2018-05-11 awk按照指定内容匹配按照行合并两个文件

终于初步实现了效果：
nid30_0507_rm.txt 为 7个转化日志，nid30_0507_rm_clicktoconver.txt 为14行,每两行中第一行是点击的clickid,第二行是点击日志。
现在要把nid30_0507_rm_clicktoconver.txt中点击clickid替换成转化日志，达到快速查看效果。

下面的不加 NR!=FNR结果真的不一样(不加就显示21行,等同于cat合并两个文件)！加了表示只在读取第二个文件时print 内容。不加else也是显示21行（结果还可以接受。等同于每三行描述一个转化对应的点击。就是把转化日志插入到clickid和点击日志的上面.没有else表示输出第二个文件的所有行，所以没有删除只有clickid的行）。

2721 $ awk -F"|" 'NR==FNR{a[$1]=$0};NR!=FNR{if($0 in a)print a[$0];else print $0}' nid30_0507_rm.txt nid30_0507_rm_clicktoconver.txt|nl
