FINGER(1) User Commands FINGER(1)

NAME

finger - display information about local and remote users

SYNOPSIS

finger [-bfhilmpqsw] [username]...


finger [-l]
[username@hostname 1 [@hostname 2 .. .@hostname n]...]


finger [-l] [@hostname 1 [@hostname 2 .. .@hostname n]...]

DESCRIPTION

By default, the finger command displays in multi-column format the
following information about each logged-in user:

o user name

o user's full name

o terminal name (prepended with a `*' (asterisk) if write-
permission is denied)

o idle time

o login time

o host name, if logged in remotely


Idle time is in minutes if it is a single integer, in hours and
minutes if a `:' (colon) is present, or in days and hours if a `d'
is present.


When one or more username arguments are given, more detailed
information is given for each username specified, whether they are
logged in or not. username must be that of a local user, and may be
a first or last name, or an account name. Information is presented in
multi-line format as follows:

o the user name and the user's full name

o the user's home directory and login shell

o time the user logged in if currently logged in, or the
time the user last logged in; and the terminal or host
from which the user logged in

o last time the user received mail, and the last time the
user read mail

o the first line of the $HOME/.project file, if it exists

o the contents of the $HOME/.plan file, if it exists


Note: when the comment (GECOS) field in /etc/passwd includes a comma,
finger does not display the information following the comma.


If the arguments username@hostname1[@hostname2...@hostnamen] or
@hostname1[@hostname2...@hostnamen] are used, the request is sent
first to hostnamen and forwarded through each hostnamen-1 to
hostname1. The program uses the finger user information protocol (see
RFC 1288) to query that remote host for information about the named
user (if username is specified), or about each logged-in user. The
information displayed is server dependent.


As required by RFC 1288, finger passes only printable, 7-bit ASCII
data. This behavior may be modified by a system administrator by
using the PASS option in /etc/default/finger. Specifying PASS=low
allows all characters less than decimal 32 ASCII. Specifying
PASS=high allows all characters greater than decimal 126 ASCII.
PASS=low,high or PASS=high,low allows both characters less than 32
and greater than 126 to pass through.

OPTIONS

The following options are supported, except that the
username@hostname form supports only the -l option:

-b
Suppresses printing the user's home directory and shell in a
long format printout.


-f
Suppresses printing the header that is normally printed in a
non-long format printout.


-h
Suppresses printing of the .project file in a long format
printout.


-i
Forces "idle" output format, which is similar to short format
except that only the login name, terminal, login time, and
idle time are printed.


-l
Forces long output format.


-m
Matches arguments only on user name (not first or last name).


-p
Suppresses printing of the .plan file in a long format
printout.


-q
Forces quick output format, which is similar to short format
except that only the login name, terminal, and login time are
printed.


-s
Forces short output format.


-w
Suppresses printing the full name in a short format printout.
