Need to remove lines that start with an IP address
Hi,

I keep having to remove lines have an IP address as the second field from my awstats logs, as it makes the processing fail.

Rather than do it individually each time (once or twice a week) it fails, I'd like to remove any lines from the file that have 3 digits and then a dot as the start of the second field as they are sure to be an IP.

The field separators are spaces

I know if the line starts with an IP I can easily do it with grep like so:

Code:
 grep -v '\^[0-9][0-9][0-9]' file > tempfile; mv tempfile file

But this is the second field so I imagine I have to use awk, right?

Any ideas would be appreciated

LEARN ABOUT DEBIAN

deb-origin

deb-origin(5)							      Debian							     deb-origin(5)

NAME

       deb-origin - Vendor-specific information files

SYNOPSIS

       /etc/dpkg/origins/filename

DESCRIPTION

       The  files  in  /etc/dpkg/origins can provide information about various vendors who are providing Debian packages. They contain a number of
       fields, or comments when the line starts with '#'.  Each field begins with a tag, such as Vendor or Parent, followed by	a  colon  and  the
       body  of the field. Fields are delimited only by field tags. In other words, field text may be multiple lines in length, but the tools will
       join lines when processing the body of the field.

REQUIRED FIELDS

       Vendor: vendor-name
	      The value of this field determines the vendor name.

OPTIONAL FIELDS

       Vendor-URL: vendor-url
	      The value of this field determines the vendor URL.

       Bugs: bug-url
	      The value of this field determines the type and address of the bug tracking system used by this vendor. It can be a mailto URL or  a
	      debbugs URL (e.g., debbugs://bugs.debian.org/).

       Parent: vendor-name
	      The value of this field determines the vendor name of the vendor that this vendor derives from.

EXAMPLE

       Vendor: Debian
       Vendor-URL: http://www.debian.org/
       Bugs: debbugs://bugs.debian.org
