If 58.Fl h 59is given, the remote host is printed (the default.) If 60.Fl o 61is given, the office location and office phone number is printed 62instead. 63.Pp 64Idle time is in minutes if it is a single integer, hours and minutes 65if a ``:'' is present, or days if a ``d'' is present. 66Login time is displayed as the dayname if less than 6 days, else month, day; 67hours and minutes, unless more than six months ago, in which case the year 68is displayed rather than the hours and minutes. 69.Pp 70Unknown devices as well as nonexistent idle and login times are 71displayed as single asterisks. 72.Pp 73.It Fl h 74When used in conjunction with the 75.Fl s 76option, the name of the remote host is displayed instead of the office 77location and office phone. 78.Pp 79.It Fl o 80When used in conjunction with the 81.Fl s 82option, the office location and office phone information is displayed 83instead of the name of the remote host. 84.Pp 85.It Fl l 86Produces a multi-line format displaying all of the information 87described for the 88.Fl s 89option as well as the user's home directory, home phone number, login 90shell, mail status, and the contents of the files 91.Dq Pa .forward , 92.Dq Pa .plan 93and 94.Dq Pa .project 95from the user's home directory. 96.Pp 97If idle time is at least a minute and less than a day, it is 98presented in the form ``hh:mm''. 99Idle times greater than a day are presented as ``d day[s]hh:mm''. 100.Pp 101Phone numbers specified as eleven digits are printed as ``+N-NNN-NNN-NNNN''. 102Numbers specified as ten or seven digits are printed as the appropriate 103subset of that string. 104Numbers specified as five digits are printed as ``xN-NNNN''. 105Numbers specified as four digits are printed as ``xNNNN''. 106.Pp 107If write permission is denied to the device, the phrase ``(messages off)'' 108is appended to the line containing the device name. 109One entry per user is displayed with the 110.Fl l 111option; if a user is logged on multiple times, terminal information 112is repeated once per login. 113.Pp 114Mail status is shown as ``No Mail.'' if there is no mail at all, ``Mail 115last read DDD MMM ## HH:MM YYYY (TZ)'' if the person has looked at their 116mailbox since new mail arriving, or ``New mail received ...'', ``Unread 117since ...'' if they have new mail. 118.Pp 119.It Fl p 120Prevents 121the 122.Fl l 123option of 124.Nm finger 125from displaying the contents of the 126.Dq Pa .forward , 127.Dq Pa .plan 128and 129.Dq Pa .project 130files. 131.It Fl m 132Prevent matching of 133.Ar user 134names. 135.Ar User 136is usually a login name; however, matching will also be done on the 137users' real names, unless the 138.Fl m 139option is supplied. 140All name matching performed by 141.Nm finger 142is case insensitive. 143.Pp 144.It Fl T 145Disable the use of T/TCP (see 146.Xr ttcp 4 ). 147This option is needed to finger hosts with a broken TCP implementation. 148.El 149.Pp 150If no options are specified, 151.Nm finger 152defaults to the 153.Fl l 154style output if operands are provided, otherwise to the 155.Fl s 156style. 157Note that some fields may be missing, in either format, if information 158is not available for them. 159.Pp 160If no arguments are specified, 161.Nm finger 162will print an entry for each user currently logged into the system. 163.Pp 164.Nm Finger 165may be used to look up users on a remote machine. 166The format is to specify a 167.Ar user 168as 169.Dq Li user@host , 170or 171.Dq Li @host , 172where the default output 173format for the former is the 174.Fl l 175style, and the default output format for the latter is the 176.Fl s 177style. 178The 179.Fl l 180option is the only option that may be passed to a remote machine. 181.Pp 182If the file 183.Dq Pa .nofinger 184exists in the user's home directory, 185.Nm finger 186behaves as if the user in question does not exist. 187.Sh ENVIRONMENT 188.Nm Finger 189utilizes the following environment variable, if it exists: 190.Bl -tag -width Fl 191.It Ev FINGER 192This variable may be set with favored options to 193.Nm finger . 194.El 195.Sh FILES 196.Bl -tag -width /var/log/lastlog -compact 197.It Pa /var/log/lastlog 198last login data base 199.El 200.Sh SEE ALSO 201.Xr chpass 1 , 202.Xr w 1 , 203.Xr who 1 , 204.Xr ttcp 4 . 205.Sh HISTORY 206The 207.Nm finger 208command appeared in 209.Bx 3.0 . 210
