Ubuntu :: Remove Directories That *don't* Contain A File - Safe Testing Method?

I'm trying to clean up an iTunes-sorted Music directory. For whatever reason, it contains a large number of folders that have album art, but no music. I'm actually more concerned about a safe way to test my removal batch, but I thought I'd paste everything I did in case it's useful to someone. Based on this thread, I came up with the following script:

Code:
#!/bin/bash
find ./*/* -type f -iregex ".*(mp3|m4a)" | sort | while read line ; do
echo "${line%/*}" >> file1
done
sort -u file1 > fileuniq

[Code]...

But I'm scared to just run this on my music folder. Is there any way to run rm in "test mode", so that I would just see verbose output, but it wouldn't actually delete anything? Failing that, does anyone see anything wrong with my plan?
