Convert .txt file to .csv with header in bash

Question

.txt looks like:

I need a .csv file with a Header:

Date       Visit   Login           


        

Answer 1

This is a pure bash solution.Store the headers in an array and set IFS to tab and then echo the header. Loop through the file with read, set IFS to ; on the way in, set IFS to tab and run echo on the way out.

headers=(Date       Visit   Login  Euro      Rate)
((IFS=$'\t'; echo "${headers[*]}"); 
while IFS=';' read -r -a arr; do
(IFS=$'\t'; echo "${arr[*]}";)
done < test.fil) > test.csv
