title: Handle bash variable that may include dollar sign?
body: <p>I have a script that accepts user input which may contain special characters.  I run that variable through a sed recipe that will find and escape special characters, but if the variable contains a '$' the output is truncated.  How can I automagically escape any dollar sign that may appear in the variable?  Or do I just have to echo back a message, "If there's a dollar sign you must prepend a backslash to it"?</p>
