checkpc − check out the /etc/printcap database
checkpc [ −aflprsCV ] [ −A age[DHMS] ] [ −D debugflags ] [ −P printer ] [ −t size[kM] ]
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). | ||
|
−c |
Print verbose configuration information. | ||
|
−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).
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.
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
or /usr/local/etc/lpd.conf
|
/etc/printcap |
printer description file |
or /usr/local/etc/printcap
|
/etc/lpd.perms |
printer permissions |
or /usr/local/etc/lpd.perms
|
/var/spool/lpd |
spool directories | |
|
/var/spool/lpd/queue/lock |
lock file for queue control | |
|
/var/spool/lpd/queue/control |

|
/var/spool/lpd/queue/log |

|
/var/spool/lpd/queue/acct |

lpd.conf(5), lpc(8), lpd(8), lpr(1), lpq(1), lprm(1), printcap(5), lpd.perms(5), pr(1).
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.
