This goes with the previous post concerning converting files from flac to mp3. Sometimes filenames have characters beyond spaces that make it difficult to work with in a script. If you want to rename your files without annoying special characters, use the following command.
for f in * do mv "$f" $(echo $f | sed -e 's/[^A-Za-z0-9._-]/_/g') done
This will replace every non-alphanumeric character in the filename with an underscore _
