Question

文件A有以下3列： AccountNumber，客户名称，余额

文件B有以下5列 SystemID，AccountNumber，Product，OpeningDate

我使用下面的AWK代码加入这两个文件。它无法正常工作

FNR==NR{a[$1]=$0;next}$2 in a{ print $0, a[$1]}

两个文件的组合输出预计如下 SystemID，AccountNumber，Product，OpeningDate，CustomerName，Balance

仅在AWK代码中请求帮助。我知道通过SORT和JOIN可以获得类似的功能，但我只是在寻找AWK解决方案。

File A:
+---------------+---------------+----------+
| AccountNumber |  CustomerName |  Balance |
+---------------+---------------+----------+
|             3 | C             |      100 |
|             4 | A             |      200 |
|             5 | B             |      300 |
+---------------+---------------+----------+

File B:
+-----------+----------------+----------+--------------+
|  SystemID |  AccountNumber |  Product |  OpeningDate |
+-----------+----------------+----------+--------------+
|         1 |              6 | RD       | 12-05-17     |
|         2 |              4 | SB       | 15-05-17     |
|         3 |              3 | TD       | 02-04-17     |
|         4 |              5 | SB       | 15-01-17     |
+-----------+----------------+----------+--------------+

Output after joining:
+-----------+----------------+----------+--------------+--------------+---------+
|  SystemID |  AccountNumber |  Product |  OpeningDate | CustomerName | Balance |
+-----------+----------------+----------+--------------+--------------+---------+
|         2 |              4 | SB       | 15-05-17     | A            |     200 |
|         3 |              3 | TD       | 02-04-17     | C            |     100 |
|         4 |              5 | SB       | 15-01-17     | B            |     300 |
+-----------+----------------+----------+--------------+--------------+---------+

如果你可以删除管道，加上和 - 下面的符号是解决方案 -

cat file1
1 6 RD 12-05-17
2 4 SB 15-05-17
3 3 TD 02-04-17
4 5 SB 15-01-17

cat file2
3 C 100
4 A 200
5 B 300

awk 'NR==FNR{a[$1]=$2FS$3;next} $2 in a {print $0, a[$2]}' file2 file1
2 4 SB 15-05-17 A 200
3 3 TD 02-04-17 C 100
4 5 SB 15-01-17 B 300

在AWK中连接两个文件 - 在不同位置加入列
