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
