How to escape single quote using awk in a bash script

Question

This is what I have so far, tried multiple ways but can\'t get it just right. My goal is to sanitize the input to prevent problems while inputting to mysql from text file

I'm not sure if I got the problem correctly. If you want to replace all occurrences of a single quote by a dot, use tr:

tr "'" "." < file.txt > sanitized.txt

If you want to escape the single quote with a backslash use sed like this:

sed "s/'/\\\'/g" file.txt > sanitized.txt

Note: Please take the advice from CharlesDuffy seriously. This is far from a stable and safe solution to escape values for an SQL import.
