Question

我有两个文件（文件1和文件2）
我试图将File1的Column1和2的字符串与File4的Column4和5进行比较。除了这个匹配，File2的column6也需要匹配某些字符串，如SO或CO（因为FILE1的column3和4分别是SO和CO），然后将FILE2的column7替换为FILE1的column3，否则保持其他不变。< / p>

我尝试修改并使用论坛中提供的解决方案来解决类似的问题，但是没有用。

FILE1
type  code     SO  CO other

7757    1       6941.958        138.922 149.17

FILE2
"US","01073",,"7757","1","SO","10","299"
"US","01073",,"7758","1","SO","10","299"
"US","01073",,"7757","1","NO","10","299"
"US","01073",,"7757","1","CO","10","299"

"US","01073",,"7757","1","GO","10","299"
"US","01073",,"7805","6","CO","10","299"

Required output:

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

我试过的解决方案（仅适用于CO）：

tr -d '"' < FILE2 > temp  # to remove double quote
awk 'NR==FNR{A[$1,$2]=$3;next} A[$4,$5] && $6=="CO" {$7=A[$1,$2]; print}' FS=" " OFS="," FILE1 temp > out

Answer 1

复杂的 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

function unquote(f) { ... } - 在双引号之间取消引用/提取值（事实上 - 在字符串的第1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",,"7757","1","SO",6941.958,"299"
"US","01073",,"7758","1","SO","10","299"
"US","01073",,"7757","1","NO","10","299"
"US","01073",,"7757","1","CO",138.922,"299"
"US","01073",,"7757","4","MO","10","299"
"US","01073",,"7757","1","GO","10","299"
"US","01073",,"7805","6","CO",75.175,"299"

比较多列，只有匹配才能替换
