Is that what you are doing, or are you reading in from the file to the
variable $string directly?

If that's the case, then $string will contain the equivalent of "apple
\$fruit orange", where the "$" character in the text file is actually a "$"
character, not part of the variable $fruit.

Either way, assigning a value to fruit *after* you've set the value of
$string, will not change the value of $string.

Try the pattern-replacement method proposed by another responder... that
will account for the fact that you are looking at a text string, rather
than a string with a variable embedded in it.
