That will include the *** file delimiters in the output, which is not indicated by the sample data.

Nitpicks, but I'll point them out anyway. The regular expression will match any line that contains three consecutive asterisks and not just that sequence. Not knowing anything about the text in the file, it would be safer to anchor that regular expression on both ends.

If the file has many *** delimiters, the open file descriptor count could hit the user limit.


An alternative:
Code:
awk '$0=="***" || NR==1 {close(f); f=++n".dat"}  $0!="***" {print > f}' file

savemixer(8)						OSS System Administration Commands					      savemixer(8)

NAME

       savemixer - Open Sound System program for saving and restoring mixer settings.

SYNOPSIS

       savemixer [-LVv] [-f <fname>]

DESCRIPTION

       The savemixer program saves mixer settings. It can also load saved mixer settings back into the mixer.

       Running	this  program  without	any parameters will save the current mixer settings into /var/lib/oss4/mixer.save or $OSSVARDIR/mixer.save
       file.  OSSVARDIR is decided by reading /etc/oss.conf, and defaults to /var/lib/oss4.

AUTOMATIC SAVE

       By default the soundoff command will automatically run savemixer to save the active mixer settings. See the manual page for soundoff(1)	if
       you like to turn this feature off.

OPTIONS

       -f<fname>
	      Use <fname> as setting file.

       -L     Loads saved mixer and device map information from mixer.save.

       -V     Version information.

       -v     Verbose output.

SEE ALSO

       soundoff(1), soundon(1), ossdetect(1), ossdevlinks(1), ossmix(1), ossxmix(1)

FILES

       /etc/oss.conf /usr/sbin/savemixer /var/lib/oss4/mixer.save /var/lib/oss4/dspdevs.map /var/lib/oss4/applist.conf
