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  automated  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 displayed.

       -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.
