I'm trying to store all the values into variables so I can use them later, I've found and example which is useful, but in the example only has 3 columns, and the files that I'm working on have a lot more, this is the code:



#!/usr/bin/awk -f

 array1[NR]=$3;array2[NR]=$4;array3[NR]=$5 

END
 for(i=1;i<=NR;i++)
 print "Column"i" "array1[i]
 for(i=1;i<=NR;i++)
 print "Column"i" "array2[i] 
 for(i=1;i<=NR;i++)
 print "Column"i" "array3[i]



That I want to do is, first to iterate trough all the columns and store them in an array starting from column number 3, because column 1 and 2 are the date.



Second, then I want to work to iterate through everything to print a new line with every value on the array. something like this:



BEGIN
 for(i=1;i<=NR;i++)
 for(j=1;j<=NR;j++)
 array$i<--arrayname based con the for variable[NR]=$j<---column number based on the for variable



I wasn't able to use the FOR variables to create the array name, so I get an error.



After that I want to do the second part in the example but using the same logic, I iterate through every thing to create new lines.



Appreciate your help.



EDIT: I'm trying to use the 3 value of the second record which is the CPU User%

    You have 7 lines of input that produces about 14 lines of output. The values for value don't make sense. I'm utterly confused. Are the last column timestamps? They are out of range. In any case, you don't need arrays for this.

  • Do you have an example where you actually need to store all the files data before processing it from your arrays in the END block? What's stopping you from just storing $0 from each line and then using split() on these later in that case?

  • Hello, ok I think that what is doing for example the first array1[NR]=$3 is storing into record all the information from column 3, which is what I want, the thing is that I have 139 columns so I don't want to declare every array manually. That is what I want to create all 139 arrays using a for loop and using the current value of iteration, for example when i=1 create an array called array1, and so on.

    At least if you have a fairly recent version of GNU awk, you can use Arrays of Arrays

    You have 7 lines of input that produces about 14 lines of output. The values for value don't make sense. I'm utterly confused. Are the last column timestamps? They are out of range. In any case, you don't need arrays for this.

It's not clear to me what you expect to happen here: NR is the record (line) number - if you want to loop over columns (fields) the variable you need to refer to in your loop is NF; in any case, both will be zero inside a BEGIN block
