請叫我awk小(nao)王(can)子(fen)

1 2 3 4 5 6 7 8 9 10 |
tail -f /var/log/nginx/access.log|awk '{ if ($9 >= 400) $9="\33[1;31m"$9"\33[0m"; else $9="\33[1;32m"$9"\33[0m"; $1="\33[1;35m"$1"\33[0m"; $7="\33[33m"$7"\33[0m"; $10="\33[1;36m"$10"\33[0m"; print $0; }' |
效果 
不想寫python，而且我比較相信awk+uniq+sort的速度

awk -v date="$(date '+\%d/\%b/\%Y')" '($4 ~ date && $9 ~ /200/ ){print $1,$7}' /var/log/nginx/access.log | sort | uniq |awk '{print $2}'|sort|uniq -c|sort -r|head -n 50 |

rm /etc/localtime cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime |
time計時
52M日誌，26w條

134M日誌，加上了兩個自定義條件，65w條
