finger@ − get user information from a host
finger@ [ -version [ host [ user ] ] ]
finger@ connects via IP protocol -version (’-4’, ’-6’) 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 -version is not supplied, finger@ uses by default IPv6.
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.
