depending on the language the quotes matter. A simple example can be done in bash, where quotes are everything:

bash$: "I am `whoami`"
I am root
bash$: 'I am `whoami`'
I am `whoami`

In the case of bash ( and many other languages ), using single quotes, vs double quotes has serious implications. Check the language you're using for documentation on how each token is treated.
