WavPack 4.0 Beta Release 3 Reply #25 – 2004-07-02 15:16:56 QuoteHmm, yes wavpack "*.wav" does work. But what's the difference? (or where can I read about that?)The difference is that in the first case the shell resolve the wildcard and then passes all the matching files to the program. In the second case it passes the wildcard to the program. The wavpack command-line apps only support the later.I can't test your script from here. But at least you should replace /bin/bash by /bin/sh. On most systems it's the same, but it's cleaner this way.
