Merging two files based on matching columns
Hi,

I am facing issues while accomplishing below task.

We have two files Test1.txt and Test2.txt. We have to match 1st column of Test1.txt file with 2nd column of Test2.txt and then merge 2nd file with the 1st file. In the output we should select column 1 and 2 from the 1st file and column 1 and 3 from the 2nd file. If there is no match with the 1st file then blank should be appended in output.
Code:
$ cat Test1.txt
Amar,Movies,12
Sanjay,Cricket,18
Rakesh,Football,35
Samit,Cricket,56
Sam,Songs,20
Ram,Books,40
$

Code:
$ cat Test2.txt
1,Samit,Service
2,Sam,DJ
3,Rakesh,Police
$

Desired Output:
Code:
Amar,Movies,,
Sanjay,Cricket,,
Rakesh,Football,3,Police
Samit,Cricket,1,Service
Sam,Songs,2,DJ
Ram,Books,,

I have tried to do this with awk but, could not get it.

Also, please advise how can we represent individual fields from two files?
For example, if I pass two files (Test1.txt and Test2.txt) to awk then, how will I differentiate or represent 1st/2nd field of the Test1.txt and 1st/2nd field of the Test2.txt?

Thanks in advance for your help in this regards.
