checkpc − check out the printcap database
checkpc [ −aflprsV ] [ −Aage[DHMS] ] [ −Ddebugflags ] [ −Pprinter ] [ −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 (:af). |
||
−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).
−T serial-line
set process name and start feature test
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.

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.
