I symlink the airport command into /usr/local/bin so that you can call it from any shell. The former will draw a very nice graph of signal and noise for you and can perform wireless scans, Bonjour service mapping (both locally and across the internet IPv4 and IPv6), ARP, and just about anything that the normal network utility tool does except for port scanning. /System/Library/PrivateFrameworks/amework/Versions/Current/Resources/airport.
