It's my engineering background - swiss army knife versus scalpel. The '
zcat -d filename.gz | grep ^A > a-file ' worked and it also had the
benefit of sorting in alphabetical order. The file in question was not
in alphabetical order. The split solution is more elegant though.

Ah but when people give estimates of how many .com domains are
registered, I can laugh insanely, say that they are wrong and give the
right figure. :-) Actually it is part of the whoisireland.com project -
mapping domain ownership/nameservers/key words. I think that
domainwatch.com was doing something similar but they had to give up in
March as the format of the file changed. (I think it could have been a
switch from alphabetical order to non-alphabetical.) The main problem at
the moment is bandwidth. D/ling a 348 MB file each day is agony on ISDN.
