All other arguments supplied are interpreted as user 69names or job numbers to filter out only those jobs of interest. 70.It Fl l 71Information about each of the files comprising the job entry 72is printed. 73Normally, only as much information as will fit on one line is displayed. 74.It Fl a 75Report on the local queues for all printers, 76rather than just the specified printer. 77.El 78.Pp 79For each job submitted (i.e. invocation of 80.Xr lpr 1 ) 81.Nm 82reports the user's name, current rank in the queue, the 83names of files comprising the job, the job identifier (a number which 84may be supplied to 85.Xr lprm 1 86for removing a specific job), and the total size in bytes. 87Job ordering is dependent on 88the algorithm used to scan the spooling directory and is supposed 89to be 90.Tn FIFO 91(First in First Out). 92File names comprising a job may be unavailable 93(when 94.Xr lpr 1 95is used as a sink in a pipeline) in which case the file 96is indicated as ``(standard input)''. 97.Pp 98If 99.Nm 100warns that there is no daemon present (i.e. due to some malfunction), 101the 102.Xr lpc 8 103command can be used to restart the printer daemon. 104.Sh ENVIRONMENT 105If the following environment variable exists, it is used by 106.Nm : 107.Bl -tag -width PRINTER 108.It Ev PRINTER 109Specifies an alternate default printer. 110.El 111.Sh FILES 112.Bl -tag -width "/var/spool/*/lock" -compact 113.It Pa /etc/printcap 114To determine printer characteristics. 115.It Pa /var/spool/* 116The spooling directory, as determined from printcap. 117.It Pa /var/spool/*/cf* 118Control files specifying jobs. 119.It Pa /var/spool/*/lock 120The lock file to obtain the currently active job. 121.El 122.Sh DIAGNOSTICS 123Unable to open various files.
