Sort uniq IP address in from Apache log

Question

I\'m trying to extract IP addresses from my apache log, count them, and sort them.

And for whatever reason, the sorting part is horrible.

Here is the command

Answer 1

This should work

cat access.* | awk '{ print $1 }' | sort | awk '{print $1 " " $2;}' | sort -n

I can't see a problem.

Control characters in the files?

File system full (temp files)?
