awk |合併連續2行場匹配的基礎上的文件

Question

我需要幫助與以下：

輸入文件：

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 
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 

輸出文件：

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 
abc message=sent session:342,x,y,z, NOMATCH 
abc message=sent session:589,x,y,z, pqr message=receive session:589,4,5,7 

注：

如果您在源文件中看到，對於每個「發送」消息，都有「接收」
對於每個「=發送」，搜索f或「=接收」在立即下一行僅適用於相同的會話號碼
因此，只合並那些發送和接收，我們有匹配的會話號碼ELSE打印發送，因爲它是在一個序列
只有會話= 342有沒有收到
會話不明，不能硬編碼

Answer 1

awk 
'{ 
split($3,a,","); 
if($2~/sent/) 
{ 
    if(prev!~/receive/ && NR!=1) 
    print prev,"NO MATCH";prev=$0;session=a[1]; 
} 
if($2~/receive/&&session==a[1]) 
{ 
    print session, prev,$0;prev=$0 
} 
}' temp 

測試：

> 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 
abc message=sent session:342,x,y,z 
abc message=sent session:589,x,y,z 
pqr message=receive session:589,4,5,7 

> awk '{split($3,a,",");if($2~/sent/){if(prev!~/receive/&& NR!=1)print prev,"NO MATCH";prev=$0;session=a[1];}if($2~/receive/&&session==a[1]){print session, prev,$0;prev=$0}}' temp 
session:111 abc message=sent session:111,x,y,z pqr message=receive session:111,4,5,7 
session:123 abc message=sent session:123,x,y,z pqr message=receive session:123,4,5,7 
abc message=sent session:342,x,y,z NO MATCH 
session:589 abc message=sent session:589,x,y,z pqr message=receive session:589,4,5,7

，或者你可以簡單地將代碼放在一個文件作爲貝羅女：

> cat tmp.awk 
#!/usr/bin/awk 

{ 
split($3,a,","); 
if($2~/sent/) 
{ 
    if(prev!~/receive/ && NR!=1) 
    print prev,"NO MATCH";prev=$0;session=a[1]; 
} 
if($2~/receive/&&session==a[1]) 
{ 
    print session, prev,$0;prev=$0 
} 
} 
> 

，並如下執行：

> awk -f tmp.awk temp 
session:111 abc message=sent session:111,x,y,z pqr message=receive session:111,4,5,7 
session:123 abc message=sent session:123,x,y,z pqr message=receive session:123,4,5,7 
abc message=sent session:342,x,y,z NO MATCH 
session:589 abc message=sent session:589,x,y,z pqr message=receive session:589,4,5,7
