouTube video to start downloading."
read VIDEO
echo "Downloading..."
rm -rf "tmp.flv"
youtube-dl $VIDEO -o "tmp.flv"
clear
echo What is the artist of the song?
read ARTIST
echo
echo What is the name of the song?
read NAME
echo
ffmpeg -i "tmp.flv" "${ARTIST} - ${NAME}.mp3"
rm -rf "tmp.flv"
echo
echo "YouTube video converted! Yay!"

read VIDEO
echo "Downloading..."
rm -rf "tmp.flv"
youtube-dl $VIDEO -o "tmp.flv"
clear
echo What is the artist of the song?
read ARTIST
echo
echo What is the name of the song?
read NAME
echo
ffmpeg -i "tmp.flv" "${ARTIST} - ${NAME}.mp3"
if [ "$1" != "--keep-vid" ] ; then
    rm -rf "tmp.flv"
fi
echo
echo "YouTube video converted! Yay!"

I recommend changing:

ffmpeg -i "tmp.flv" "${ARTIST} - ${NAME}.mp3"

to

ffmpeg -i "tmp.flv" -acodec copy "${ARTIST} - ${NAME}.mp3"

Now ffmpeg will copy the mp3 audio stream instead of re-encoding it. This will be faster and will preserve the quality.
