Thank you all for replying and I apologize for not making myself clear when asking this question. I think
RudiC may have got it the closest, but I'm still not sure it's exactly what I'm looking for.
So, in my very large file, I have 6 fields and 300,000 lines of the same type of fields, obviously each line will contain different information in each field. But some lines will contain the same value in certain fields.
Here's my original qusetion:
"How would I find out how many times ip1 field shows up a particular file? Then how would I find out how many time ip1 and port 2 shows up?"
To explain this better: ip1 is not a header, but simply represents an IP address in field 2. Port2 simply represents a port number in field 5, associated with IP address in field 4. My goal is find out how many similar instances in field 2(ip1), shows up in this one file. THEN, I want to know how many times that same IP address shows up with the SAME port number (lets just say field 5).
I know awk could probably do this. But I was wondering if sort or uniq can recognize field values, as awk would recognize the field ip1, as $2.
I hope that clears it up. Thanks again...
