Question

我正在尝试使用公共列从两个文件中提取数据，但我无法获取所需的数据。

File1
A   B   C   D   E  F  G
Dec 3  abc  10 2B 21  OK
Dec 1  %xyZ 09 3F 09 NOK
Dec 5  mnp  89 R5 11  OK

File2

 H   I
abc 10
xyz 00
pqr 45

我能够获得输出A B C D E F G但是无法在C＆amp; C之间添加I E栏。

Trail 1:

awk 'FNR==1{next}
 NR==FNR{a[$1]=$2; next}
 {k=$3; sub(/^\%/,"",k)} k in a{print $1,$2,$3,$4,a[$2],$5,$6,$7; delete a[k]}
  END{for(k in a) print k,a[k] > "unmatched"}' File2 File1 > matched

必需的输出：

matched: 
A   B   C   D  I  E  F  G
Dec 3  abc  10 10 2B 21  OK
Dec 1  %xyZ 09 00 3F 09 NOK
unmatched : 
 H  I
pqr 45

Could you please help me for getting this output please ? Thank you.

小心你在file1中有一个大写的Z.我把它放在我的测试中的小写 - 如果它不是一个错字，那是另一个要处理的小细节。

 $ awk 'FNR==1 {next}
        NR==FNR {a[$1]=$2; next}
        {k=$3; sub(/^\%/,"",k)}
        k in a {print $1,$2,$3,$4,a[k],$5,$6,$7; delete a[k]}
        END {for(k in a) print k,a[k] > "unmatched"}' File2 File1 > matched

$ cat matched
Dec 3 abc 10 10 2B 21 OK
Dec 1 %xyz 09 00 3F 09 NOK

$ cat unmatched
pqr 45

包含四列的文件2 ：

$ cat a
A   B   C   D   E  F  G
Dec 3  abc  10 2B 21  OK
Dec 1  %xyz 09 3F 09 NOK
Dec 5  mnp  89 R5 11  OK

$ cat b
 H   I  J   K
abc 10  j1 k1
xyz 00  j2 k2
pqr 45  j3 k3

$ cat x.awk
FNR==1 {next}
NR==FNR {a[$1]=$0; next}
{k=$3; sub(/^\%/,"",k)}
k in a {
    split(a[k], b)
    print $1,$2,b[2],$3,b[3],b[4],$4,$5,$6,$7; delete a[k]
}
END {for(k in a) print a[k] > "unmatched"}

$ awk -f x.awk b a
Dec 3 10 abc j1 k1 10 2B 21 OK
Dec 1 00 %xyz j2 k2 09 3F 09 NOK

$ cat unmatched 
pqr 45  j3 k3

如何在一个匹配列的awk中的两个文件中应用循环？
