So, we move up to the next level in using shell variables (adding parameter expansions to the steps involved):

Code:

for f in *.wav;do mv "$f" "${f%wav}bwf";done

And, concerning your "tiny remark"; we usually recommend that you learn to use vi when editing shell scripts instead of using "pretty-printing editors" like TextEdit. The vi editor may have a steep learning curve, but you will learn all about using regular expressions (that you can use in sed and grep and find) and editing commands that you can use not only in vi but also in sed, shell command history expansions, ed, ex, and cursor motion commands that apply in many other interactive commands, AND you'll get the single-quotes, double-quotes, and back-quotes you need without a pretty-printing editor's thinking that other characters might look prettier but then make your scripts fail miserably since shells don't recognize them as valid syntax.
