u want to print first row with fourth column and second row with fifth column; the code is below
The error is shown with syntax error; what can be done
And another question is that if there is to print first row with fourth column and last row with fifth column; in each file; how the solution with awk will be?
First, please use CODE tags (not QUOTE tags) to show contents of files.
Second, we seem to have a language barrier. I do not understand what you want. Are you asking for a script that uses awk to read two lines from a file and write just column 4 from the 1st row and column 5 from the 2nd row? If this is what you want, you can get it using something like:
Are you asking for a script that reads a file and prints the 1st line that contains 4 or more columns and the 2nd line that contains 5 or more columns?
Please show us the output you want from the sample input you provide (in CODE tags) so we more clearly understand what you're trying to do.

Hi,
I want to write a shell script which increments a particular column in a row from a text file and then adds another row below the current row with the incremented value .
For Eg .
if the input file has a row :

I would like the script to create something like... (9 Replies)
Hello,
I have an input file like the following:
11_3_4
2_1_35
3_15__
_16989
Where '_' is a space. The data is in a table. Is there a way for the program to prompt the user for x1,y1 and x2,y2, where x1,y1 is the desired number (for example x=6 y=4 is a value of 4) and move to a desired spot... (2 Replies)
Hi, Please read the whole thread.
I have been working on this script below. It works fine, feel free to copy and test with the INPUT File below as well.
example:

Hi Friends,
I have a single column data like below.
1
2
3
4
5
I need the output like below.
0
1
2
3
4
where each row (including first row) subtracting from first row and the result should print below like the way shown in output file.
Thanks

Hi,
I have a comma separated file. I would like to print every alternate columns into a new row.
Example input file:
Name : John, Age : 30, DOB : 30-Oct-2018
Example output:
Name,Age,DOB

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
