73hours and minutes, unless more than six months ago, in which case the year 74is displayed rather than the hours and minutes. 75.Pp 76Unknown devices as well as nonexistent idle and login times are 77displayed as single asterisks. 78.It Fl h 79When used in conjunction with the 80.Fl s 81option, the name of the remote host is displayed instead of the office 82location and office phone. 83.It Fl o 84When used in conjunction with the 85.Fl s 86option, the office location and office phone information is displayed 87instead of the name of the remote host. 88.It Fl g 89This option restricts the gecos output to only the users' real 90name. 91It also has the side-effect of restricting the output 92of the remote host when used in conjunction with the 93.Fl h 94option. 95.It Fl k 96Disable all use of the user accounting database. 97.It Fl l 98Produce a multi-line format displaying all of the information 99described for the 100.Fl s 101option as well as the user's home directory, home phone number, login 102shell, mail status, and the contents of the files 103.Pa .forward , 104.Pa .plan , 105.Pa .project 106and 107.Pa .pubkey 108from the user's home directory. 109.Pp 110If idle time is at least a minute and less than a day, it is 111presented in the form ``hh:mm''. 112Idle times greater than a day are presented as ``d day[s]hh:mm''. 113.Pp 114Phone numbers specified as eleven digits are printed as ``+N-NNN-NNN-NNNN''. 115Numbers specified as ten or seven digits are printed as the appropriate 116subset of that string. 117Numbers specified as five digits are printed as ``xN-NNNN''. 118Numbers specified as four digits are printed as ``xNNNN''. 119.Pp 120If write permission is denied to the device, the phrase ``(messages off)'' 121is appended to the line containing the device name. 122One entry per user is displayed with the 123.Fl l 124option; if a user is logged on multiple times, terminal information 125is repeated once per login. 126.Pp 127Mail status is shown as ``No Mail.'' if there is no mail at all, ``Mail 128last read DDD MMM ## HH:MM YYYY (TZ)'' if the person has looked at their 129mailbox since new mail arriving, or ``New mail received ...'', ``Unread 130since ...'' if they have new mail. 131.It Fl p 132Prevent 133the 134.Fl l 135option of 136.Nm 137from displaying the contents of the 138.Pa .forward , 139.Pa .plan , 140.Pa .project 141and 142.Pa .pubkey 143files. 144.It Fl m 145Prevent matching of 146.Ar user 147names. 148.Ar User 149is usually a login name; however, matching will also be done on the 150users' real names, unless the 151.Fl m 152option is supplied. 153All name matching performed by 154.Nm 155is case insensitive. 156.El 157.Pp 158If no options are specified, 159.Nm 160defaults to the 161.Fl l 162style output if operands are provided, otherwise to the 163.Fl s 164style. 165Note that some fields may be missing, in either format, if information 166is not available for them. 167.Pp 168If no arguments are specified, 169.Nm 170will print an entry for each user currently logged into the system. 171.Pp 172The 173.Nm 174utility may be used to look up users on a remote machine. 175The format is to specify a 176.Ar user 177as 178.Dq Li user@host , 179or 180.Dq Li @host , 181where the default output 182format for the former is the 183.Fl l 184style, and the default output format for the latter is the 185.Fl s 186style. 187The 188.Fl l 189option is the only option that may be passed to a remote machine. 190.Pp 191If the file 192.Pa .nofinger 193exists in the user's home directory, 194and the program is not run with superuser privileges, 195.Nm 196behaves as if the user in question does not exist. 197.Pp 198The optional 199.Xr finger.conf 5 200configuration file can be used to specify aliases. 201Since 202.Nm 203is invoked by 204.Xr fingerd 8 , 205aliases will work for both local and network queries. 206.Sh ENVIRONMENT 207The 208.Nm 209utility utilizes the following environment variable, if it exists: 210.Bl -tag -width Fl 211.It Ev FINGER 212This variable may be set with favored options to 213.Nm . 214.El 215.Sh FILES 216.Bl -tag -width /var/log/utx.lastlogin -compact 217.It Pa /etc/finger.conf 218alias definition data base 219.It Pa /var/log/utx.lastlogin 220last login data base 221.El 222.Sh SEE ALSO 223.Xr chpass 1 , 224.Xr w 1 , 225.Xr who 1 , 226.Xr finger.conf 5 , 227.Xr fingerd 8 228.Rs 229.%A D.
