It was Xu's word "efficiently" that put me off replying earlier:
- efficient in reducing cpu processor time ? Or run time ? 
- efficient in minimising transient max disc used ? Or
- efficient in human time ? 
   not searching new tools or reading manuals if for a one off job
   & a solution already known, even if cludgy ?

I'd cludge it with my 
	http://berklix.com/~jhs/src/bsd/jhs/bin/public/mailsplit/
& if the mbox was truly monstrous & I was about to run out of space, either:
- first dd toward the end of mega mbox.
- or periodically delete numerous output files, either:
  - by suspending job 
  - or using another xterm in same dir.

There'll be other more efficient solutions  ;-)

Cheers,
