I need a .csv file with a Header:

Answer 1

This should do it, if your fields don't contain any funny business:

(echo "Date;Visit;Login;Euro;Rate" ; cat file.txt) | sed 's/;//g' > file.csv

You'll just have to type a tab literally in bash (^V TAB). If your version of sed supports it, you can write\t instead of a literal tab.
