Apache服务器使用bash记录最高流量

Question

I have an Apache server log and am trying to determine what IP address has generated the most traffic. I've already managed to get it formatted so its just the IPs and their traffic in bytes:

xxx.xxx.xxx.xxx 915925
yyy.yyy.yyy.yyy 1193
zzz.zzz.zzz.zzz 2356

So now I'm looking for a method to combine and add the bytes of identical IPs and then just find the top value.

Any ideas?

如果文件中有ip和traffic字节，请使用以下内容完成工作。

1. cat file | perl -ane '$h{ $F[0] } += $F[1]; END { for ( sort keys %h ) { printf qq[%s %d\\n], $_, $h{ $_ } } }' | sort -k2 -n -r

2. awk '{A[$1]+=$2;next}END{for(i in A){print i,A[i]}}' file | sort -k2 -n -r
