You need to post your code for us to be able to help you.

Simply saying it does not do what you expect does not help - we need to know what "it" is before we can help.

Update: - I'm guessing what you mean is that if a particular array element contains more than one single-quote, only the first single-quote gets escaped/replaced, in the code I posted.

This is correct. If you need all of them replaced, use the "g" option in the regular expression . 

s/'/\\'/g for @a;
