checkpc - check out the printcap database
checkpc [ -aflprsCV ] [ -A age[DHMS] ] [ -D debugflags ] [ -P printer ] [ -t size[kM] ]
DESCRIPTION
Checkpc is used to check for the existence and correct permissions of entries in the printcap database. It is
useful when installing a new printcap database and cleaning up existing printer spoolers.
-a Do not create accounting files (:lf).
-f The fix flag will cause the checkpc program create and fix various files and permissions. It does this in a
simple minded manner, and the program may have to be run several times until all permissions are correct.
It also reports in extremely verbose details its actions.
-l Do not create log files (:lf).
-p Print verbose printcap information. Useful if interested in the printcap values.
-r remove junk or job files older than the age set by -A. You must set the age to a non-zero value otherwise
no files are removed.
-s Do not create filter status files (:ps).
-A Age[DHMS]
Report junk or job files older than age. The age time can have a suffix days (D) hours (H), minutes (M), or
seconds (S); default is days.
-D debugflags
Run the program with debugging flags. See the LPRng HOWTO for details of the flags actions.
-V Verbose mode.
-P printer
Process only the specified print queue.
-t size[kM]
Truncate log files (:lf) to the specified size in Kbytes or Mbytes (default is Mbytes).
ANNOYING FEATURES
If the -f (fix) option is specified and you do not run this as root, it will complain, but attempt to carry out
the operations. This will lead to a large number of failures reports if the ownership and/or permissions are
incorrect.
FILES
The files used by LPRng are set by values in the printer configuration file and by configuration options. The
following are a commonly used set of default values.
/etc/lpd.conf LPRng configuration file
${HOME}/.printcap user printer description file
/etc/printcap printer description file
/etc/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.
