awk比较7个文件，打印匹配和基于文件的差异：

Question

我需要将7个文件( Ref.txt和Jan.txt )包含到Jun.txt，并获得匹配和非匹配，在这种情况下，我希望用Jan.txt到Jun.txt的第一个字段检查Ref.txt的第二个字段，如果是，则打印Ref.txt (主转储)的所有文件，然后将Jan.txt的整个行打印到Jun.txt。如果没有在Jan.txt上找到与Jun.txt匹配的语句，则声明"NotFound“。

Ref.txt

abc 10  xxyyzz
bdc 20  xxyyzz
edf 30  xxyyzz
ghi 40  xxyyzz
ofg 50  xxyyzz
mgf 60  xxyyzz

Jan.txt

10  Jan 100
30  Jan 300
50  Jan 500

Feb.txt

10  Feb 200
20  Feb 400
40  Feb 800
60  Feb 1200

Mar.txt

20  Mar 600
50  Mar 1500

Apr.txt

10  Apr 100
30  Apr 300
50  Apr 500

May.txt

10  May 200
20  May 400
40  May 800
60  May 1200

Jun.txt

20  Jun 600
50  Jun 1500

期望产出：
