Remove all from the ID3 tag:

for f in *.mp3; do eyeD3 --remove-all "$f"; done

Given file names like name001.mp3, create new ID3 tag, and set the title to the index of the file:

for f in *.mp3; do i=`echo $f | grep -oP '\d\d\d'`; eyeD3 --to-v2.3 -t $i "$f"; done

The above scripts report the error: "No ID3 v1.x/v2.x tag found!". Ignore it.
