Awk 比较多列并仅在匹配时替换 我有两个文件（文件1和文件2）

我试图将File1的Column1和column2的字符串与File2的Column4和column5进行比较。除此匹配外，File2的第6列还需要匹配某些字符串，如SO或CO（因为FILE1的第3列和第4列分别为SO和CO），然后将File2的第7列替换为FILE1的第3列，否则保持其他字符串不变

我试图修改并使用论坛中针对类似问题提供的解决方案，但没有成功

Required output:

我尝试的解决方案（仅适用于CO）：

tr-d'temp#删除双引号
awk'NR==FNR{A[$1，$2]=$3；next}A[$4，$5]&&&$6==“CO”{$7=A[$1，$2]；print}'FS=”“OFS=“，”FILE1 temp>out

---

复合awk解决方案：

awk 'function unquote(f){ 
         return substr(f, 2, length(f)-2) 
     }
     NR==FNR{ 
         if (NR==1){ f3=$3; f4=$4 }
         else if (NF){ a[$1,$2,f3]=$3; a[$1,$2,f4]=$4 }
         next; 
     }
     { k=unquote($4) SUBSEP unquote($5) SUBSEP unquote($6) }
     k in a{ $7=a[k] }1' file1 FS=',' OFS=',' file2

• 函数unquote（f）{…}

  -unquotes/在双引号之间提取值（事实上，在字符串的第一个和最后一个字符之间）

• a[$1，$2，f3]=$3；a[$1，$2，f4]=$4

  -对关键序列进行分组

输出：

"US","01073",,"7758","1","SO","10","299"

非常感谢您帮助编辑我的代码！Randomir。您好RomanPerekhrest，谢谢您的帮助。您的脚本对我来说非常棒。但是我一直得到与“file2”相同的输出，这意味着在输出的第7列中没有任何替换。有什么提示吗？@kelly，提示：确保你已经发布了实际的输入样本，因为它们是复制和测试的。该解决方案对于当前发布的samplesRomanPerekhrest工作良好，这是我的问题，您的代码工作得非常完美。非常感谢您的帮助和时间。@kelly，没问题，@RomanPerekhrest的解决方案与测试数据完美结合。然而，文件2中的实际数据存在问题：第2列类似于“abc，45”或“abc23”，这意味着有些双引号内有逗号，有些则没有。既然我不能用双引号作为这个问题的分隔符，该如何处理呢？谢谢你的帮助。
