A finger is a network protocol used to obtain information about a particular user on a remote system. The most common use for finger is to determine whether a particular user is logged into the system. The finger protocol is defined in RFC 1288.

The finger protocol works by connecting to the finger port ( typically port 79 ) on a remote system and sending a query in the form of user@host. The remote system then responds with the requested information, which can include the user's full name, email address, and last login time.

Some systems also allow finger queries to be directed at specific services, such as email or web servers, in order to obtain information about the status of those services. For example, a finger query to an email server might return the number of unread messages in a user's inbox. What is finger slang?
