LPQ(1)                                                                  LPQ(1)



NAME
       lpq - spool queue examination program

SYNOPSIS
       lpq [ -a ] [ -A ] [ -l ] [ -L ] [ -P printer ] [ -s ]
            [ -t sleeptime ] [ -V ] [ -D debugopt ]
            [ jobid...  ]

DESCRIPTION
       lpq requests a status report from lpd(8) on the specified printers or
       jobs.  lpq invoked without any arguments reports on the printer given
       by the default printer (see -P option).  The short (default) format
       simply lists the printer, host, and numbers of jobs in the spool queue.
       When using the long format (-l option), for each job in a spool queue
       lpq reports the job identifier which is generated from the user's name
       and originating host, current rank in the queue, the job number (which
       may be supplied to lprm(1) for removing a specific job), the job
       description information, and the total size in bytes.  If there is an
       error or other problem with the job, this information may be modified
       to reflect the problems.  In a spool queue, Job ordering is a modified
       FIFO (First in First Out), modified by the job class and priority
       information.

       The following options are available.

       -A     Use authentication specified by the value of the AUTH
              environment variable.

       -Ddebugoptions
              Debugging is controlled using the -D option. This accepts a
              comma-separated list of debugging settings. These settings take
              one of two forms: facility=value , or value to set an overall
              default value.

       -P printer
              By default, the destination printer is taken from the command
              line printer value, then the environment variables PRINTER,
              LPDEST, NPRINTER, NGPRINTER, then first entry in the printcap
              information, and and finally the default_printer entry from the
              configuration file, and then the compile time default.

       -V     Print version information.

       -a     List status for all printers (see PRINTER LISTS below) which
              have entries for the LPRng client programs in the printcap(5)
              database.

       -l     Increase verbosity of the long display format.  A single -l
              options selects a short verbose display, multiple -l options
              increase the verbosity.

       -L     Use maximum verbosity for the long display format.

       -s     Display a short, single line status summary for each queue and
              subqueue.

       -tsleeptime
              Forces lpq to periodically display the spool queues and then
              sleep sleeptime seconds between scans of the queue.

       jobid ... all
              The options are followed by a list of jobids which are used to
              select jobs of interest.  A jobid can be a user name, a job
              identifier, a job number, or a glob based pattern which will be
              applied to the job identifiers.  The all keyword will display
              all jobs and is the default option.

       The lpq will report the status of the spool queue (enabled for
       spooling, disabled for unspooling), and the absence of a server if
       unspooling is enabled.  The lpc(1) command lpc start <printer> may be
       used to start the server if this is the case.

ENVIRONMENT
       By default, the destination printer is taken from the command line dest
       value, then the environment variables PRINTER, LPDEST, NPRINTER,
       NGPRINTER, then first entry in the printcap information, and and
       finally the default_printer entry from the configuration file, and then
       the compile time default.

PRINTER LISTS
       The -a option is used to by lpq(1) to get status for a list of
       printers.  This list is formed as follows.

       1)     The printcap file is scanned for printer entries.  Only entries
              with names starting with a letter or digit are recognized as
              valid queue or printer names.

       2)     If the special entry all is present, and it has a field
              :all=pr1@host1,pr2@host2,...  then the printers pr1, pr2, ...
              are used as the printer or queue list.

       3)     If there is no all entry, then the original list of printers
              found in step 1) is used as the list of printers.

       The special case of lpq -Pall disables the searching of the printcap
       database, and simply sends a query to the lpd server for status of
       printer all.  The lpd(8) server enumerates the printers in its printcap
       file, ignoring any all entry, and returns status only for printers
       which have entries in the lpd(8) server printcap file.

       Finally, the special case lpq -Ppr@host causes lpq(1) to send a status
       request for printer pr to host host.

       Here is a simple set of rules to use:
       Client:
        pr1:lp=%P@server
        pr2:lp=%P@server
         - printer pr1 followed by pr2

       pr1:lp=%P@server
       pr2:lp=%P@server
       all:all=pr2,pr1
         - printer pr2 followed by pr1 (all overrides)

       Client:
        pr1:lp=%P@server
        pr2:lp=%P@server
       Server:
        lp:lp=...
         lpq -Pall
           - status returned only for printer 'lp'

EXIT STATUS
       The following exit values are returned:

       zero (0)       Successful completion.

       non-zero (!=0) An error occurred.

PRINTCAP INFORMATION
       The printer names and other information is obtained by using a printcap
       file or some other database.  The ${HOME}/.printcap file can be used to
       specify user level options and configuration information.  See
       printcap(5) for more information.

FILES
       The files used by LPRng are set by values in the printer configuration
       file.  The following are a commonly used set of default values.
       /etc/LPRng/lpd.conf                          LPRng configuration file
       ${HOME}/.printcap                            user printer description file
       /etc/printcap                                printer description file
       /etc/LPRng/lpd.perms                         permissions
       /var/run/lpd                                 lock file for queue control
       /var/spool/lpd                               spool directories
       /var/spool/lpd/QUEUE/control                 queue control
       /var/spool/lpd/QUEUE/log                     trace or debug log file
       /var/spool/lpd/QUEUE/acct                    accounting file
       /var/spool/lpd/QUEUE/status                  status file

DIAGNOSTICS
       Most of the diagnostics are self explanatory.  If you are puzzled over
       the exact cause of failure, set the debugging level on (-D5) and run
       again.  The debugging information will help you to pinpoint the exact
       cause of failure.
