How do I use single quotes inside single quotes?

Question

Can anyone explain how to make this code work?

echo \'
Welcome 
\'         


        

Answer 1

Inside single quotes, variable names aren't parsed like they are inside double-quotes. If you want to use single-quoted strings here, you'll need to use the string concatenation operator, .:

echo '
Welcome 
';

By the way: the answer to the question in the title is that in order to use a literal single-quote inside a single-quoted string, you escape the single-quote using a backslash:

echo 'Here is a single-quote: \'';
