Getting lines before and until next pattern in file /awk, sed
Hi,

I need to get specific parts in a large file.

I need to:
Get a line containing an IP address, and read from there to another line saying ***SNMP-END***

So, I have the start and the end well defined, but the problem is that apparently the awk command using the -F option doesn't work good with the IP address, let's say 1.1.1.1

Originally the text it will be like this:

Code:
***SNMP-ST***
IP = 1.1.1.1
some text here
***SNMP-END***

That's what I have been trying to do, btw .. the file contains thousands of IP addresses and some of these 1.1.1.1, which are the ones I need to capture.

Any help is greatly appreciated.

NAME

       SNMP::Info::Layer2::Airespace - SNMP Interface to Cisco (Airespace) Wireless Controllers

AUTHOR

       Eric Miller

SYNOPSIS

	   #Let SNMP::Info determine the correct subclass for you.

	   my $airespace = new SNMP::Info(
				 AutoSpecify => 1,
				 Debug	     => 1,
				 DestHost    => 'myswitch',
				 Community   => 'public',
				 Version     => 2
			       )

	   or die "Can't connect to DestHost.
";

	   my $class = $airespace->class();
	   print " Using device sub class : $class
";

DESCRIPTION

       Provides abstraction to the configuration information obtainable from Cisco (Airespace) Wireless Controllers through SNMP.

       For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

       my $airespace = new SNMP::Info::Layer2::Airespace(...);
