Using 'Finger' Command Now that 'finger' is installed, you can use it to display user information. Simply type finger followed by a username. This command will display information about the root user, including the login name, real name, and the time they last logged in.

The finger command displays a M- before each converted character. When you specify users with the User parameter, you can specify either the user's first name, last name, or account name. When you specify users, the finger command, at the specified host, returns information about those users only in long format.

The finger command may also be used to look up users on a remote system. The format is to specify the user as User@Host. If you omit the user name, the finger command provides the standard format listing on the remote system.

The 'finger' command in Linux is a user information lookup program. It provides details about users on a Linux system. You can use it like this: finger [username] . Here's a simple example: finger root # Output: # Login: root Name: root # Directory: /root Shell: /bin/bash # Never logged in.
