Re^2: syntax error near unexpected token `)'

Then how to handle a single quote match?

[zwon]

This sounds more like a bash question to me, but you can replace single quotes with \N{APOSTROPHE} or \x27. In bash you can do it like this:

$ echo 'aa'"'"'bb';
aa'bb

Alternatively and one shorter: Change ' to '\''.

$ echo 'aa'\''bb';
aa'bb
