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.
