1.1.1 获取日志的最大top10,排序
获取两列到新的文件中第一次处理
sed截取字符串中间的内容,sed不支持贪婪匹配.找出图片在的列和图片大小到test1文件
本题需要输出三个指标：【访问次数】【访问次数*单个文件大小】【文件名（可以带URL）】

============================答题步骤
s sed截取字符串中间的内容,sed不支持贪婪匹配.找出图片在的列和图片大小到test1文件
sed -rn 's/.*GET (.*) HTTP.*200 (.*) /1 2/gp' bb.txt >>test1.txt
/static/images/photos/2.jpg 11299

/?= 46232 "-" "-"
/static/js/web_js.js 4460 "-" "-"
/static/js/jquery.lazyload.js 1627 "-" "-"
awk -F " " '{print $2}' test1.txt |sort -nr 对数字列进行倒序排序
uniq -c 对每行进行计数
awk -F " " '{print $1" "$2}' test1.txt |sort -n|uniq -c>test2.txt #第二次处理
1 /?= 46232
1 /static/flex/vedioLoading.swf 3583

1 /static/js/jquery.lazyload.js 1627

[root@ob data]# awk -F " " '{print (($1*$3))" " $2}' test2.txt|sort -nru #最后合并排序

#逻辑错误掉坑里写法,awk的特性是按行取数据,前一个数据会将第一个顶掉,所以在END时候只有最后一个数据,
[root@ob1 mytmp]# awk -F"GET |HTTP/1.1|200 " '{TP[$2]++}END{for (i in TP) print i,TP[i],$4}' /data/bb.txt|awk -F ' ' '{print $2*$3,$1}'|sort -nrk1

===================================================
第一步查看第二列
[root@ob1 data]# awk -F"GET | HTTP" '{print $2}' bb.txt
/static/images/photos/2.jpg
/static/images/photos/2.jpg
/static/flex/vedioLoading.swf
/?=
/static/js/web_js.js
/static/js/jquery.lazyload.js
第二步 属组取出
[root@ob1 data]# awk -F"GET | HTTP|200 | "-" '{tt[$2]++}END{for (i in tt)print i,tt[i]}' bb.txt
7
/?= 1
/static/js/web_js.js 1
/static/images/photos/2.jpg 2
/static/flex/vedioLoading.swf 1
/static/js/jquery.lazyload.js 1
第三步再次定义一个数组存放第三列,size[$2]+=$3,又买一个筐子存放第三列,可以使用相同的数组下表应为每一列相同
[root@ob1 data]# awk -F"GET | HTTP/1.1" 200 | "-" '{aa[$2]++;size[$2]+=$3}END{for (i in aa)print aa[i],i,size[i]}' bb.txt
awk: warning: escape sequence `-' treated as plain `-'
7 0
1 /?= 46232
1 /static/js/web_js.js 4460
2 /static/images/photos/2.jpg 22598
1 /static/flex/vedioLoading.swf 3583
1 /static/js/jquery.lazyload.js 1627
第三步计算排序
[root@ob1 data]# awk -F"GET | HTTP/1.1" 200 | "-" '{aa[$2]++;size[$2]+=$3}END{for (i in aa)print i,aa[i]*size[i]}' bb.txt|sort -nk 2
