Hai!
whois.conf-compatible format
What uses whois.conf? Not the whois on my FreeBSD or Mac.
Or you can just use this shell script:
#!/bin/bash
WHOISHOST=${1##*.}.ws.sp.am
exec whois -h $WHOISHOST $*
I just a slightly different one but still my fav one... jwhois Has a whois.conf style list. Bye, Raymond.
