Suggest some minor changes: - Use "$9 ~ /" 404 [-0-9]/ -- if any part of the line has "404" like the referer or user agent, it will be included - Use $1 instead of $2. $2 is the remote name if supplied. I have never seen it supplied. Use the IP address/hostname from field 1 instead. - Combine both awk one-liners into one awk '$9 ~ /" 404 [-0-9]/ { print $1, $9, $7, $11 }' | sort | uniq -c
