If I grep one of my logfiles for a certain error message I get all the lines that contain that error. However, I'd like to sort those lines by another search criterium such as IP address involved in the error. I'm suspecting there's a very common tool that can do that for me but I have no idea which one.
Perhaps my english is the problem here. Let me clarify.
As you can see the IP 211.245.142.178 is registered twice in this snippet. Quite possibly it's also present elsewhere in the log.
What I would like to is grep for a 404 and filter the output somehow so that I get all the same ip adresses next to eachother so that ?I can see exactly what 211.245.142.178 has been upto.
