finger@ - get user information from a host

finger@  connects  to TCP port 79 (Finger) on host, sends user (with an extra CR) to host, and prints any
       data it receives.  It removes CR and converts unprintable characters to a visible format.  Some computers
       respond to port 79 with information about user.

       If user is not supplied, finger@ sends a blank line to host.  Some  computers  respond  with  information
       about all the users who are logged in.

       If host is not supplied, finger@ connects to the local host.
