well reading the code would be a travesty. it's curious
that neither the sam paper nor regexp(6) mentions
submatches. maybe i missed them.
sed -n 's:.*(KRAK[A-Z]+*) +([a-zA-Z]+).*:\2, \1:gp' </lib/volcanoes
sam -d /lib/volcanoes
,x g/KRAK/ s:[^A-Z]+([A-Z]+*) +([a-zA-Z]+).*:\2, \1:
/KRAK/-+
or, if you want to run sam as a stream editor
{ echo ',x g/KRAK/ s:[^A-Z]+([A-Z]+*) +([a-zA-Z]+).*:\2, \1:'
echo '/KRAK/-+'
} | sam -d /lib/volcanoes >[2=]
a couple of examples of submatch tracking from our system
(i'm not sure about the version of iwhois on sources.)
