Extract specific columns from delimited file using Awk

Question

Sorry if this is too basic. I have a csv file where the columns have a header row (v1, v2, etc.). I understand that to extract columns 1 and 2, I have to do: awk -F \

You can use a for-loop to address a field with $i:

ls -l | awk '{for(i=3 ; i<8 ; i++) {printf("%s\t", $i)} print ""}'
