NAME
       wcmgr - Webalizer (DNS) Cache file Manager

SYNOPSIS
       wcmgr [ option ... ] cache-file

DESCRIPTION
       wcmgr  is  a  utility  program which allows manipulation of the DNS cache files used and produced by The Webalizer.  Each
       record in the cache file contains an IP address (either IPv4 or IPv6), a timestamp of when the entry  was  added  to  the
       cache,  a  flag  to  indicate if the record contains a resolved name or not, and either the same IP address or a resolved
       host name.  All records are accessed by their IP address.

RUNNING WCMGR
       wcmgr was designed to be run from the Unix shell command line.  This facilitates its use in shell scripts and other auto-
       mated  processes.   A  valid DNS cache file must be specified.  Command line options are optional, and if none are given,
       the default action is to list the contents of the specified cache file.

COMMAND LINE OPTIONS
       Different functions are selected by using one or more of the following command line options.  If no  options  are  given,
       the default is to display the contents of the cache file to the screen (stdout).

       -h      Display all available command line options and exit.

       -v      Be verbose.


       -V      Display  the program version and exit.  Additional program specific information will be displayed if verbose mode
               is also used (e.g. '-vV'), which can be useful when submitting bug reports.

       -a address [-n hostname] [-t0]
               Add a new record to the cache file.  The IP address will be added to the cache file using the current time as the
               timestamp  and  with a resolved name hostname.  If -t0 is specified, the record will be considered permanent, and
               will not be removed (during a purge) or expired.  If a hostname is not specified with the  -n  option,  then  the
               address will be used instead, and the record will be flagged as unresolved.

       -c      Create  a  new  cache  file.   If  used alone, this option will create a new, empty cache file.  If used with the
               import option, a new cache file will be created before importing the data.  An  error  will  occur  if  the  file
               cache-file already exists.

       -d address
               Delete a record from the cache file using the specified address.

       -f address
               Find  and  display information for address from the cache file.  A single line similar to that produced by the -l
               option will be displayed unless verbose mode is enabled, in which case a more detailed listing will be produced.

       -i name [-c]
               Import data into the cache file from the file name.  The import file must be a valid  tab  delimited  text  file,
               such  as  that  created by the export option.  If the imported data contains records already present in the cache
               file, those records will be overwritten by the imported data.  The cache file must exist unless the -c option  is
               specified, in which case, a new cache file will be created for the imported data.

       -l      List  the contents of the cache file.  This is the default action of the program, so does not necessarily need to
               be specified.  If verbose mode is enabled, a report title, column headers and summary totals will  also  be  dis-
               played.

       -p num  Purge  the  cache file of entries older than num days.  If num is not specified, then a default of 7 days will be
               used.  if verbose mode is enabled, each purged record will be printed and the total number of purged records will
               be displayed.

       -s [-t num]
               Display cache file information/statistics.  If a TTL value (in days) is specified using the -t option, it will be
               used to calculate how many records are older than num days, otherwise, the default value of 7 days will be used.

       -n name Specify the name to use as the resolved hostname when adding records to the cache.

       -t num  Time to live (TTL) value.  If used along with the -p (purge) option, it specifies how many  days  a  record  will
               remain valid.  Any record that is older than num days is considered expired and will be purged.  If used with the
               -a (add) option, a zero value will cause the record to be considered permanent.

       -x name Export data from a cache file to a tab delimited text file named name.  If the text file name exists, it will  be
               overwritten.
