How to add single quotes around columns using awk

Question

Just wondering how can I add single quotes around fields, so I can import it to mysql without warnings or errors.

I have a csv file with lots of content.

Answer 1

You could try this

awk -F"," -v quote="'" -v OFS="','" '$1=$1 {print quote $0 quote}' file

1. Replace each separator (, comma) with (',' quote-comma-quote) -> (-F"," -v OFS="','")
2. Add quotes to the begin and end of line -> (print quote $0 quote)
