who@ - displays who is on the system
who@ [ host ] ]
who@ connects via IP[v4|v6] to TCP port 11 (Systat) on host and prints
any data it receives. It removes CR and converts unprintable
characters to a visible format.
If host is not supplied, who@ connects to the local host.
Some computers respond to port 11 with a list of active users. For
example, they may be running
tcpserver -4 0 11 who &
cat(1), delcr(1), tcpclient(1), tcpserver(1)
