OT: Batch converting .flv to .mp3 using ffmpeg

[Nigel Ridley]

My daughter has given me a nice job :-)!
She wants me to convert about 30 flash movie clips to MP3. At the moment I can do them 
individually using the following:

ffmpeg -i name_of_video_clip.flv -vn name_of_file.mp3

How can I convert a batch of them at the same time?

I know it must be possible as I use the following to batch covert jpg's (for my daughters' 
facebook accounts):

for i in *.JPG; do montage -geometry 450x600  -quality 75 $i -$i; done

Blessings,

Nigel
