75hours and minutes, unless more than six months ago, in which case the year 76is displayed rather than the hours and minutes. 77.Pp 78Unknown devices as well as nonexistent idle and login times are 79displayed as single asterisks. 80.It Fl h 81When used in conjunction with the 82.Fl s 83option, the name of the remote host is displayed instead of the office 84location and office phone. 85.It Fl o 86When used in conjunction with the 87.Fl s 88option, the office location and office phone information is displayed 89instead of the name of the remote host. 90.It Fl g 91This option restricts the gecos output to only the users' real 92name. 93It also has the side-effect of restricting the output 94of the remote host when used in conjunction with the 95.Fl h 96option. 97.It Fl k 98Disable all use of the user accounting database. 99.It Fl l 100Produce a multi-line format displaying all of the information 101described for the 102.Fl s 103option as well as the user's home directory, home phone number, login 104shell, mail status, and the contents of the files 105.Pa .forward , 106.Pa .plan , 107.Pa .project 108and 109.Pa .pubkey 110from the user's home directory. 111.Pp 112If idle time is at least a minute and less than a day, it is 113presented in the form ``hh:mm''. 114Idle times greater than a day are presented as ``d day[s]hh:mm''. 115.Pp 116Phone numbers specified as eleven digits are printed as ``+N-NNN-NNN-NNNN''. 117Numbers specified as ten or seven digits are printed as the appropriate 118subset of that string. 119Numbers specified as five digits are printed as ``xN-NNNN''. 120Numbers specified as four digits are printed as ``xNNNN''. 121.Pp 122If write permission is denied to the device, the phrase ``(messages off)'' 123is appended to the line containing the device name. 124One entry per user is displayed with the 125.Fl l 126option; if a user is logged on multiple times, terminal information 127is repeated once per login. 128.Pp 129Mail status is shown as ``No Mail.'' if there is no mail at all, ``Mail 130last read DDD MMM ## HH:MM YYYY (TZ)'' if the person has looked at their 131mailbox since new mail arriving, or ``New mail received ...'', ``Unread 132since ...'' if they have new mail. 133.It Fl p 134Prevent 135the 136.Fl l 137option of 138.Nm 139from displaying the contents of the 140.Pa .forward , 141.Pa .plan , 142.Pa .project 143and 144.Pa .pubkey 145files. 146.It Fl m 147Prevent matching of 148.Ar user 149names. 150.Ar User 151is usually a login name; however, matching will also be done on the 152users' real names, unless the 153.Fl m 154option is supplied. 155All name matching performed by 156.Nm 157is case insensitive. 158.El 159.Pp 160If no options are specified, 161.Nm 162defaults to the 163.Fl l 164style output if operands are provided, otherwise to the 165.Fl s 166style. 167Note that some fields may be missing, in either format, if information 168is not available for them. 169.Pp 170If no arguments are specified, 171.Nm 172will print an entry for each user currently logged into the system. 173.Pp 174The 175.Nm 176utility may be used to look up users on a remote machine. 177The format is to specify a 178.Ar user 179as 180.Dq Li user@host , 181or 182.Dq Li @host , 183where the default output 184format for the former is the 185.Fl l 186style, and the default output format for the latter is the 187.Fl s 188style. 189The 190.Fl l 191option is the only option that may be passed to a remote machine. 192.Pp 193If the file 194.Pa .nofinger 195exists in the user's home directory, 196and the program is not run with superuser privileges, 197.Nm 198behaves as if the user in question does not exist. 199.Pp 200The optional 201.Xr finger.conf 5 202configuration file can be used to specify aliases. 203Since 204.Nm 205is invoked by 206.Xr fingerd 8 , 207aliases will work for both local and network queries. 208.Sh ENVIRONMENT 209The 210.Nm 211utility utilizes the following environment variable, if it exists: 212.Bl -tag -width Fl 213.It Ev FINGER 214This variable may be set with favored options to 215.Nm . 216.El 217.Sh FILES 218.Bl -tag -width /var/log/utx.lastlogin -compact 219.It Pa /etc/finger.conf 220alias definition data base 221.It Pa /var/log/utx.lastlogin 222last login data base 223.El 224.Sh SEE ALSO 225.Xr chpass 1 , 226.Xr w 1 , 227.Xr who 1 , 228.Xr finger.conf 5 , 229.Xr fingerd 8 230.Rs 231.%A D.
