man bash:
Quote:
${parameter#word}
${parameter##word}
Remove matching prefix pattern. The word is expanded to produce a pattern just as in pathname expansion. If the pattern matches the beginning of the value of
parameter, then the result of the expansion is the expanded value of parameter with the shortest matching pattern (the ``#'' case) or the longest matching pat”
tern (the ``##'' case) deleted.

The inner ${FN%%[[:alpha:]]*} removes all chars from the first alpha to string end, then ${FN#...} uses the result to remove the leading digits, no matter how many.

oggz-merge(1)						      General Commands Manual						     oggz-merge(1)

NAME
oggz-merge -- Merge Ogg files together, interleaving pages in order of presentation time. SYNOPSIS
oggz-merge [-o filename | --output filename ] filename ... oggz-merge [-h | --help ] [-v | --version ] Description oggz-merge merges Ogg files together, interleaving pages in order of presentation time. It correctly interprets the granulepos timestamps of Ogg CELT, CMML, Dirac, FLAC, Kate, PCM, Speex, Theora and Vorbis bitstreams. Run oggz-known-codecs(1) for a full list of codecs known by the installed version of oggz. For example, if you have an Ogg Theora video file, and its soundtrack stored separately as an Ogg Speex audio file, and you can use oggz- merge to create a single Ogg file containing the video and audio, interleaved together in parallel. Similarly, using oggz-merge on a collection of Ogg Vorbis audio files will create a big Ogg file with all the songs in parallel, ie. inter- leaved for simultaneous playback. Such a file is proper Ogg, but not "Ogg Vorbis I" -- the Ogg Vorbis I specification defines an Ogg Vorbis file as an Ogg file containing only one Vorbis track at a time (ie. no parallel multiplexing). Many music players (which use libvorbisfile) aren't designed to play multitrack Ogg files. In general however, video players, and anything built on a multimedia framework (like GStreamer, DirectShow etc.) will probably be able to handle such files. If you want to create a file containing some Ogg files sequenced one after another, then you should simply concatenate them together using cat. In Ogg this is called "chaining". If you cat Ogg Vorbis I audio files together, then the result will also be a compliant Ogg Vorbis file. Options oggz-merge accepts the following options: Miscellaneous options -o filename, --output filename Write output to the specified filename instead of printing it to standard output. -h, --help Display usage information and exit. -v, --version Output version information and exit. EXAMPLES
Merge pages of audio.oga and video.ogv: oggz merge -o output.ogv audio.oga video.ogv AUTHOR
