finger@ - gets user information from a remote host.
finger@ [ host [ user ] ]
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.
