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.
Desired Output:
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?
Hello,
I have a number of tab delimited data files consists of two columns. Like that:

Hi there,
I'm trying to merge two files and make a third file.
However, two of the columns need to match exactly in both files AND I want everything from both files in the output if the two columns match in that row.
First file looks like this:

Hi,
I have two text files that I would like to merge/join. I would like to join them if the first columns of both text files match and the second column of the first text file matches the third column of the second text file.
Example input:
First file:

algorithm::munkres
Algorithm::Munkres(3pm) User Contributed Perl Documentation Algorithm::Munkres(3pm)NAME
Algorithm::Munkres - Perl extension for Munkres' solution to
classical Assignment problem for square and rectangular matrices
This module extends the solution of Assignment problem for square
matrices to rectangular matrices by padding zeros. Thus a rectangular
matrix is converted to square matrix by padding necessary zeros.
SYNOPSIS
use Algorithm::Munkres;
@mat = (
[2, 4, 7, 9],
[3, 9, 5, 1],
[8, 2, 9, 7],
);
assign(@mat,@out_mat);
Then the @out_mat array will have the output as: (0,3,1,2),
where
0th element indicates that 0th row is assigned 0th column i.e value=2
1st element indicates that 1st row is assigned 3rd column i.e.value=1
2nd element indicates that 2nd row is assigned 1st column.i.e.value=2
3rd element indicates that 3rd row is assigned 2nd column.i.e.value=0
DESCRIPTION
Assignment Problem: Given N jobs, N workers and the time taken by
each worker to complete a job then how should the assignment of a
Worker to a Job be done, so as to minimize the time taken.
Thus if we have 3 jobs p,q,r and 3 workers x,y,z such that:
x y z
p 2 4 7
q 3 9 5
r 8 2 9
where the cell values of the above matrix give the time required
for the worker(given by column name) to complete the job(given by
the row name)
then possible solutions are:
Total
1. 2, 9, 9 20
2. 2, 2, 5 9
3. 3, 4, 9 16
4. 3, 2, 7 12
5. 8, 9, 7 24
6. 8, 4, 5 17
Thus(2) is the optimal solution for the above problem.
This kind of brute-force approach of solving Assignment problem
quickly becomes slow and bulky as N grows, because the number of
possible solution are N! and thus the task is to evaluate each
and then find the optimal solution.(If N=10, number of possible
solutions: 3628800 !)
Munkres' gives us a solution to this problem, which is implemented
in this module.
This module also solves Assignment problem for rectangular matrices
(M x N) by converting them to square matrices by padding zeros. ex:
If input matrix is:
[2, 4, 7, 9],
[3, 9, 5, 1],
[8, 2, 9, 7]
i.e 3 x 4 then we will convert it to 4 x 4 and the modified input
matrix will be:
[2, 4, 7, 9],
[3, 9, 5, 1],
[8, 2, 9, 7],
[0, 0, 0, 0]
EXPORT
"assign" function by default.
INPUT
The input matrix should be in a two dimensional array(array of
array) and the 'assign' subroutine expects a reference to this
array and not the complete array.
eg:assign(@inp_mat, @out_mat);
The second argument to the assign subroutine is the reference
to the output array.
OUTPUT
The assign subroutine expects references to two arrays as its
input paramenters. The second parameter is the reference to the
output array. This array is populated by assign subroutine. This
array is single dimensional Nx1 matrix.
For above example the output array returned will be:
(0,
2,
1)
where
0th element indicates that 0th row is assigned 0th column i.e value=2
1st element indicates that 1st row is assigned 2nd column i.e.value=5
2nd element indicates that 2nd row is assigned 1st column.i.e.value=2
