finger - display information about local and remote users  


finger [-bfhilmpqsw] [username...]

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

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


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

• user name

• user's full name

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

• idle time

• login time

• 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:

• the user name and the user's full name

• the user's home directory and login shell

• 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

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

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

• 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 [email protected]1[@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.  


The following options are supported, except that the [email protected] 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.

The finger user information protocol limits the options that may be used with the remote form of this command.
