Zip several soundfile-formats without deflate

Question

I have a folder that i want to zip but not deflate the soundfiles (since i'll create an expansion file for android).

TO achieve that one can use the -n flag. that is

zip -n .mp3 main_expansion thaisounds

then a new zip-folder is created where the mp3-soundfiles are stored but not deflated.

The problem is that I also have two other sounfile-format there

.wav
.3ga

If I add those as follows

 zip -n .mp3,.wav,.3ga main_expansion thaisounds

Then the program starts to deflate all files though I use the -n flag.

So - my question - How should I use the zip-command to not deflating the mediafiles when there are several formats?

Answer 1

According to my version of the zip man-page, you need to use colons to separate the suffixes:

   -n suffixes
   --suffixes suffixes
          Do not attempt to compress files named with the given suffixes.  Such files are simply stored (0% compres-
          sion) in the output zip file, so that zip doesn’t waste its time trying to compress  them.   The  suffixes
          are separated by either colons or semicolons.  For example:

                 zip -rn .Z:.zip:.tiff:.gif:.snd  foo foo

So you'd end up with:

zip -n .mp3:.wav:.3ga main_expansion thaisounds
