NAME

       clfsplit - split Common-Log Format web logs based on IP address

SYNOPSIS

       clfsplit [--help] [-i input] -d defaultfile -f file -s spec [-f file -s spec]

DESCRIPTION

       The  clfsplit  will  split  up large CLF format web logs based on IP address.  This is for
       creating separate log analysis passes for internal and external users of web pages.

OVERVIEW

       The defaultfile parameter specifies where data goes if it doesn't  match  any  of  the  IP
       ranges.  This could be /dev/null depending on your aims.

       The -i input parameter gives the file to take input from (default standard input).

       The -f file parameter must be given before the list of IP addresses.

       The spec parameter is the IP addresses that go to the file in question.  It is of the form
       start[-end][:start[-end]] where start and end specify the start and ends of ranges of IPs.
       Also  the CIDR notation can be used or a single IP address.  If there is a large number of
       IP ranges then a file name can be given which contains a set of IP ranges, one  range  per
       line.

EXIT STATUS

       0 No errors

       1 Bad parameters

       2 Can't open input

       3 Can't open/write to output file

       4 Can't open and read from spec file
