clfsplit(1)                        logtools                        clfsplit(1)


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
