Out of morbid curiosity (and boredom), I started wondering what types of audio files I had on my systems. I ran "file --mime-type" on 6.8 million files, looked for "audio/whatever" and got the file extensions.
Extension MIME-type --------------------------- .8svx audio/x-aiff .aif audio/x-aiff .aifc audio/x-aiff .aiff audio/x-aiff .ape audio/x-ape .arm audio/amr .au audio/basic .flac audio/flac .m4a audio/x-m4a .mp3 audio/mpeg .mpc audio/x-musepack .oga audio/ogg .ogg audio/ogg .opus audio/ogg .ra audio/x-pn-realaudio .voc audio/x-unknown .wav audio/x-wav If nothing else, it's faster to run "locate" and look for file extensions; running "file" on that much crap took nearly 9 hours. -- Karl Vogel I don't speak for anyone but myself My doctor told me to stop having intimate dinners for four, unless there are three other people. --Orson Welles
