How to print and store specific named columns from csv file with new row numbers

Question

start by saying, I\'m very new to using bash and any sort of script writing in general.

I have a csv file that has basic column headers and values underneath which look

Answer 1

Like this? Using awk:

$ awk 'NR>1{print NR-1, $2}' file
1 3
2 5
3 5
4 8

Explained:

$ awk '              # using awk for the job
NR>1 {               # for the records or rows after the first
    print NR-1, $2   # output record number minus one and the second field or column
}' file              # state the file

I would like to be able to do this for various different named column headers. With awk you don't specify the column header name but the column number, like you don't state b but $2.
