查找已发送及其即时接收-仅用于匹配的会话号

将所有会话匹配的“接收”与相同的“发送”组合起来。例如：会话：123

如果没有“接收”，则打印NOMATCH

试试这个：

awk -F "[:,]"  '{split($2,a,",");if($1~/sent/){if(prev!~/receive/&& NR!=1)print prev,"NOMATCH";else if (NR!=1)print prev;prev=$0;session=a[1];}if($1~/receive/&&session==a[1]){prev=prev","$0;}}'END'{if(prev~/receive/)print prev;}' file1.txt

测试：

>cat temp
abc message=sent session:111,x,y,z
pqr message=receive session:111,4,5,7
abc message=sent session:123,x,y,z
pqr message=receive session:123,4,5,7
pqr message=receive session:123,4x,5x,7x
pqr message=receive session:123,4p,5q,7r
abc message=sent session:342,x,y,z
abc message=receive session:311,x,y,z
abc message=sent session:589,x,y,z
pqr message=receive session:589,4,5,7
>

> 
> awk '{x=substr($3,0,match($3,","));a[x]?a[x]=a[x]","$0:a[x]=$0}END{for(i in a){print a[i],a[i]~/sent/&&a[i]~/receive/?"":"NOMATCH"}}' temp

谢谢你，戈帕尔。。但产出不同。。最后一张唱片不知怎么的漏掉了，这和你之前问的问题不一样吗？不这一次，我们尝试合并符合条件的所有行。。以前我们只合并了两行。我知道这是一样的，但我试图修改以前的帖子，但没有成功。@VipinChoudhary，为什么你在第一次合并时删除了

pqr

，而没有删除其他的呢？对不起。。那是打字错误。。现在改正
