Bash script to convert multiple video files to mp3s using ffmpeg.. Don't know if someone already written similar or better script, this is just for my self satisfaction also I'll be glad if it is useful for others

convert_vid.sh

#!/bin/bash

# Script License: GPL
# Dependensies: ffmpeg (You need ffmped installed in your system)
# Usage: "Takes single/multiple file paths as input and converts them to mp3"
# Example: "./convert_vid.sh Downloads/Amsterdam\ Imagine\ Dragons.flv Downloads/BrownRang.mp4" converts 'Downloads/Amsterdam Imagine Dragons.flv' and 'Downloads/BrownRang.mp4' to 'Downloads/Amsterdam Imagine Dragons.flv.mp3' and 'Downloads/BrownRang.mp4.mp3'

if [ $# -gt 0 ]; then
    while test $# -gt 0
    do
        Filo=${1//\ /\\\ };
        echo "
Converting $Filo
Command: ffmpeg -i $Filo -vn $Filo.mp3"
        eval "ffmpeg -i $Filo -vn $Filo.mp3 "
        shift
    done
else
    echo "
Which video file to convert?
Script usage ./convert.sh <video filepath> ...
";
