Code:
awk '/^ST/{++i}{print > "file" i}' textfile

Code:
/^ST/{++i}

If the line begins with ST increase the variable i. The first time the name of the output file is file1, the next time the line begins with ST the name of the output file becomes file2 and so forth.

Code:
{print > "file" i}

Print the line to the file "file"i.

NAME

       ogmdemux - Extract streams from OGG/OGM files into separate files

SYNOPSIS

       ogmdemux [options] inname

DESCRIPTION

       This program extracts all or only some streams from an OGM and writes them to separate files.

       inname Use 'inname' as the source.

       -o, --output out
	      Use  'out'  as  the  base  for  destination  file  names.  '-v1', '-v2', '-a1', '-t1'... will be appended to this name. Default: use
	      'inname'.

       -a, --astream n
	      Extract specified audio stream. Can be used more than once. Default: extract all streams.

       -d, --vstream n
	      Extract specified video stream. Can be used more than once. Default: extract all streams.

       -t, --tstream n
	      Extract specified text stream. Can be used more than once. Default: extract all streams.

       -na, --noaudio
	      Don't extract any audio streams.

       -nv, --novideo
	      Don't extract any video streams.

       -nt, --notext
	      Don't extract any text streams.  Default: extract all streams.

       -r, --raw
	      Extract the raw streams only.  Default: extract to useful formats (AVI, WAV, OGG, SRT...).

       -v, --verbose
	      Increase verbosity.

       -h, --help
	      Show this help.

       -V, --version
	      Show version number.

NOTES

       What works:

       *      Extraction of the following formats is fully supported including writing the stream contents to useful container formats:
		video  -> AVI
		Vorbis -> OGG/Vorbis
		PCM    -> WAV
		text   -> text files (SRT subtitle format)

       *      All other audio streams (MP3, AC3) are just copied 1:1 into output files. MP3 and AC3 files should be usable. Others might not.

       What not works:

       *      Headers created by older OggDS (DirectShow) filter versions are not supported (and probably never will be).
