FINGER(1) BSD General Commands Manual FINGER(1)
finger -- user information lookup program
finger [-8ghlmops] [user ...] [user@host ...]
The finger displays information about the system users.
-8 Pass through 8-bit data. This option is intended for enabling 8-bit data output in the fingerd(8) service. Using this from the com-
mand line is dangerous, as the output data may include control characters for your terminal.
-g This option restricts the gecos output to only the users' real names.
-h When used in conjunction with the -s option, the name of the remote host is displayed instead of the office location and office phone.
-l Produces a multi-line format displaying all of the information described for the -s option as well as the user's home directory, home
phone number, login shell, mail status, and the contents of the files ``.forward'', ``.plan'' and ``.project'' from the user's home
If idle time is at least a minute and less than a day, it is presented in the form ``hh:mm''. Idle times greater than a day are pre-
sented as ``d day[s]hh:mm''.
Phone numbers specified as eleven digits are printed as ``+N-NNN-NNN-NNNN''. Numbers specified as ten or seven digits are printed as
the appropriate subset of that string. Numbers specified as five digits are printed as ``xN-NNNN''. Numbers specified as four digits
are printed as ``xNNNN''.
If write permission is denied to the device, the phrase ``(messages off)'' is appended to the line containing the device name. One
entry per user is displayed with the -l option; if a user is logged on multiple times, terminal information is repeated once per login.
Mail status is shown as ``No Mail.'' if there is no mail at all, ``Mail last read DDD MMM ## HH:MM YYYY (TZ)'' if the person has looked
at their mailbox since new mail arriving, or ``New mail received ...'', ``Unread since ...'' if they have new mail.
-m Prevent matching of user names. User is usually a login name; however, matching will also be done on the users' real names, unless the
-m option is supplied. All name matching performed by finger is case insensitive.
-o When used in conjunction with the -s option, the office location and office phone information is displayed instead of the name of the
-p Prevents the -l option of finger from displaying the contents of the ``.forward'', ``.plan'' and ``.project'' files.
-s finger displays the user's login name, real name, terminal name and write status (as a ``*'' after the terminal name if write permis-
sion is denied), idle time, login time, and either office location and office phone number, or the remote host. If -h is given, the
remote is printed. If -o is given, the office location and phone number is printed instead (the default).
Idle time is in minutes if it is a single integer, hours and minutes if a ``:'' is present, or days if a ``d'' is present. Login time
is displayed as the dayname if less than six days, else month, day, hours and minutes, unless more than six months ago, in which case
the year is displayed rather than the hours and minutes.
Unknown devices as well as nonexistent idle and login times are displayed as single asterisks.
If no options are specified, finger defaults to the -l style output if operands are provided, otherwise to the -s style. Note that some
fields may be missing, in either format, if information is not available for them.
If no arguments are specified, finger will print an entry for each user currently logged into the system.
finger may be used to look up users on a remote machine. The format is to specify a user as ``user@host'', or ``@host'', where the default
output format for the former is the -l style, and the default output format for the latter is the -s style. The -l option is the only option
that may be passed to a remote machine.
/var/log/lastlog last login data base
chpass(1), w(1), who(1)
