who@(1) General Commands Manual who@(1)


who@ - prints the list of active users on a remote host.


who@ [ host ]


who@ connects to TCP port 11 (Systat) on host and prints any data it receives. It removes CR (\015) 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 -RHl0 0 11 who

using tcpserver.
