By default, information for each user on the host is listed. This informa-
tion includes the login name, terminal name and write status (an * (aster-
isk)) before the terminal name appears (if write permission is denied), and
The finger command uses a longer output format when you specify a user or a
list of users. You can use account name, given name, or surname (as listed
in /etc/passwd) to specify users. This multiline format includes the
information described previously, as well as full name, office number, and
phone number (if known); the user's home directory and login shell; idle
time; any plan that the user has placed in the file .plan in the user's
home directory; and the project on which the user is working from the file
.project in the home directory. (Idle time is minutes if it is a single
integer, hours and minutes if a : (colon) is present, or days and hours if
a d is present.)
If a host is not specified, the information is for users on the local host;
otherwise, the information is for users at the specified host. You can
specify a user on a remote host by using the form user@host; if you specify
@host alone, the standard format listing is provided on the remote system.
If a long format printout is to be produced, the -l option is passed to the
remote finger daemon. No other options are honored for remote finger
The finger command displays user information only if the specified host has
a fingerd server running or inetd is configured to start fingerd. If
fingerd is not running, the command returns a "Connection refused" error
message. (For more information on setting up this server for your host,
see the fingerd(8) daemon reference page.)
If you want to make information available to other users who run finger on
your user ID, you can create the following files in your home directory:
A file that contains plans. The .plan file can contain more than one
line. Set the protection on this file to 644.
A file that states what project you are currently working on. The
.project file can contain only one line. Set the protection on this
file to 644.
Set the protection on your home directory to 755 in order for the
world to access it. Keep in mind that all other files in your home
directory will also be accessible.
The f command is a supported alias for the finger command.
